Doubtless, or the TV series where people put their pet hates into Room 101, presumably to vanish permanently.
Quite.
Being immersed in cold, dirty, water would be one of mine, though rats would be quite high on the list as well (I suspect that is true for most people).
Car drivers, in the UK mainly, who overtake me on my bike, I’m doing 20mph, and turn left in front of me. Several near misses.
So longs as I don’t have to go into the room too:
Switzerland and Luxembourg
The word “so” when it’s used to answer a question. “What do you do for a living” response: “So, I am a secretary” Absolute nonsense, how did it start?
So, it all began … 
And literally.
" I literally fell off the cliff". And yet curiously still alive.
And ‘like’ .
As in it’s like really bad, and he said like. Agghhh stop saying like.
Oh yes. my son uses ‘like’ in every other sentence, sometimes more than once. Also is glued to his smart phone all the time. Much as I love him and his annual visits, there is a tiny bit of relief after a week. 
I mean like it’s a proper word , but it’s like when its used inappropriately like, that it drives me mad.
Sorry.
My 2 neighbours who despite a hosepipe ban can be seen early morning or late evening watering their plants with a hosepipe while everyone else is using watering cans.
I searched on our water suppliers website and there is a form you can fill in to report them, and the punishment?
The person might be contacted and reminded of ways to save water, nothing more.
I cannot stand the trend to talk about historical events in the present tense.
The most guilty of this ridiculous & confusing habit are historians!
Did I miss a grammar memo late last century?
Well it’s proper like, innit. I mean, innit. Yuh know, like, what I mean?
Personally I prefer to hold conversations with people whose IQ is higher than their shoe size (rules out many politicians, unfortunately).
Yes no exactly, drives me mad.
You actually get an s on yes?
The only room 101 I knew of was the torture room from 1984. Many of the answers, and indeed the question itself, seemed truly bizarre until someone mentioned alternative rooms.
The Present Hysteric tense 
Boomers, eh?
Use of the word ‘so’ at the start of a sentence.
And, Eddy Mitchell,
Oh, and Dutch people.
I don’t mind Eddy Mitchell if you mean the singer.
So, no yes actually
