An unending game involving more than one participant. The objective of ninja is simple. Fart in your hand, sneak up behind the unsuspecting victim, then cover both their nose and mouth in attempt to "assassinate" them. Ninja can start at any time. There are no rules or restrictions to your assassination attempts, but they must be carried out in the fashion mentioned above. The game will end when the other party specifically expresses they want to quit the game. (If they know what the game is.) Or if they gag or excrete any type of bile. If none of these are met, then the came will continue until then.
Me and bob were hanging out in the kitchen one night, until I farted in my hand while he was busy and cuffed his mouth and nose in attempt to assassinate him like a Ninja.
