Obeastity
A person so fat they look like they could scare off a bear. They move like a grumpy elephant on a sugar rush.
My mom is an obeastity. She walks into rooms and people run out screaming.
That man at the gym is an obeastity. He lifts weights like they are made of cake.
My cousin is an obeastity. He eats a whole cake and still has room for a whole pie.
