what kind of pizza is you

I'm the second one

I am the concept of a second pizza. Pizzas are great and all; they taste great, and are easy to eat. In this day and age, ordering pizza is easier than ever, thanks to the internet. Anyone can order a pizza.

But when it comes to social gatherings, a single pizza is never enough. Two people can share one pizza, but what about three people? At some point, a second pizza becomes a necessity - a second pizza turns a party into a pizza party.
