'Tidy up time', when used in reference to adults.
Let me explain. My PIL are amazing and they do a lot for us, but my FIL can be astoundingly patronising sometimes (imo).
We've had a lot of work going on in the past week, all the windows being replaced, garage roof replaced, house roof repairs. Apart from working mon-wed, my youngest has had a vomiting bug (started tues) and now his older brother has started an hour or so ago.
PIL called to see how things are (as they do and very nice of them it is too). FIL asks about the house and then asks if I have done "tidy up time" on the garage. I mean seriously. What planet is the guy on? I replied that no, I hadn't as I had been too busy trying to work whilst small children vomited all over me. Plus trying to keep them away from the builders as I can't take potentially contagious children out.
So, AIBU to have been mildly rude to my FIL (my delivery was a bit snappy) and to loathe a phrase which only has a place in nursery school?
