a term used in motorcycle road racing. an on throttle slide, usually on the exit of a turn where the rider causes the rear end of the bike to step out or oversteer by adding generous throttle. the rear wheel will spin faster than the road speed and cause the slide. in motorcycle stunting, it is usually called drifting and is at slower speeds incorporating the front brake. the technique is also used, in flat track, motocross and supermoto racing.
did you see him powerslide that turn? yeah he lit up the rear for about 50ft.
