poopie mushroom

I was pissed at my girlfriend so I stuck my dick in her butt and gave her a poopie mushroom.

Mushroom Top

A term to descibe the image of a woman's flabby calves spilling over the top of a pair of boots. Similar to the term muffin top, except on one's legs.

Did you see her mushroom tops? Her legs barely fit in those boots. Her calves were pouring out the top.

"mushroom haircut"

A popular caucasian men's haircut in the early 90's that got its name from the overall shape of the doo. This haircut did not survive the test of time and is frowned upon today. If you see anyone currently rocking this haircut you might want to give them the memo. There was a brief hybrid version that surfaced about a year later, in which the underbelly of the shroom was shaved. It was popular amongst the alternative and punk kids.

Hey fun-guy, you might want to shave "mushroom haircut".
