Mongolian roulette is when you are not sure whether you have to poop or fart, and choose to attempt to fart anyways.
1. I played a dangerous game of Mongolian Roulette on the way home from work, I got so close to losing I had to run into the bathroom

2. Ive been playing Mongolian Roulette for the last half hour and I'm afraid I'm at the last chamber.

Get the Mongolian Roulette mug.
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.
