loop it
When you're doing a wheelie on a bicycle or motorbike and the back wheel slips out from underneath you. Also less commonly known as a loop out
The back brake is the integral part of the long-wheelie, so make sure your brakes are powerful enough to bring you to a skidding stop when used at high speeds. Anything less and you’re liable to “loop it,” which means falling backwards and having the back wheel shoot out then your back slaps onto the pavement or road. While doing the wheelie you should have 1-2 fingers on the brake lever.
