look up any word, like blumpkin:
 
1.
Fake urban car or truck accessory. Hung under the back of a truck or car simulating human scrotum. Usually small and cheap imitations of truck balls. Supposed to indicate a masculine truck, but really indicates a cheapscate, or a n00b is the owner. A put-down. Indicates a wanna-be, or someone trying to join the fad, but screwed up.
