Incredibly annoying sounds/sights/whatever in proximity to you. Here're mine:
* Crunching chips. Not everybody's, not all crunchy items: Just somebody close to me who will go nameless. I actually have to leave. It's more like the style of crunching from this person, a big zesty *crunch* at the beginning followed by a seemingly interminable crunch crunch crunch.
* Slurping. Same person.
* Answering unintelligibly with food in the mouth. Same person.
* Scenes in movies of somebody embracing a toilet to throw up in. For some reason, screenwriters find this to be incredibly appealing, since they put it into so many movies.
* PDA(s) anywhere, by anyone.
* Sound tracks of movie sex scenes. Hmmm, is there a pattern developing here?!1 EDITing to add: If it don't involve me, I don't wanna hear or see it.

my long lost twin sibling?
I have the same food issues. Unnamed person who lives in my house.
Uses utensils like garden tools. Not so annoying if it's a spoon, but when it's a fork it makes a nails-on-blackboard scraping sound that makes me want to commit murder.
Slurping not a major issue, but shoveling is. As in, "who needs to actually TASTE their food? Just wolf it down. Not attractive.
The butterscotch candy adventures. This person loves individually wrapped hard butterscotch candies. No letting them dissolve in the mouth in a genteel fashion. Nooooooo!!!! Crunch. Crunch. Crunch. Crunch. Seriously, how many freaking crunches can one stinking little piece of candy have in it???
And, like you, PDAs. By anyone. I mean, what's up with that shit? Get a damned motel room, OK???
Conflicting soundwaves. Like when unnamed person has TV and radio on at the same time. Can't deal with it.
Flashing lights. There are two big screen TV screens visible from my recliner in the living room plus two smaller flat screens connected to surveillance cameras. Unnamed person in my home isn't bothered by the random flashing back and forth, off and on, security cameras switching scenes every few seconds. They're sort of like strobe lights. They drive me nuts. I have to shut two of them off, and after the unnamed person I live with goes to bed I turn everything off. No lights. No sound. ahhhhhh.... 
Fucking wheels rolling on some fucking stupid ass bus ALL FUCKING DAY LONG!
YES INDEED. 
"Rachel" too, except her name wasn't Rachel.
anyway, after I left the company one of the girls told me they had to hire three people to do my job.
So, needless to say, while I was actually there doing it, I was very stressed out and needed help.
So my supervisor hired a girl to help.
It soon became apparent that my Rachel was going to be more of a hindrance than anything when I delegated some work to her and she told me she didn't know how to file alphabetically.
WTF?
Anything I gave her to do, she didn't know how to do. And she would seek me out so I could help her do the work she was supposed to be helping ME out with. There was no place I could hide...not even in the company's very stinky and offensive smoking room (this was mid 1980s).
All these years later, I can still see her face in my mind...
aughhhhhhh!!!!!!!!!!!! 
Sounds like you'll fit in here just fine! 
If I want to watch a video, I will click on it myself, thankyouverymuch!
Maybe that's what's wrong with me. 
In winter? Backup alarms on snow removal equipment.
Since we have 2 seasons here, Construction and Winter, I'm screwed.
Oh, all condos are not made with 100% soundproof walls ?
the sound of the blender as mr. froggy made his frozen fruit slushes, but it stopped when I told him Skittles had offered his/her services. 
PTSD makes all loud noises and banging sounds a bad juju thing for me. I can't stand when those thumping stereos are within a mile of me, makes me suddenly change character like some kind of Mr. Hyde.
Being stuck in a small area with people who wreak of mint, I'm allergic to it.
Patchouli and anything made by AVON.
PDAs
The sound TeeVees make and people who are annoyed when I don't know what TEEVee show they are talking about because I don't do TeeVee.
People who are willfully ignorant of common sense activities like not walking up to a large wild animal to get the "nose hair shot" and get pissed when you try to tell them, for their own safety, that they should keep their distance (at which point I think to myself that a Darwin Award might be issued momentarily and I'm not sure I care to be a witness).
Chain saws and snowmobiles and those glass-pack exhaust kits on already loud vehicles.
Other things get on my nerves too but those are top of the list.
