Oh. My. Gawd! If you need me to tell you what a valley girl is, like, then you are, like, SO lame!!
In other words, a self-centered, vacuous, entitled girl from the San Fernando Valley.
A girl from the San Fernando Valley--I live near there but I've never heard anyone who sounds exactly like the stereotype. I think it's an 80s thing lol.
A spoiled, idiotic adolescent female from the southwestern part of the United States, typically rich and white, whose language is insulting to human intelligence.
a girl from the Valley also a movie.
