A really bad musician. Someone who lacks technical proficeincy on their instrument, as evident in by the music on thecrumbums.com
That guitarist is a real crumbum. He is so out of tune it sounds like he is trying to be experimental

Get the Crumbummug. A crumbum searches the carpet around an area where drugs were done. Finders keepers for what that days crumming yields. Mostly for meth or other crummable drugs...aka..green pot, white coke, black dab, any pills of a variety of candy colors.
