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.
