‘It is what it is’ seems to be the latest no-meaning utterance to be added to all the others.
If a speaker on the radio begins a sentence with ‘So …’ I turn it off — which means I don’t listen to the radio much.
The gestural equivalent to a no-meaning statement is the ‘weather presenter’s gesture’, which involves beginning with the hands together in front of the body, and then opening them both out, while keeping the elbows in, and then returning the hands to the centre – before doing it again a moment later. It has never meant anything – and yet it is done by everyone on TV. It seemed to me that weather presenters started it, but it’s not important, as it’s done by everyone now. The business news guys are strong supporters of this meaningless gesture.
