Indie Snob
A person, usually a self appointed "Musician" who particularly entertains the idea that their taste in music is really different and unique to everyone else's, and is usually convinced that any band who experiences commercial success has "sold out", even if said fan may have previously claimed to have liked that band before their peers.

Putting three Indie Snobs in a room together is usually dangerous and somewhat anti social, as they will continually argue with each other over who liked a band first.
Regular John: Mate. Muse are playing in a few months, I haven't seen em yet. Wanna go?

Indie Snob: Bitch please, I saw them years ago when they still played in bars.

Indie Snob #2: Yeah? I went to High School with one of them.

Indie Snob #3: Pretty sure I was there watching their grandparents have sex, you're all newcomers.
