n. a car or other vehicle following too closely on one’s bumper. (A reapplication of the term for a kind of adhesive sign stuck on a car bumber.) I can’t talk now, I’ve got a bumper sticker that’s taking all my attention.
1. exclam. Stop following my car so closely! Don’t follow me so close! Get off my bumper!
2. exclam. Stop monitoring me!; Get off my back! Look, man. I can take care of myself. Get off my bumper!
n. in someone’s face. (Alludes to gold teeth.) He had his smelly face up in my gold ones, so I clobbered him. Why are you up on my bumper, dawg?
