Mushroom Stabber 

Term used when a guy does a girl thats so young all he can get in is his mushroom tip(aka his dick head). You have to be really desperate or really sick or both to want this to happen.

mushroom-cap 

When two people are having anal sex and the person pitching pulls his penis out of the other one's rectum to find a large glob of santorum hanging from the end of his rod.

I probably should have expected it because we'd gone out drinking all night then eaten that greasy midnight pizza over at Cosmo's, but when we got back to the apartment she let me do anal on her and when I pulled out of her she left a big mushroom-cap hanging off the end of my rod.

inside out albino mushroom dalmation 

Similar to an inside out mushroom dalmation, but the sperm is blown onto a white article of clothing, giving the albino dalmation effect. Must be performed while high on pot.

"I finally talked Jill into letting me give her an inside out albino mushroom dalmation on her favorite white sweater.....damn we were so baked!!"
