Can anyone tell me a good (mildly or severely) derogatory name for a musician, or specifically a guitarist? In Polish I'd use szarpidrut, literally string-puller, but I'm stumped for an American English equivalent. EDIT: I need this for a description of a room, and I don't want to say "there was a guitarist tuning his guitar by the wall", but convey the speaker's contempt for the profession.
If it helps, the speaker is Paul Smecker from Boondock Saints, and the guitarist in question is played by Antonio Banderas ^_^
EDIT: Thanks everyone - I went with axe-basher. Results available here if anyone's interested :)
