Loud Chewers
One of the more lighthearted entries, loud chewers and mouth noises made several lists. It’s not just a pet peeve—some people say it triggers misophonia, a strong emotional reaction to sound. Slurping, smacking, and chomping in quiet rooms were common offenders. A few even joked about creating separate eating areas for “noisy diners.” While it’s probably not enforceable, the request was loud and clear.
