Cumstopper 

A slut who gives you hopes of a good fuck, only to cancel on you last minute causing the excess cum produced from anticipated sex to be bottled up. This leads to balls swelling to the size of a grapefruit.

Guy1: "Bro, my balls hurt from hanging heavy. My slut bailed out on me again."

Guy2: "That slut's fucked up."

Guy1: "Nah bro, she's cool. She can just be a real cumstopper sometimes though."

"Nah bro is pulling a cumstopper you were just dick riding him but now you finally hopped off"

"No you cumstopper"

cowstopper 

Someone with a protruding mandible, full of grotesquely crooked teeth. Usually the lips are not large enough to hide, e.g. resembling a cowstopper on the front of a train.

Did you see the cowstopper on that fool? I'm gonna go push him over to the train tracks.

cumsopper 

the undersized well manicured mustache that gay men have...they use it to sop up the cum that is left on the head of the cock

Woman : What is your opinion about Bruce? Do you think he is gay?

Man : That cumsopper is a dead giveaway baby.
