Bedroom shredder

Someone who practices guitar in his bedroom with little or no desire to join a band. Usually these types have MAD chops as a result of sitting in their rooms, practicing for hours upon end. Every bedroom shredder gets issued a Washburn, Ibanez, or Petrucci signature guitar (the official weapons of choice of all able-bodied teenage males) right after purchasing a web cam and completing YouTube shred army basic training.
