Top Definition
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."
