A crib hand, in the card game cribbage, which has twelve or more points. (Thus, all cribalicious hands are cribtastic, but not all cribtastic hands are cribalicious.) Saying the word must always be accompanied by a dance-like rolling motion of one's shouldersup and down, and a sassy bobbing of one's head.
Ivan: Twelve points!
Cole: That's cribtastic!
Ivan: <rolling shoulders sexily from side to side, and bobbing his head> It's cribalicious!
