Valley girl

Valley girl is a socio-economic stereotype depicting a class of women characterized by the colloquial California English dialect Valleyspeak and vapid materialism.

The label originally referred to a swell of upper-middle class girls living in the early 1980s Los Angeles commuter towns of the San Fernando Valley, but in time the term became more broadly applied to any woman or girl—primarily in the United States and Canada—who engendered the associated affects of ditziness, airheadedness, and/or greater interest in conspicuous consumption than intellectual or personal accomplishment.
