While taking a girl from behind, grab some dice, and as you shoot your load scream "Yahtzee!!!" and roll the dice down her back. The object of the game is very similar to the actual game as you and your friends should note your antics and keep score. "Yahtzee!!!" must be yelled upon every roll of the dice down her back regardless of the score!
He pulled The Milton Bradley on his girlfriend last night, rolled five 6's ... amazing.
