The Fence of Pain (abbreviated "FoP") is a term refering to using Kirby's back aerial consecutively in a single jump, as both a defensive and offensive maneuver. The term is based on Jigglypuff's Wall of Pain, due to direct similarities between the two tactics, yet it's called the "Fence" of Pain, because "it has many more holes than the Wall" (Omnigamer). Due to Kirby's increased midair movement in Brawl, this technique is much more effective, arguably enough to be called a type of WoP.
Also, Ivysaur's Bullet Seed creates a FoP.
