Many of these phrases are absolutely fine, and I don't find them annoying at all. However, I do find them very annoying when used incorrectly, which is what a lot of management seem to do.

I have a nasty habit of correcting or asking questions about meaningless phrases:

2. Touch base

Thank you, but I don't want to play for the company rounders or baseball team.

3. At the end of the day

It's dark and I'm either asleep or in a pub. Oh, the end of the working day? Ok, I'm going home.

6. Blue sky thinking

Yes, nitrogen scatters blue light, what's that got to do with my job?

7. Out of the box

You want me to unpack the new shiny toys? Cool, lead me to them. Where's the screwdriver?

10. Singing from the same hymn sheet

Is it not rather bad form to bring religious doctrine into a place of work in a mostly secular country?

13. Ducks in a row

Repeats of Terry and June can be found on cable TV. Fortunately, watching them is not in my contract.

14. Brainstorming

I am not troubled by epilepsy at the moment, and my job doesn't require me to know much about it. Why are you talking about it?

16. 360° thinking

Gets you back where you started from. If you're going to just go in circles, can I go home?

18. Pushing the envelope

Bring me the head of Willy the mail boy! He knows he's not supposed to fold, spindle or mutilate!

19. At this moment in time

Do you mean "Now"?

20. In the loop

I don't have one for this, but loop reminds me of rope, which usually means sailors, so I can use the pirate icon. Yarr!
