Look up metal man and add this... Those who take it to the next step and begin to mimic their fav metal band by taking up the guitar and playing there music for over 6 hours a day trying to perfect the same style of music.
A place where you might go to buy music equipment and have some jerkoff call you "Boss" (and other things) one too many times after you bought your stuff. Thus making you want to grab a guitar and ram it down the punk's throat. And then save what's left of the guitar for the guy up front who checks your bag best-buy-style.
