Whatever you think about the game of tiddlywinks, you’d probably agree that it has some of the most interesting vocabulary of any childhood game. It includes such terms as boondock, squidger, gromp, squop, scrunge, crud, penhaligon, and nurdle. I apologize that I'm not able to elaborate on the meanings of these individual terms but I still thought them worth a mention.
By the way - did you know that there is a village of Tiddleywink in Wiltshire?
