Mushroom cock

This is usually used as a joke when talking to friends. The penis is normal in shape untill one notices the end, where it has dramatically bulged into a mushroom shape. To get a mushroom cock one can use a lacky band so that the circulation builds up and the head swells. This person usually needs therapy or has a hot date.

Dewy: Sup bro whats been happening?
Jero: Nothing much. Got a huge pain in my penis, it's throbbing like hell. Lisa wont want to see me tomorrow.
Dewy: Hahaha, mushroom cock syndrome? Take that lacky band off the shaft so it doesnt throb you idiot.
Jero: It's not the lacky band, i took that off ages ago. This is prob from the STD i got from the rank chick that thought i had a Watermelon cock.
Dewy: Fuck!! Dude seriously you gotta stop worrying about the shape of your cock it isn't healthy.
Jero: Yer i know but the hoes love it.
Dewy: No they dont.

Shitaki Mushrooms is what you say in place of the word "shit". It often keeps you from getting in trouble at school and other places where "cursing" isnt neccesarily accepted!

mushroom mark

The red outline on a persons body (usually forehead) left by a heavy slapping of a man's penis. This is the result where said victim has ran their mouth too much, didn't give head, or passed out drunk.

I gave that bitch so many mushroom marks that her forehead looked like the background of a smurfs episode.
