The term originated in the Ozarks, and originally derived from when a man would slaughter a hog and discover a (surprisingly) thick layer of fat (or lard) between the meat and skin, which would then be able to be rendered off and used in cooking throughout the coming year.
When a person was to have something that comes into their favor they were to say that "they cut a fat hog in the ass".

A common term is fatty-acid. fat
It means "tub of lard"; it's a derogatory term for a fat person.
In the days when brine was added to barrels of meat, it had a hardending effect on the fat. It was still edible, but it took considerable chewing. So, to "chew the fat" has come to mean to talk endlessly.
