Somebody who kicks ass at Guitar Hero and makes them think they are good at the real thing but in reality they try to play a guitar like they are a god and sound awful usually blaming the guitar.

Real Guiatrist:"Really? Heres my axe prove it!",
Guitar Her-No:"Wheres the red button, man your guitar sucks!!!",
Real Guiatrist:"LOL You Guitar Her-No!!!"
