YY about most of these, especially anything previous comments about hands (small, long nails, bitten stumps of nails, hygiene, etc.)
Tight trousers or jeans, especially if they are ankle grazers, and worse still with no socks and pointy shoes. And they are usually in loud packs 😬
Certain laughs, particularly the aggressive cackles from the aforementioned pack - one is annoying but particularly unpleasant in unison
Too much saliva - when eating, talking, randomly picking teeth with their tongues if food is stuck - gross (although TBF this can apply to anyone)
Low foreheads
Baseball caps on anyone over a single digit age, especially when worn back to front
"Roadman" anything, bad enough on young men but older men like this - just no
Unwarranted comments, from "cheer up, it might never happen" to nastier ones just because you didn't give them the attention they so desperately crave
In my younger days I split from a lovely guy because his voice irritated me, nothing else 😑
TBH, quite a few. If I weren't with my OH I'd be gladly permanently single!
