Someone who orders standard Italian food (pizza or pasta) whenever they go out to eat, and complain when they go to a restaurant that doesn't offer it. These people are known to be unadventurous, or, in other words, boring.
Man, we went to the most incredible Asian restaurant last night but she still managed to order a penne pomodoro. She's such a bloody pizzaterian!

A person who only eats pizza, rejecting most other foods.
Man, that kid rejects most food put on his plate, but he scarfs pizza, he must be a pizzaterian.
