A superficically dumb valley chick, with no common sense what so ever. Usually of white race, rich, and pretty. Often uses words such as "like", "oh my gosh", "oh my goodness", "that is like so not cool at all", "dude".
Oh my gosh, I like so want to go to the mall dude...
I am a preppy bitch, not a ditz .. hehe get that straighten out dude!
Someone who isn't necessarly stupid, they just lack good judgement in their decisions and good common sense. Most of the ditz girls I've met have been pretty, I guess they think pretending to be stupid makes them sound cute.
The boys don't care that she's a ditz, they seem to buzy looking at her chest.
