Wall of Pain

Wall of Pain (abbreviated "WoP") is a Jigglypuff strategy of constantly barraging the opponent with aerial attacks, while exploiting Jigglypuff's horizontal air maneuverability. Each attack should go forward in the air, then once you hit your opponent, back to where you started. This allows for quick attacks and keeps you out of range from any retaliations.

Tetsuya and AOB were the earliest prominent users of the technique, and they are largely responsible for its widespread use (see PuffStuff). The term "Wall of Pain" was coined by Smash World Forums administrator and retired smasher Amorasaki, a longtime friend of AOB. One of the most famous examples, commonly demonstrated by pro smasher King, is the use of Jigglypuff's multiple back airs to juggle an opponent off the stage, horizontally.
