bumper dumper

When two cars are parked close enough together that you can rest each a butt cheek on each bumper to take a shit.

Oh man! If i can't find a bathroom i'm going to have to pull a bumper dumper.

bumper nuts 

Prosthetic testicles used to adorn the oversized vehicles of those who think very highly of themselves.

They aren't entertaining and they don't make you look cool.
They are contrived and make you look uneducated.

Jeff hung a pair of bumper nuts on his Tacoma.
Jeff's truck only shuttles him to and from work and the grocery store.
He did take it off-road once, and ironically his ground clearance was insufficient to prevent a rock from removing a portion of his oil pan and wrenching the faux balls of his otherwise unused trailer hitch.

bumper fucker 

(n). See tailgater or bumper rider. Anyone driving so dangerously close to another car's bumper that the driver in the front car cannot see the tailgating car in the rear view mirror. The driver who bumper fucks sometimes often does so and then turns off on a side street. This is called bump and dump. Bumper fuckers who tailgate, then drop back then tailgate and drop back, is a daredevil tactic known as clipping and dipping.

Hey Ron, would you slow down? I can't Janet, I got a bumper fucker in back of me!

Bumper Chodes 

Noun: An incident involving two chodes in which said penises, either intentionally or through sheer coincidence, bump into each other. The chodes do not have to literally bump and repel; merely rubbing against another chode constitutes a bumper chode event.

Please take note that this definition utilizes the proper (and more comedic) meaning of the word "chode," that is, a penis wider than it is long.

I got real drunk and played a game of bumper chodes with Ryan last night.

I was trying to get into the bathroom at the club when I inadvertently played bumper chodes with some random dude.

bumper sticker activism 

To tell the world what they should be doing and what you think by plastering your car with bumper stickers to that effect.

Jim: That "Keep Tahoe Blue" sticker is really making me wonder how to keep Tahoe blue.
Mike: Yeah, Berkeley is full of bumper sticker activism. Too bad the sticker's on a Ford Expedition, since keeping Tahoe blue involves reducing emissions.
