A stroke played by swinging the bat in an "uppercut" fashion so that it catches the ball partly from below; in the follow-through the bat flails up and round vertically, through an angle that may exceed 180 degrees. The shot was so named in a Pepsi soft drinks commercial featuring Indian batsman Mahendra Singh Dhoni, who frequently uses the shot. The helicopter shot is very risky, but can be unusually effective at scoring boundaries against yorkers.
