A fatass is someone with overlapping lovehandles, multiple chins apon chins, and man tits that are triangle shaped due to gravity. They never want to get up, unless food is offered, and there fat giggles when they breath, walk, and talk.

A fat bitch. So fat they cant even see their penis anymore. Someone who the opposite sex is ASHAMED to be seen with. A large corpulent person with sausage fingers and a fat mush face.
