People who listen to bands no one has ever heard of and can be rather cocky. They never call themselves hipsters and deem many things as "mainstream"
Many teenage girls of these days attempt to pose as hipsters through their Instagram and twitter post, but do not succeed.
Girl 1: I'm going to post a picture of my converse with a vintage filter
Girl 2: OMG so hipster! 1!1!2!222!!
Girl 3: I'm wearing an oversized sweater and combat boots, how hipster am I?
