obesitize
To get so fat you look like a donut exploded in a pants factory. Usually happens after eating 12 pizzas and crying because you can't fit into your jeans anymore.
I obesitized after eating 3 whole pies and watching 2 hours of cat videos.
My cousin obesitized so bad he got stuck in a door and had to be pulled out by his uncle.
I obesitized during a pizza challenge and now my pants are a second home.
