The only thing I have close to a phobia is my dislike of close up eating. Not like sitting across from someone enjoying a meal, but like sloppy eating that approaches the absurd. Mukbangs (they're literally nightmare fuel for me) come to mind. I've also experienced something like this on a smaller scale firsthand. I can't think of many movies by title that capture this phobia, but one that comes to mind is Society (1989). The "orgy" has a certain "absurd feast" element to it that completely fucks with my mind.

Texas Chainsaw 2 has some of that in it, and the ending of Fresh (2022) with that small clip of Sinister overlords practically naked sitting around a feast table. There's a lot of films out there that displays that sort of thing. I usually to avoid them, but good horror is good horror.
