I feel kinda stupid admitting it, but I have this, like, BAD. I try to keep it under-wraps or hidden. If I have to sit and hear the same repetitive noise repeatedly, like loud chewing or snoring, I honestly begin to feel a little violent, as if I want to just hammer first the offenders' face into mush.

Of course I'd never act on those feelings, but those feelings of rage are real. If you want to piss me off, one of the very few ways to do so is to smack your mouth/lips while eating, snore loudly, slurp food, etc. Shit drives me insane.
