guitarsehole 

An individual, usually a male, who believes that his skills as a rock guitarist entitle him to behave in questionable ways towards others. His sense of self-importance is turned up to eleven, which makes him a less than ideal long-term dating prospect, dining companion, or roommate. Often an emosogynist in his interactions with women, the guitarsehole fares no better with men as he believes that arguing the merits of tube versus transistor amplifiers makes for engaging party conversation.

1. "I used to live with that guitarsehole. He spent more time on his hair than on washing the dishes, wouldn't shut up about the math rock band he had in high school, and was always trying to figure out why he couldn't find a smart enough woman to date."

Guitarsole 

a guitar player with an enormous ego, or is very annoying/rude/petulant the word is a portmanteau of the words 'Guitar' and 'Arsehole'
not legally permitted to name anyone in particular but most 'guitar gods' are Guitarsoles at some point in their careers, I imagine.

After the gratuitous 22 minute solo in which several Stratocasters were burned, knocked over and smashed, he raised his arms in mocking triumph to the crowd - of 9. what a wanker, He's such a Guitarsole its unreal, its only the pub down the road, not the Hammy Odeon!
