The homosexual act of rubbing the tip of ones penis against the tip of another man's penis for the purpose of sexual pleasure.
Ken took Ben home after meeting at The Manhole. They were so aroused in each others presence that they whiped out their erect cocks and started mushroom smashing until ken unleashed his man paste all over Ben's hairy chest.

Get the mushroom smashingmug. This is a sexual innuendo for reference to a man's erhmm member...in particular this refers to a rather downsized one at that.
Some people find as a reference to stoners or druggies, but in reality they aren't the smartest fucken cookie to think that...it is a new aged reference and is compliments of the innocent minded, dear friend...
Enjoy this new an innovated word

Get the mushroom hatmug. When the head of a man's penis is clearly visible through his pants. The male equivalent of a camel toe.

Get the mushroom toemug. 
Me and my girl haven't seen each other in forever so I've been jacking off a lot. Last night she pulled down my pants and when she saw my dick she sang the Mario theme, it looked like a Mushroom Tip.

Get the Mushroom Tipmug. A variation of teabagging where the bagger first marinates his undercarriage in a viscous substance such as barbeque sauce or ketchup. The goal is to leave a mushroom shaped mark on the victim.
