A person, generally in their late teens or early twenties, who believes their music is far superior to yours, not due to musical quality, but simply due to the fact that their music is obscure and no one else cares about it. Usually, their music is shitty, and they will force you to listen to it. If you tell them their music is shitty, they will get really angry at you, feign a look of indignation, and just call you an idiot. They also like coffee, simply because they think it makes them sophisticated.

Normal Person: Hey, can we turn off this cd and switch it to the radio? I'm not really into the Himalayan monk chant combined with a two man band that plays didgeridoos, harpsichords, and the honky tonk.
Indie Bitch: Eww, of course not! That music is so terrible. It's all just corporate garbage and it all sounds the same. Try to have some creativity, dumb ass! (Drinks caramel macchiato)
