Examples of subcultures include bikers, Mormons, Trekkies and bodybuilders. Teen subcultures are referred to as cliques. Since the term refers to a smaller culture within a culture, all groups of people with similar interests, customs, beliefs, professions and backgrounds can belong to a subculture, according to education site Chegg.
It's possible to belong to more than one subculture. For example, a member of Alcoholics Anonymous who is also a body builder belongs to at least two subcultures. One subculture includes the AA organization and all the people who attend meetings and subscribe to the AA philosophy, and the second includes bodybuilding enthusiasts.
