I knew "chuffed to bits" (British) and "shawty" (American). Shawty, or shorty, is fairly known in US hip hop culture. Never heard any of the other ones.
Some US pop culture trivia for those who are interested-the song Ellen was quoting from during the "shawty" discussion is called Low, by hip hop artist Flo Rida.
