In professional wrestling (e.g., WWE, AEW, NJPW), 'kayfabe' refers to the fictional storylines and characters wrestlers portray during performances (e.g. The Undertaker as a supernatural "dead man" or Asuka as a villain who uses "poison mist")
Matches are scripted and pre-determined to advance these storylines, with wrestlers collaborating on planned moves.

Storylines typically involve feuds between characters, such as a custody battle where the winner of the match would gain custody of a child
