The Logical Fallacy of Peer Pressure occurs when pressure is brought to bear by actions or speech to squeeze you into the same mold as the pressuring people. Peer pressure differs from appeal to the people/bandwagon in that peer pressure works based on a desire to fit in where appeal to the people/bandwagon works by appearing to prove a truth when no real proof has been offered. Peer pressure doesn't care about truth. It cares about fitting in and being accepted.
