This is an ass that is caused by years of sitting in a desk and not going to the gym to squat and deadlift. You ass becomes 4 foot wide and only sticks out a few inches. Looks like a pancake and is why people start wearing suspenders to keep their pants up. It's not because the gained a bunch of weight. It's because their is no ass to hold up the pants anymore.
Bob just retired today. Company gave him a gold watch but desk jockeying for 30 years gave him chair ass. I don't think a belt will keep his pants up anymore.
