Scott Westerfeld is a young adult author who wrote a brilliant trilogy of dystopian fiction: Uglies, Pretties, and Specials. In it, the society is split (into Uglies and Pretties, no less): the Uglies are not attractive but retain their intelgence and the Pretties are attractive but rather stupid. The Pretties have a very distinctive slang, based in the adjective-verb construction, like sad-making. Also, they refer to people being stupid as "bubble heads," a fantastic phrase I think should be introduced into modern English.
