>>105392403At the core these are two different kinks with significant symbolic overlap.
In one camp you have - Gays who like Chubby Bara boys. The type of character you'll see lusted after here are pretty antithetical to traditional beauty standards. Often masculine or "ugly". Wide frames (from muscle and bone structures not just fat), flat noses, hairy, often shorter than average or much taller than average. Nelson and Soos are a good example.
The second camp - Gays who like weight gain. The characters you'll often see be popular subjects for weight gain are usually pretty attractive in traditional sense. Generally 'normal sized' to implications of slightly pudgy. Attractive faces and good hair. But the personality is usually a key factor in making the viewer want to see them get fatter. Dipper and Bart are a good example.
Technically there is the third camp, females who like dad bods and Di Caprio tums AKA Peter Porker
>>105332535 / females who like fucking huge men who are fat but also very strong AKA RubyZlitchDragon Heart Boxcar is the best example I can come up with at the moment, pic related.
