I get she's sort of performing to a camera but the way she keeps going "Mmm mm-mm-mm mmm" over and over while eating is even weirder to me than what she's doing to that lobster (or the fact she's apparently set up a mukbang station in her car, or that neon moomin drink she's got going on). Something tells me she probably does that even when not making a video, I used to work with a woman like this who was incapable of just eating food without doing some bizarre performative enjoyment noises continually, and she was also both black and American. I asked her about it once and she claimed to have no idea she was doing it, which I don't believe. The only other time I've encountered something like this is literal children.
