What is it that makes a culture unique? How are whites, blacks, Asians, or whoever different from everybody else? What tastes, interests, and concepts define an ethnic group? And is there any way to make fun of other races in public and get away with it?

We selected 526,000 OkCupid users at random and divided them into groups by their (self-stated) race. We then took all these people's profile essays (280 million words in total!) and isolated the words and phrases that made each racial group's essays statistically distinct from the others'.
