Irritating words or phrases

Here's a thread that hasn't been done in a while...

Are there any turns of phrase people use that really irritate you for whatever reason?

For me, referring to anything as "so-called" usually makes me stop reading or listening to an argument, because 99% of the time what they're referring to is actually the thing they're claiming to be so-called. Around these parts and in internet comment sections it's usually something like "so-called politicians" or "so-called Irish Water" - they ARE politicians and it IS Irish Water, why put the so-called in there? I automatically assume anyone doing this is an idiot.

Another one is "X at its finest", which is so overused these days and almost always wrongly written as "at it's finest". Pedantic I know, but it's annoying.

Also any corporate speak obviously, flying kites and running things up flagpoles and all that ****e.
