Obesiate
When a group of fat people hang out. Or if one person is so fat they call them an obesie. It's like being in a group of people who all failed at dieting.
My friends and I are the obesiate squad. We eat like we're going to die tomorrow.
My cousin is an obesie. He eats so much he could bench press a cake.
The obesiate gang is hanging out. They just finished a whole pizza and a bag of chips.
