Where you jab your hand up someone else's ass, but then, quickly forming your hand into a fist before it hits the anus. The resulting impact kills the person instantly. Ideal for a KO move.
Inspired by the term "anal death punch" and the band "Five Finger Death Punch" (an amalgamation of each phrase).
*InsertNameHere* gives person B a five finger anal death punch. B drops dead almost immediately.
