Flicker Jab

A flicker jab is a form of off-hand punch that is delivered with very little power, but is difficult to predict. Usually used by boxers, the left arm (if the boxer is right handed) is whipped out with little or no telegraph, and "flicked" against the target. The flicker jab isn't meant to inflict serious damage, but it is hard to protect against and it allows the boxer to gauge distance and poke the opponent with relative impunity.
