description, explanation, When someone or something gets hit in the head or other part of the body in an extremely violent fashion it resembles the head shot J.F.K. took when he was assasinated. It would also most of the time but not always catch the person or thing totally by surprise. way way worse then a donkey punch. a shockingly large noticeable scar, mark, or injury, where a person seeing it could not ignore it,and might comment or ask questions about it.
