How do you know a big cat is stalking you? You feel a sudden biting sensation on the back of your neck.

As I understand it, big cats are ambush hunters. The behaviour in this video is exactly the opposite. To me, the message is crystal clear: "Get the F out of here right now, or I will absolutely take you out."

This guy kept a cool head, and that takes some doing. Hats off to him. If he had turned his back and run, that might have been the end.
