In the white wolf live-action roleplay (larp) or tabletop game "Vampire: the Masquerade," FAP is an acronym for the combination of three extremely potent vampiric combat powers: Fleetness, Aegis, and Puissance. The game is designed such that most characters should never possess all three powers, but in practice many gamers/larpers who desire excessive power will find ways to acquire them all (see powergamer, and some of the definitions under twink).
