Etymology: Contrary to popular belief, it has
nothing to do with vehicles.
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”.
