Professional Wrestling's version of Negative Continuity and Retcon. The unwritten rule states that any events that took place more than three months ago do not need to be considered canon. This creates interesting situations where two wrestlers who were recently at each other's throats are now the best of friends. It also provides a means for the writers to not have to explain radical changes in a character's gimmick (went from a millionaire playboy to a voodoo priest and back again? No problem!).
