SNAGing is a verb, meaning 'to mutilate pearl jam songs'; it was made popular in the late 90's by a rag-tag quartet based out of Vancouver named SNAG. These four 'musicians' took pleasure in playing pearl jam songs out-of-key and often improperly timed, much to the dismay of their neighbours, friends and associates. Despite repeated efforts by music industry big-wigs, the four refuse to reunite. The god-like status they acheived at the peak of their meteoric rise apparently soured them to the limelight.
