It is difficult to give a precise definition of a hipster, because hipster culture is a "mutating, trans-Atlantic melting pot of styles, tastes and behavior[s]."[3] One commentator argues that “hipsterism fetishizes the authentic” elements of all of the “fringe movements of the postwar era—Beat, hippie, punk, even grunge,” and draws on the “cultural stores of every unmelted ethnicity” and “gay style”, and “regurgitates it with a winking inauthenticity” and a sense of irony.
