conformist
Everybody. All that is need be said. It is literally impossible to be "original". No matter what you think of, somebody somewhere has already done it. The people who started each "original" idea are generally labeled as conformists. The crazy kids that sit off in the corner wearing dark clothes with the anarchy shirts are conforming to the "anarchist" mindset, and no matter what they say about conformity, they all go along with it.
anarchist: no way, im not a conformist, im original with my nihilistic views of the world
