1 definition by JThomas

A young woman, often under age, who will do anything to get closer to a person of high status, such as an up and coming rap star. They will often resort to sex but can use other methods such as obsessive research and knowledge concerning the "likes/dislikes," habits, pet peeves, and other trivia concerning the idol.

Originates from groupie, but spelled with a 'y' for 'young', signifying that the groupie is underage or younger than the idol.
