fiat

The place between Fat and Average. When you are Fiat it often means you're a little on the chubby side, eat a lot more than you weigh, should be fatter than you actually are, and grab food faster than a snapping turtle.

Andrew is so fiat, he just keeps eating while he should actually be fatter.
