Our instructor use to teach us that. It's the tornado kick...shit gets you dizzy though. Impossible to block since you're torquing your entire body, but he executed it perfectly by psyching him out with another kick that never came until it was too late. Love seeing these...another cool one is the Brazillian kick. Hard to get the timing down when you're defending against it.
I see Pettis and Makdessi pulling this off...
