Dirty Mushroom

When a guy takes his hard dick, after having anal sex and swings it as hard as he can, hitting a person (hopefully a girl) on her cheek with his penis. If done correctly it will leave a mushroom imprint for several minutes with a lasting red spot afterwards and a nice brown mushroom stain.

That stupid bitch pissed me off so I stuck it in her ass and then gave her a nice Dirty Mushroom

Mushroom Fart

A fart so concentrated and large in magnitude that it explodes through your pants and Fus-Ro-Dah's any object within 200 feet, leaving a dangerous amount of fart radiation on the area for years which gives people asskemia.

1. Did you hear that Josh let out a Mushroom Fart on his date last night?

2. In 1945, two obese Americans Mushroom Farted in Hiroshima and Nagasaki and gave many Japanese people asskemia.

Mushroom

When a girl's engorged labia pops out the side of her shorts or panties, it resembles the top of a mushroom.

She was dancing on the stage in her short shorts when her mushroom popped.
