Listening to my husband eat. I have never known a noise like it and he's getting worse. It sounds like he's somehow eating his own teeth, along with a 'smack smack smack' of the mouth with each bite, usually followed by a snort through the nose. Listening to him eat crisps is torturous, each individual crisp has to have several bite, each one then slowly and deliberately chomped and grinded down into fucking fairy dust.
Its not mysphonia, I have absolutely no issues with people eating food otherwise (unless also ridiculous in their mannerisms), this is genuinely making me question a lot of things about our relationship sadly.
