The blog "Stuff White People Like" is a self-parody of yuppie culture that is pretty funny. As is quickly apparent, it is not about all white people -- in fact, the current item on the blog, #84 Tee-Shirts, cites "Getting Lucky in Kentucky" as unacceptable because it is worn by the "wrong kind of white people." But that, itself, is part of the parody -- the kind of white people who are self-conscious about being white, and parody themselves because of it, are drawn from the yuppie end of Anglo culture.
And the #1 thing white people like? Coffee.
