A kind of joke that starts with something like "Okay, so these two black guys walk into a bar, and the bartender..."
A Mexican, a black, and a white guy are in a bar having a drink when a good-looking girl comes up to them and says "whoever can say liver and cheese in a sentence can have me". So the white guy says "I love liver and cheese." she says "that's not good enough." The black says "I hate liver and cheese", and she says "that's not creative", and then the Mexican says "liver alone cheese mine."
- that's what you call a racist joke.
