Is there anyone out there who isn’t familiar with the high five celebratory gesture made by two people, each raising one hand to slap the raised hand of the other? Its dates back to 1944 when in the movie, Cover Girl (1944), Phil Silvers’ character, Genius, tears up a telegram and attempts to "high five" co-star, Gene Kelly. The “high five” is conventionally meant to communicate mutual satisfaction to spectators or to extend congratulations from one person to another.
