Carioca

Carioca is a Portuguese adjective or demonym that is used to refer to the native inhabitants of the city of Rio de Janeiro – capital of the homonym state (RJ), in Brazil. The original word, "kara'i oka," comes from the indigenous Amerindian language of the Tupi people, meaning "white man's house." It is said that the first Portuguese dwellings in Rio de Janeiro were placed along a limpid stream, which soon got the Portuguese name carioca.
