A bumper bitch is the stupid ass mother fucker who gets in the smallest fender bender accident ever on the busiest street in existence, yet proceeds to leave the vehicle parked in the middle of the goddamn road in complete ignorance or in hopes of several thousand cars behind him slamming on their brakes trying to avoid a catastrophic pile-up.
I just got out of the ICU having broken my neck from rolling my mother fucking car while trying to avoid the goddamn bumper bitch hanging out in the middle of the freeway. Next time I see a bumper bitch, I'll slap that fucker's face from my driver's seat as he stares at me in bewilderment with his head through my windshield.

A dusty bumper is the action of falling ass-first into the dirt while ones pants are around their ankles. Common during rowdy outdoor sex and defecating in the woods. If the latter is the cause of the dusty bumper, one may walk away with a rusty bumper.
