Fist pump

The fist pump is a celebratory gesture in which a fist is raised before the torso and subsequently drawn down and nearer to the body in a vigorous, swift motion. The fist pump is sometimes carried out in parts of the Western Hemisphere, Europe, and Japan (where it is known as guts pose) to denote enthusiasm, exuberance, or success and may be accompanied by a similarly energetic exclamation or vociferation. The gesture may be executed once or in a rapid series.
