That stereotype applies to the guy in his 50s who's maybe 20lbs overweight because he's a functioning alcoholic, hence why he's always "jolly" aka buzzed. Deep down the "jolly" fat guy is more likely than not miserable, spiteful, and bitter about something in his life/past which he drinks to get away from, but it's more likely to be a genuine source of angst than made up tumblrina bullshit. There are obvious similarities between him and the common Ham, but I think there are enough differences that it might warrant a subspecies.
