Bird in a gilded cage Edit

To be a bird in a gilded cage was to live in luxury without freedom.

In 2268, Kirk described the crew of the USS Enterprise on the planet Mudd as birds in a gilded cage and asked how they could escape, to which Pavel Chekov replied that he had no ideas but that it was a very nice gilded cage. Kirk reminded everyone that despite it containing their deepest desires, it was a cage nonetheless and that they belonged back on the Enterprise. (TOS: "I, Mudd")

Black and white Edit

To be "black and white" was for something to be either one thing or another, with no in between. The term was also related to another idiom, "cut and dry", and was the opposite of "a shade of gray".

Break the ice Edit

To "break the ice" meant to introduce conversation or small talk into an awkward situation.

  • In 2151, Captain Jonathan Archer called a planned dinner with Vulcan Captain Vanik, he described the event as a "good way to break the ice." (ENT: "Breaking the Ice")
  • In 2171, The Doctor changed his program so that he would no longer say "Please state the nature of the medical emergency" when activated. When Kes discovered that he changed it back, and asked why, The Doctor explained that "I became so uncomfortable trying to find new ways to break the ice, as it were, that I restored it. Let's just say it works for me." (VOY: "Tattoo")

Burning the midnight oil Edit

In 2376, Captain Kathryn Janeway, who was working very late one night in the mess hall, told Neelix that she was "just burning the midnight oil", to which Neelix replied that it was way past midnight. (VOY: "Fair Haven")

In an alternate timeline in 2364, Captain Jean-Luc Picard ordered Miles O'Brien to bypass the secondary plasma inducer, which required O'Brien to realign the entire power grid, stating "we're all going to be burning the midnight oil on this one." Data, who overheard O'Brien, told him that that would be inadvisable because any "attempt to ignite a petroleum product on this ship at 0:00 hours [would] activate the fire suppression system." (TNG: "All Good Things...")

Referred to one was so caught up in small details that they were not able to see the bigger picture.

In 2285, James T. Kirk characterized his having been trapped by Khan Noonien Singh as having been caught with his britches down, a fact he attributed to his own supposed senility. (Star Trek II: The Wrath of Khan)

In 2366, Geordi La Forge opined that Romulan defector Alidar Jarok was correct about Romulan activity at Nelvana III, and that the Romulans would indeed be caught with their pants down. Data, unfamiliar with the phrase, questioned what he meant, and La Forge explained. (TNG: "The Defector")

In 1986, Gillian Taylor told time traveler Admiral James Kirk, when he explained to her that they wanted to bring George and Gracie to the 23rd century, and asked her if she was curious about the details, she said, "I wouldn't miss it for all the tea in China." (Star Trek IV: The Voyage Home)

It was used in that capacity during Worf's 2371 promotion ceremony, which included holodeck roleplaying on an sea vessel and involved him walking the plank. (Star Trek Generations)

A variant of the phrase, "May God have mercy on our souls," was used by Malcolm Reed to end his final log entry when stranded in Shuttlepod 1 and he believed there was no chance of rescue. (ENT: "Shuttlepod One")

Media circus Edit

"Media circus" was a Human idiom which described a news event where the coverage was out of proportion to the event itself.

Needle in a haystack Edit

"Needle in a haystack" was a Human idiom which described the long-lasting search for something in a large variety of possibilities.

In 2267, when searching for the Galileo, James Kirk remarked to High Commissioner Ferris, "Finding a needle in a haystack would be child's play." (TOS: " The Galileo Seven")

Later in the episode's script, just after Kirk decides to search Taurus II for the Galileo, Ferris disapprovingly commented, "You said something about a needle in a haystack. Useless..." and Kirk replied, "Not if you want your needle back."

In 2364, William Riker described searching Starfleet records for an instance of someone showering in their clothes as "like looking for a needle in a haystack." (TNG: "The Naked Now")

In 2369 while searching for the crash landed runabout USS Yangtzee Kiang in the Gamma Quadrant, Miles O'Brien compared the search with searching for a "bloody needle in a haystack." O'Brien and Jadzia Dax had to search several planets, two dozen moons, and an asteroid belt. (DS9: "Battle Lines")

In 2370, a Paradan replicant of O'Brien commented "Needle in a haystack wouldn't do this job justice" when searching for a fault in Deep Space 9's upper pylons. (DS9: "Whispers")

In 2373, Jadzia Dax said to Benjamin Sisko "Do the words 'needle in a haystack' mean anything to you," after the USS Defiant had spent two days unsuccessfully searching the Badlands for cloaked missiles appropriated by the Maquis for a strike against Cardassia. (DS9: "Blaze of Glory")

On a silver platterEdit

Referring to something that was offered to someone in a rather obvious manner.

  • In 2375, Neelix offered B'Elanna Torres the chance to insult his cooking by telling her to name her poison. After she missed that chance, he seemed disappointed, claiming he'd handed it to her on a silver platter. (VOY: "Extreme Risk")

One-way street Edit

Meaning: The term referred to an agreement made by two parties, but only one party benefits from.

Penny for your thoughts Edit

"A penny for your thoughts" was a Human idiom, meaning that someone was curious about what the other person was thinking.

In 2368, Doctor Beverly Crusher used the expression when she wanted to get Jean-Luc Picard to talk to her during a conversation. When Picard asked her if she has one, she told him that the replicator probably has it on file. (TNG: "The Perfect Mate")

In 2369, when Q brought back Picard to the incident at Starbase Earhart in 2327, he told him (acting as a bartender): "Penny for your thoughts? You never told me you were such a lady's man," also jokingly referring to Picard's unsuccessful date with Penny Muroc. (TNG: "Tapestry")

In 2370, Crusher used the expression again, dining with Picard, after they shared thoughts for a time via the psi-wave device on Kesprytt III. (TNG: "Attached")

In 2257, Amanda Grayson spoke of a similar idiom, "Isik for your thoughts," which she described as a Vulcan, but was later revealed as something she heard her mother say. (DIS: "Despite Yourself", "Will You Take My Hand?")

Play our cards rightEdit

Referring to "if things go well."

Play possumEdit

Meaning: To feign death when an enemy approached.

  • In 2377, when Chakotay suggested the Hirogen might be laying a trap for Voyager, Kathryn Janeway dismissed the idea, saying that the Hirogen "aren't the type to play possum." (VOY: "Flesh and Blood")
Janeway uses the term incorrectly here, as it refers to an (o)possum's tendency to play dead in the hopes that an enemy will go away, rather than lying in wait to attack. [1]

Playing twenty questions Edit

Rather than playing an actual guessing game, this meant to make somebody ask questions rather than telling them directly what a problem or the answer was.

When Harry Kim claimed to be an American during the Hirogen simulation of World War II in 2374, Tom Paris became annoyed at the man's refusal to answer him, saying he didn't have time to play twenty questions. (VOY: "The Killing Game")

Kathryn Janeway told Neelix the same thing when he was less than forthcoming about the delicate issue of non-functioning lavatories on USS Voyager in 2375. (VOY: "Bride of Chaotica!")

The powers that be Edit

"The powers that be" was a phrase referring to a decision made by those in power, or the decision makers, without going into detail who those decision makers were (as it was not relevant to the story.)

In 2143, when Jonathan Archer and A.G. Robinson were attempting to take NX Alpha on a test flight, Archer informed A.G. of the good news that he had just gotten word from "the powers that be" that he was good to go for launch. (ENT: "First Flight")

In 2256, Saru explained that he had been assigned to the USS Discovery as first officer by "the powers that be" after the destruction of the USS Shenzhou. (DIS: "Context Is for Kings")

Preaching to the choir Edit

"Preaching to the choir" was a phrase used to describe someone who was trying to convince another who was already a believer.

The real McCoy Edit

"The real McCoy" described anything which was the genuine article in question, not merely a facsimile thereof.

In 2374, Vic Fontaine revealed to Odo that a new improved version of the "Lola Chrystal" hologram was in fact Kira Nerys, who the hologram's features were based on, and that the Changeling had been dancing with the real McCoy. (DS9: "His Way")

In 2375, "Boothby" classified Chakotay, unlike himself, to be "the real McCoy", (i.e. not a Species 8472 recreation of a Starfleet officer) and recommended "Valerie Archer" perform a genetic extraction in order to figure out a better way for members of Species 8472 to maintain a Human appearance. (VOY: "In the Flesh")

Rich beyond the dreams of avarice Edit

Doctor Leonard McCoy managed to convince Dr. Nichols to accept the formula for transparent aluminum as compensation for his services by saying that once he figured out the dynamics of the matrix (which would take years), he'd be rich beyond the dreams of avarice. (Star Trek IV: The Voyage Home)

Run off at the mouth Edit

In response, Spock stated stated "sauce for the goose, Mr. Saavik." (Star Trek II: The Wrath of Khan)

Shade of gray Edit

To have a "shade of gray" meant to not be clear what was right or wrong, or good and evil, but instead existed in a gray area. The term was the opposite of what it mean to be black and white.

  • Following Worf's transfer to Deep Space 9 in 2372, Captain Benjamin Sisko explained that "Starfleet officers often have trouble learning the unofficial rules of the station," as contrary to serving aboard the USS Enterprise-D, Worf "always knew who were my allies and who were my enemies." Sisko reiterated the discussion, adding, "Let's just say DS9 has more shades of gray. And Quark definitely is a shade of gray. He has his own set of rules and he follows them diligently. Once you understand them, you understand Quark. I'd say that's true for everyone here." (DS9: "Hippocratic Oath")
  • After Captain Sisko's time in captivity with Gul Dukat, following the destruction of the USS Honshu, he explained to Jadzia Dax that he always thought "sometimes life seems so complicated. Nothing is truly good or truly evil. Everything seems to be a shade of gray." However, recalling his experience, he continued, "And then you spend some time with a man like Dukat and you realize that there is really such a thing as truly evil." (DS9: "Waltz")

Sight for sore eyes Edit

Meaning: Something that was pleasing to look at.

  • In 2376, Harry Kim remarked that he would not want to bunk with the great explorers of the past. Tom Paris remarked that that would be a sight for sore eyes. (VOY: "Memorial")

Furthermore, Captain Archer used the expression in a deleted scene from "The Expanse".

Stone knives and bearskins Edit

"Stone knives and bearskins" was a colorful term employed by Spock to describe the 1930s technology he was forced to use to construct a tricorder interface. Vital information was locked within Spock's tricorder: How had Leonard McCoy changed history? Spock was eventually able to construct an appropriate circuit, but retrieved two separate recordings: one in which Edith Keeler lived, and one in which she died. At that point, the improvised interface erupted in sparks and flame, ruining his chance to learn which of the recordings represented McCoy's alteration, and which the correct timeline. (TOS: "The City on the Edge of Forever")

Kathryn Janeway also used this expression when typing on a late 20th century computer keyboard trying to find out information about Henry Starling. (VOY: "Future's End")

That's life Edit

"C'est la vie" (French: "that's life") was a Human idiom, meaning bad things happen, it was the way of life.

In 2285, when Admiral James Kirk self-destructed the USS Enterprise, killing most of Kruge's Klingon crew on board, he told the commander on the surface of the Genesis Planet: "Sorry about your crew, but as we say on Earth, ...'c'est la vie.'" (Star Trek III: The Search for Spock)

Having one's name on something meant that the object in question belonged to or was reserved for them.

In 2372, Julian Bashir assured Odo that there was a Spitfire with his name on it in the hangar if he wanted to join the Battle of Britain holoprogram. Later, Joseph Sisko told his grandson there was a vat of crayfish that needed cleaning with his name on it. (DS9: "Homefront")

In 2375, Miles O'Brien told Janel Tigan he was not looking forward to seeing Captain Sisko again, as he had a boot with O'Brien's name on it. (DS9: "Prodigal Daughter")
