What you get when a whole bunch of people race around on their asses. Okay, not really. They just use stopmotion.

The song most often associated with butt racing is "Speedy Speed Boy" by Initial D.

when a whole bunch of people sit on their asses and race.
It can also be just one person.
Butt Racing originated from YTMND, using a stop motion technique.
-We were butt racing in the park last week, and it sucked. Jay couldn't hold the camera steady, and it shaked out of control.
-Dude, use a tripod next time.
