The Stink Bomb

when a girl has her period, the guy puts his open asshole directly in the opened labiya and rips a huge fart.

Ammonium Sulfide in a glass bottel that when broken can really clear a hallway or classroom. Best used in the doorway of a classroom. When using it remeber to keep mum because it usual results in an in school suspension.

Little harmless glass containers that release a foul egg-like odor when broken. For best results use inside where there is an abundance of people.
Warning-Do not use at your job site, unless you want to be suspended and sent home for pending investigation.

When you fart so bad that you feel like you want to die

The act of giving someone a Stink Bomb involves quite an elaborate scheme. First, you wear the same pair of underwear for at least two weeks straight. It is important that during this period you do alot of aerobic exercises to really get your stinky-ass juices flowing. Also remember, the longer you wear them, the stinkier the bomb. Next, you choose a victim. Your mortal enemy is usually a good target, but anyone will work. Finally, you wait until the victim is at their most vulnerable (during sleep is always a good time) and rub the soiled underwear all other their mouth and nose.

A sexual act in which the male gives anal sex to the female, then farts in her mouth, then sticks his shit covered dick into her fart filled oral cavity.

When someone goes in a room and they smell so bad, they stink up the room.
