obesoid
An obesoid is a person so fat they could be a new kind of monster. They look like they came out of a deep fryer and forgot to come back.
My brother is an obesoid. He eats so much he could be a walking buffet.
The obesoid in my class got kicked out because he took up the whole desk.
I told my friend I wanted to be an obesoid, and he said, 'You’re already halfway there.'
