I Can't Stop Watching Luis Suárez Waving His Hand Like A Weirdo

Seriously, who does it like this?

Is he miming to someone how to screw in a big-ass light bulb? Is he trying to create the illusion that he can spin his wrist 360 degrees? Is the person he’s waving to on top of a building next to the stadium looking at him through binoculars, and he’s wagging his hand and grinning so demonstratively to make sure they can see him?

His waves usually aren’t this bad, but are still pretty bad:

I know it must feel counter-intuitive, but in waving there’s no penalty for getting your arm in on the action.
