Someone who wishes they were the lead singer of a band. Thus causing them to over compensate by singing loudly in the car, hogging the microphone, or bringing their own song selections to karaoke night.

They also feel like they have the necessary ability and talent. However, they have no training and can play no instruments, but feel like being a frontman would be easy to do.
