1. The act of shooting squinty-eyed dirty looks at the guitar player in your band (which he, unfortunately never see's because of guitar face!) when he decides to solo LOUDY through the entire song in his usual autisticway.
The inevitable state attained when a normally skilled guitar player loses said skill after over-imbibing in alcohol and/or other narcotics, and can no longer play a normally easy song or riff.
Note: normally this is used only by the guitar player him/herself, as those in the vicinity are likely also too inebriated to notice the guitardedness.
1)Fuck! I'm guitarded. 2)I'llplay you this song unless I'm already too guitarded.
A guitar player that constantly plays unimpressive scales onstage, calls it soloing but really it's just wanking. Usually leads into ten minute "improvised" guitar "solos" of the player just going up and down scales. Musical masturbation. Even though the typical guitar wanker is not very creative, non-musical audience members may be very impressed by it all, but other musicians are not.
Guitar wankers can often be found in bar room blues bands and new bands with short set lists. Heavy Metal guitarists in general are wankers. Neil Young is a prime example of a guitar wanker.
