How do you define culture?

Culture is the doings and traditions of a society that make up an individual. A personal culture is the combinations of cultures in which an individual grew up in. For example, one's personal culture may be made up of Puerto Rican heritage and traditions and New York City, Bronx doings. Culture is extrinsic. It's not something that someone will be born knowing. For example the behavior one is actually born with may be acceptable in one culture, but in another is must be learned to do the opposite.
