"Knob shower" is the term used for a shower that you take exclusively to wash away your knob cheese, if you happen to have some.
Guy 1: My g, what's that smell?
Guy 2: Ah mate, that's my knob cheese. Sorry.
Guy 1: Go have a knob shower!
Guy 2: Ah mate, that's my knob cheese. Sorry.

Pretending to shotgun a Coors Light with your friends and blowing into the beer can while pointing the can opening towards your intended target. Your friend should be covered in an ice cold shower of beer.
Instead of shotgunning the beer, he turned the beer towards his friend and gave him a rocky mountain shower.

When a person climbs into the ceiling of a bathroom and cuts a hole above the shower recess for their erect penis to hang through and then ejaculates on the next unsuspecting user of the shower.
He was mortified to find his roommate had once again given him a Bomber's Surprise Shower when entering the shower to prepare for work. It would take him hours to remove all the semen from his hair.

When a man repeatedly ejaculates in the shower and it hardens over time and forms a shower clam. It is like a free textured floor!!
