An expressive hand gesture in which the individual thrusts their hand forward in a fist in front of them; traditionally extended from the chest parallel to the ground outward. At this point the individual expands the fingers, and then retracts their hand while oscillating their fingers individually upward and downward. This motion is typically used to indicate the individuals proposed ease of completion through which an action was purportedly difficult to achieve.
