A derrogatory term for a person who believes that they have been reborn, usually through accepting Jesus as their personal favor. Especially applies to those whose born again beliefs are extreme or ridiculous or whose behavior is annoying, for example campus evangelists who are former prostitutes who believe they have been 'revirginated' by Jesus.
