Any and all douchebaggery associated with the use of a guitar, including, but not limited to, (a) whipping one out at a party, (b) playing an overwrought, attention-seeking guitar solo for no reason other than you feel like dominating the stage and are a hopeless fucking douchebag (see: hair metal), owning a flying V - especially for reasons of irony. Especially then.
"Yeah, I made it out to see that Metallica cover band. 5 minute impromptu guitar solo at the end of One. Buncha fuckin' guitarbage, you ask me."
"What is he doing, playing 'Major Tom' in the living room? Total guitarbage. Its funny, I guess, but what a douchebag."
