I love pizza! I am actually a pizza snob due to the fact that I grew up in the NY metropolitan area. 
Then I supposed you will turn your nose up at the idea of frozen pizzas as opposed to fresh, pizzas such as DiGiorno.
Eh, since I moved from there, I have learned to tolerate some frozen pizzas. When did the pizza first come to fruitation?
The earliest recorded usage of the term to refer to food was in the 10th century, no surprise, from a small Italian town called Gaeta.
