Groupie

A groupie is a person whose devotion to a person (usually a celebrity, especially a rock and roll star) approaches the level of fanaticism often seen with destructive cults.

Groupie is derived from group, meaning a musical band, but now has more general application.

Female groupies in particular are known for a long-standing tradition of being available for, and willing to have, sexual intercourse with celebrities and rock stars. While only a small number of groupies are truly promiscuous in that they are willing to trade sexual favors for attention, the tradition of "rock and roll groupies" continues to the present day, contributing to the image of the rock-and-roll lifestyle as one where sex and drugs are readily available at any time.

The 1999 movie, Almost Famous, explored the lives of rock beat writers, rock and roll stars and their groupies.

Another 1984 movie This is Spinal Tap, grossly satirised that same lifestyle.
