Velvizza
Pizza with provel, which seems endemic to St. Louis, thank god. A blend that for some reason supplants mozzarella, provel often gives an orange-and-white topping that is redolent of Velveeta in both look, taste(less), and texture.
To waiter: "Skip the provel and bring on the REAL cheese, my good man. We're in no mood for Velvizza, and there's no reason for you to die tonight."
