A game where guys sit around a poker table and a girl goes under the table and performs oral sex on one guy and they place bets on who is getting it. Winner is the guy who finishes and no one guesses right.
The other night during the poker game we got Amy to play Mongolian Roulette and Bill didn't flinch so he won $100.
