two and a half rotations (a nine-hundred degree turn). usually this is done as a trick on a skateboard, bmx bike, or with in-line skates. if you're really insane, you'll pull it off in a car.

an extremely difficult trick done on a skateboard where you do a mute grab and just spin backside until you don't even know which way is up. it's actually performed by adding a 540 to a 360; you have to wind up for the 360 while spinning the first 540. people don't realize how insane it really is.
