The lower bulge of fat that protrudes below the belt line on obese women though men can certainly display a large poofdie as well. Often accentuated by a long zipper or pleats. Sometimes there is a single poofdie, or a double-wide poofdie. The creation of it is often the result of pants pulled up way to high, giving the illusion of a very small torso since the belt is often in contact with the breast/chest area and the belt is way above the belly button zone.
Ralph's a poofdie lovin chubby chaser. If the chick has a large poofdie, he's all over it.
