I like panniculus because it's medical and sounds science-y. "You're super morbidly obese and have a grade 3 panniculus" sounds like you're sizing up a strange specimen. Whereas "you're an eatbeast with a massive gunt" sounds like you're insulting someone. Both have their ups and downs, but I like making them feel non-human more than I like making them feel attacked. They walk around with a victim complex like they are always being attacked anyways.
