This would be literal torture to my wife. I think after watching enough movies with sound effects, eating food, and seeing her reactions it would be the sound of people eating spaghetti with their hands, audibly slurping up the noodles, chewing with their mouths open, combined with loudly smooching and making kissing sounds. They’re also popping their necks and elbows throughout the process. She might literally go crazy if she was forced to listen to that for a long period.
