This post not about sport; but, I would say, an early-twentieth-century convention too. It sometimes went to over-the-top lengths – as in “wagger-pagger-bagger” (waste-paper basket); and the Pragger-Wagger (Prince of Wales).
Actually the Sheffield Rules existed previous to the formation of the FA and always banned hacking and tripping and most handling, although smacking and punching the ball was still alllowed, and the Sheffield rules outlawing most forms of handling led to the creation of the goal-keeper and the header. So those weren’t exactly FA innovations.
