Knife-Edge Chop
From Gomerpedia
A knife-edge chop is the most commonly taught form of bedside chops to medical students. In this physical maneuver, the examining medical provider uses a backhand swing to hit his or her patient in the chest, to which any crowd of onlookers will scream "Woo!!!" in salute of Ric Flair. A knife-edge chop is effective if the patient's chest is noted to turn a bright shade of red.
