mushroom club

Military unit (usually) that is constantly kidfoh-ed; that is, kept in the dark and fed nothing but horseshit. These are usually, but not always, "elite" units that will soon (and often) be called upon to do something damn-near impossible, of questionable legality, and with entirely too little training, preparation or equipment. Superiors will then wonder why-oh-why these boys and girls couldn't pull a miracle out of their asses.....

"So, Slick, which mushroom club are you with?"

Puking Mushroom

The Puking Mushroom is when you are having sex with your girlfriend doggy style without a condom and you don't want to cum inside her, so you take out your dick and pop the head in her ass and cum.

I was having sex with my girlfriend last night doggy style without a condom and I didn't want to blow my load, so I gave her the Puking Mushroom and she loved it!

Furry Mushroom

When a girl shaves the mans pubic hair into her mouth and proceeds to give him a blow job, after of which, his helmet is covered in his pubic hair, resembling a furry mushroom.

Oh my god, that girl is crazy, last night she tied me up and gave me a furry mushroom.

mi chang mushroom

During ejaculation continue to stroke the cock with one hand while placing the other hand over the head and rubbing it all around the head until it stops cumming.

When she gave me the Mi Chang Mushroom I couldn't contain myself, I don't think anyone can handle that without squirming all around.
