Sad to see it, but "youthful exuberance" usually relates to children, doing things really silly to call attention to themselves, and when those "children" are older than their teens, becomes pathetic.
Even sadder, when such nonsense is allowed to dominate adult behavior, under some guise of
'Entertainment" at professional levels to lower standards or respect for both the competition, as well as the opponent.
Somehow, when such behavior is frowned on, and/or immediately subject to consequences and penalty those (actual children), at the NFHS level, are usually able to successfully cope with their personal disappointment and control their individual emotional reactions and need for gratification.
