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”.
Common definitions:
1. To have a monetary gain.
2. To have something beneficial occur in their favor.
3. To have a
raucous time.
