"Street dance, formally known as vernacular dance, refers to dance styles\u2014regardless of country of origin\u2014that evolved outside of dance studios in any available open space such as streets, dance parties, block parties, parks, school yards, raves, and nightclubs. They are often improvisational and social in nature, encouraging interaction and contact with spectators and other dancers. These dances are a part of the vernacular culture of the geographical area that they come from."@en . .
