I came across this site recently: Stuff White People Like. It is HILARIOUS. Just as an example, here is an excerpt from #91 San Francisco (close to my heart being from the Bay Area):
Much in the way that white people in Brooklyn feel a strong and unfounded connection with The Notorious BIG, white people in San Francisco feel the need to identify with rappers from the East Bay. Interestingly enough, the further they venture from San Francisco, the stronger their need to represent their region.
“Oh man, I went to the show last night. So hyphy man, so hyphy. You should come by some time and we’ll ghost ride the Prius.” When you are presented with statements like this, the best response is to say “Berkeley is close to Oakland,” and the white person will likely nod and throw up some sort of west side hand sign.
