Carioca is what people from Rio de Janeiro are referred to as. If you talked to a linguist regarding the term Carioca, they will more than likely tell you it is a Tupi Indian phrase which means "houses of whites" or "white house." This is how they described the homes that had been built by the Portuguese who settled in the country of Portugal. In time, this word was adopted by the Portuguese, and it is what most of the locals in Rio call themselves.
