A "hog's bait" is a large meal that one has consumed (generally enough to "bait" a hog and catch it). A "hog's bait" is also when a person has had enough of a certain situation.
Generally used in the deep south.
Damn that was a good buffet. I ate a hog's bait.
I tell you what, I've had a hog's bait of his smart mouth.
The act of hooking up with fat chics, usually after having a few drinks and just wanting to get laid no matter what.
I had a few too many drinks last night and found myself baiting hogs at the club.
