Top Definition
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."
