Anybody who doesn't give a shit about what other people think or want to pressure them to do. Getting a lip ring and having a cigarette in your hand does not make you a non conformist.

Preps can also be non conformists because they don't give a shit what other people think, they will live their life and they don't care who tries to make fun of them.

If you give that a thumb down just because you think ohh preps are conformists, well then sorry to say you are a conformist! lol
