What is Valley Girl? Is is someone coming from a certain area?
It was originally. Beverly Hills I think. It's become slang for an affected, shallow manner of speaking often heard in female teenagers and shallow young women. Think Paris Hilton, Cameron Diaz, yada, yada, yada.
Oh snugs you don't miss a thing! Valley Girls - I think this began in the 1980s - are from one of the "valleys" in California, usually late teens/early 20's rich girls who always say things like "totally." Oh dear I'm not explaining this well...
