I used to be a fit and athletic dude. I unironically modelled. I was juicing, mind you, but I looked like Adonis.
Then some stuff happened and now I fetishize grotesqueness. I'm 450 lbs, rolls of flab, long greasy hair that I wash as infrequently as possible. I have several rashes, and had a fungal infection under my gut flap. I haven't shaved and my beard right now is full of crumbs. I haven't showered in a couple of days.
I enjoy it. Presumably, these people do too, because they find their minds warped, and to them ugly = beautiful.
