Chinese Toboggan
The act of having set doggie style while riding the person like a toboggan down a flight of stairs. Pulling of the rider's hair/arms is also acceptable as to keep injury to a minimum. - I have to credit this phrase to a girl I know who told it to me at the beach one day...
Dude, I gave this chick a chinese toboggan last night and her stomach is bright red from the ride!
