The act of frantically hammering at the buttons on a controller or arcade console. In a Fighting Game, the idea is that random button-pressing will somehow unlock a super-powerful attack or result in a series of attacks that will overwhelm your opponent. As you may presume, this is the act of an amateur, and is derided by "serious" players. Only someone completely unfamiliar with the game or their chosen character has to resort to this tactic. Of course, it can be a bit infuriating for these "serious" players when, due to some poor design decisions, their skillful finesse on the joypad leads to them getting walloped by someone who just taps the "punch" button so fast they can never get a move in.
