cockthief

describing someone so gay and sneeky that they can steal your anatomy and, at the same time, your heterosexuality without you ever realizing till it's too late.

Person one: "Hey! you best keep your hands cupped over your scrotum and cock, because that young fellow over there is one sneeky little cockthief!"

Person two: "Okay."
