http://en.wikipedia.org/wiki/Chavs
(female chav), Charv or Charva) is a slang term in wide use throughout the United Kingdom since 2004. It refers to a subcultural stereotype of a person with fashions such as flashy "bling" jewellery and counterfeit designer clothing; an uneducated and uncultured background; a tendency to congregate around places such as fast-food outlets, bus stops, or other shopping areas; and a culture of antisocial behaviour and violence.
