When I watched it the first time, I was thinking he was just scratching his face. He had done so with his little finger earlier.
But then I watched this from a different camera angle, noting the reaction of the crowd — and HIS reaction to their reaction, and was convinced.

I did notice the crowd laughed/cheered after the hand movement, because during the hand movement he was not talking. And if they’d been cheering what he said just before, they’d have been cheering while he was making the hand movement.
If you watch the audience you will see his supporters “getting” exactly what he is doing when they see the signal then start talking about it and start hooting and hollering.
