The act of parking a car at the top of a parking lot on a hill and releasing the parking brake so that the car slowly rolls down the hill, confusing the shit out of any one in the lot. The steady control of the parking break ensure a slow and steady speed.
For extra confusion, put down the seats down so that no neither you, or any of your passengers and visible to the people outside.
Tip: works best at night
