With seemingly everybody using the same darn sound effects library, it can be hard to avoid certain things. Watch old Universal tv shows and movies, and the exact same loud shrill telephone sound effect pops up every time. (It was used even in the 90's.) I think even Ben Burtt once mentioned how much he hated it.

If you're listening to a specific song or bit of music when you get bad news, that can set up an unfortunate association in the mind that triggers an emotional response whenever you hear it again. I have one or two of those. :/

Everybody probably has a tune that's like nails on a chalkboard whenever you hear it, but why that is I have no idea. There was one summer where a Paul McCartney song was on the radio about 100 times a day, and I couldn't stand hearing it again for decades afterward. I'm cool with it now, but there are others in my personal audio torture chamber I can't write off to overexposure.

"Muuull of kintyyyyre!! Ooooh mist rolling innn from the sea... my desiiiire..."

Maybe slightly off-topic but if it's "wierd things that wreck movies for people?"

For me it would be characters we are supposed to like, ignoring waiters in restaurants. Kinda makes me instantly think they are actually rude pr*cks. Even in a scene like 'Jack Rabbit Slims' from 'Pulp Fiction' where the waiter isn't just an extra (He's played by Steve Buscemi), our two heroes just sit in uncomfortable silence while he serves them their drinks, no please, no thanks, no cheers, not even a smile or a nod... I'd have p*ssed in their 5 Dollar shake and Vanilla Coke! ;-)
