Jesus freak was originally a derogatory term applied to those involved in the Jesus Movement of the 1960s and 1970s who were often considered overzealous in their passion for Jesus. Perhaps its most well-known usage was in the lyrics of Elton John's song "Tiny Dancer". The term has recently been used frequently by Howard Stern and Ted Turner. However, it is also occasionally used today by Christians, especially Christian youth, as a positive term to let others know that they are not ashamed of their belief in Jesus.
