Ice man is a colloquial term given to someone who is unusually calm and focused under pressure.

While playing poker, Commander Riker called Lt. Worf "ice man" after winning at least two consecutive hands of the game. (TNG: "The Emissary")

The Klingon term for "ice man" is d'akturak. Federation Ambassador Curzon Dax gave this nickname to Koloth at the Korvat colony negotiations, referring to Koloth's "icy" demeanor at those negotiations. (DS9: "Blood Oath")

According to the script for "Blood Oath", d'akturak was pronounced as " dak-TUR-ak". [1]
