look up any word, like bukkake:
 
1.
A person who claims to be a diehard fan of a popular artist, but has only heard the latest singles they released on the radio.

A person who only likes an artist when they begin getting radio play.
Jenny was a poser fan of Fall Out Boy because the only song she knew was Thnks Fr Th Mmrs but she claimed to love them anyway.

Many people don't like when their favorite bands become famous because they attract lots of poser fans, who only like them because their songs are played on the radio.
