At a party or any other social function:

-Buy a box of condoms
-Take out one condom
-Take a pin and puncture the condom while in the wrapper
-Put the punctured condom back into the box
-Let people take the condoms freely

Much like russian roulette, this will end up with your life ending.

Mexican Roulette is similar to the game known as Russian Roulette. However, instead of bullets, your ammunition is your ass gas. One person farts, and the other returns fire. To win you must only fart, but not shart or soil yourself.
