Groupie

The term groupie is a (primarily American English) slang that refers to a fan of a particular musical group who follows the band around while they are on tour or who attends as many of their public appearances as possible, with the hope of meeting them. The term is usually derogatory, describing young women who follow these individuals aiming to initiate a sexual encounter with them or to offer them sex ''quid pro quo''. The term is also used to describe enthusiastic fans of athletes, admirers of public figures in other high-profile professions, and gold diggers who seek to marry up into the high society by offering themselves as free escorts for celebrities and high-net-worth individuals who attend house parties, functions and yacht tours.
