A crustaceous creature contracted after stealing an underaged girl's "P" at camp. You may think your cool at first until you begin to take on crab-like characteristics. Bubbling at the mouth, a redish coloration of the face, and even super-human aggression. The only way to rid these from your nutz is to stand on the bow of a boat while making a thrusting motion into a high powered fan.
John thought he was the shit after being called a pedifile at summer camp until he realized he had crabs all up in his ass.
