A person who has gained weight and does not look good after their weight gain.
That girl did not fat-well...I feel bad for her.

Get the Fat-well mug.
When a fat guy is well-fed. Or when someone is more than just well-fed, but fed on what makes him very fat.
-I feel like I've eaten half a cow. I'm well-fat right now.
-Not as well-fat as the other guy, though. He must be eating fast-food and red meat all the time.
