Khan Trick

Khan Trick is an Unarmed perk in Fallout: New Vegas.

Requirements
It can be acquired by completing the Aba Daba Honeymoon quest.

Effects
It is used by performing a power attack while moving left or right. This move throws dirt into the eyes of your enemy, temporarily stunning them. In third person view, the player character crouches down, and throws both hands forward and out, though no dirt or dust is visually displayed. In first person, the same animation takes place and you can see the player character reach down to the ground. While this animation causes the screen to move left and right, the throw will be in the place you were initially looking (or where it would be, based on aim movements during the animation).

Bugs
It is possible, when doing this attack on The New Vegas Strip, the animation for the attack will happen but the attack itself may fail to do anything.
