stinksty nine 

A play on the classic 69, both parties place their noses against the bootyhole of the other. Each person simultaneously farts and inhales the fart of their partner, until both parties climax.

Dude, my girlfriend and I decided to stinksty nine last night, and I threw up right in her butthole.
