A means by which people-wheather you agree with their opinions or not--cleverly show off their opinions that the rest of us are too shy to tell. My favorite says: "Don't like my driving? Dial 1-800-EAT S**T."

Get the bumper stickermug. The tendency of a pedestrian preoccupied with another task (e.g. talking on a cell phone, fiddling with a portable music device) to veer left and right across the sidewalk, unknowingly blocking faster-walking pedestrians attempting to overtake them.
So named for the similarity between the perpetrator's movements and those of a bowling ball in the eponymous ten-pin bowling variant, in which the lane's gutters are blocked by bumpers to prevent gutterballs.

Get the bumper tailingmug. When a person needs to take a crap, but no toilet is readily available. You drop your pants, set your coccyx-area down on the bumper of the nearest car, and crap (mostly) onto the ground.
This maneuver is usually performed by a "SF Mission Hipster", after he/she has consumed several Pabst Blue Ribbon beers. Bonus points if the car is a symbol of gentrification, such as a German compact sedan.

Bro #1: Dude. come check out my sweet new BMW 418!
Bro #2: Brah, it looks like someone pulled a bumper dump on you, and missed a bit.
Bro #1: Dude. Lets go back to the Marina and drown our sorrows at Bar None with some beer-pong! Did you bring the rufees?
Bro #2: Brah, I wouldn't have it any other way. Let's go crush some beercans against our foreheads!
