Pizza for plebeians, plebs but made to sound Italian.
Cheese on toast is not to be called welsh rarebit. That is different.
Cook: Unfortunately this is the kind of pizza that you can't eat.
Pest: What! I eat every kind of pizza.
Cook: But I'm making Pizza Plebiano.
Pest: Sounds gorgeous!
Cook: You can't eat it because there is only enough for me. Go away.
