When a song is on the game Guitar Hero/ Rock Band, and everyone gets the game, therefore solidifying its popularity and making it a cliche to listen to it anymore.
Bill- Have you ever heard this song before?
Jim- Oh yeah, it was on Guitar Hero!
Now it's awesome!
A douchebag, usually a freshmen, who brings his guitar to school even though he sucks and can play one song (most likely the beginning to stairway to heaven). Said person for some fucking reason get's tons of attention and popularity because he's "a guitar player" always completely frowned upon by people who can actually play guitar. This can also be a "Beach guitar douche", "Camp guitar douche" "Mall guitar douche" etc.
Dude Michael, you see that fucking guitar douche over there? Why are there so many at school today, he fucking sucks so bad!
A person who brings their guitar to a house party, gets drunk, then proceeds to play said guitar in order to try and impress someone. This person is usually a gigantic douche and should be treated with a slap to the face and removal of guitar privileges.
Guitar Douchbag is the guy who goes to a party and pulls ALL the tail due to his guitar playing “skills.” So say some guy is there and being all charming and telling jokes and is the life of the party, then guitar douchebag comes in and sits down in the corner with his guitar and starts strumming a few notes, then goes into full on song with lyrics. You don’t even really need to know how to play well. You really only need to mix in like 3 chords, you can even make up the song on the spot. The panties will drop faster than the eye can see.
I was the life of the party, everyone was loving my jokes, then guitardouchebag came in and stole all the chicks right from under us.
