A swerve is a professional wrestling term in which a wrestler suddenly turns against another wrestler who is supposedly his friend. This is a start to a feud and a storyline between the two wrestlers that would explain the reasons for the swerve. While the purpose of a swerve is to surprise the fans, poor booking may result in some very predictable or senseless swerves.
