Was I drunk at the time?

So, kokopelli_24 posted recently in her LJ about something annoys her when reading fic. (I won't repost what here as it was a locked entry.)

Anyway - I responded to her entry with this:

It's similar to my rant about someone groaning into the other person's mouth when they've only just started to kiss. I know that sometimes things can be really intense when you first start kissing so maybe some low moans, but I've been on the receiving end of someone who just started groaning and trust me - it's weird

This is a pet-hate of mine. You just start kissing someone and already there is huge amounts of groaning? It won't kick me out of a fic, but it does often make me pause. (It was this conversation with Liz in our hotel room at ConTxt that ended up with us both making moaning sounds and freaking out our neighbours...)

Anyway! I have a point and will come to it now - I know that different people have different things that annoy them in fic. Something that I don't mind will make another person so annoyed that they will stop reading.

So! What annoys other people? What is your fic-pet-hate. And I'm not talking bad!fic here - I'm talking about a perfectly good fic that will include this and suddenly you are irritated or kicked out of the moment.

Any pairing, anything. I'm curious.
