I can tell you that "asses hanging out of pants," for some electricians, plumbers, or other "portly people" is a direct result of having pants that are too small. It is often difficult to fit pants properly when one has a "large over-hanging belly." The belly can be several inches larger than the underlying abdomen... the pants can tend to fall down without proper support. I use a belt that has no holes... You can keep pulling on the belt to make it tighter... even that doesn't always work. My wife gets mad when I get larger, and need to buy new clothes. Heck, it's becoming almost impossible to find my size in Wal-Mart or KMart. If the pants are not large enough to properly cover the belly, then they sometimes don't cover the ass correctly. Then you see those ugly, sometimes hair asses sticking out.
