subculture definition

A group within a society that has its own shared set of customs, attitudes, and values, often accompanied by jargon or slang. A subculture can be organized around a common activity, occupation, age, status, ethnic background, race, religion, or any other unifying social condition, but the term is often used to describe deviant groups, such as thieves and drug users. (See counterculture.)
