Term used to describe a categorical serial killer of sexual intercourse. This guy will sleep with anything. He'll take it wherever and whenever he can get it. His psychological profile is limited to the simple question: do they have a vagina? He has no regard for his own sexual health, nor that of others. He dirties his glans in the pool of communal poon without a second thought. Has no standards.
Friend J: "Holy shit, I've heard Friend A took home another rotter last night."

Friend J: "That guy's a muffin slasher."
