chicken bumswing
This was a martial art invented and practiced in my secondary school. Pioneered by Matthew Roche and Jason Walker, it involved opponents (one-on-one or team event) running at each other at high speed, jumping into the air, whilst turning so that the bums of each opponent would clash. The main idea was to knock your opponent off balance in mid-air so that they would land flat on the concrete with a rather loud slap. It was also customary to chant 'chicken bumswing' in a mild Oriental voice whilst in battle.
