Yahtzee
Yahtzee was a dice game from Earth. It was customary for a player to yell "Yahtzee" after making a particularly successful roll.
During an away mission to comet C/2260-Quentin in 2259, Lieutenant Sam Kirk said "Yahtzee" when an egg-shaped alien device activated upon his stepping on its supporting dais. He began explaining the phrase to Commander Spock, who interrupted to note that he was already familiar with the game. (SNW: "Children of the Comet")
