Her saying "indenjhin" instead of "indentation" bothered me more than the cottage cheese monster living under her bellybutton. I would never be so mean to someone IRL, but the door is kinda opened to criticism when you start making a bajillion TikToks.
I think it could be just, well, unfortunate, but I also wonder if maybe the distinct line is the result of surgery. Like a C-section or especially some sort of lipo or tummy tuck. I've seen sometimes weird things happen if someone has fat spot-reduced, then goes and gains a lot of weight. Forget which lolcow it was, there was someone that got their doublechin removed, then got fatter, leading to them having this weird little round baby roll around their chinline in a way you'd never see otherwise.
