Dung-fu

An ancient martial art combat technique where the hands are brought together in a praying gesture, while the ring and pinky fingers are interlocked, creating a reenforced knife-shape with the thumb, index, and middle fingers of both hands. The hands are brought quickly and tightly to the abdomen, and then violently thrusted forward into an often unsuspecting victim's anus, causing debilitating pain.

A single, well-placed dung-fu neutralized the mugger.
