Thank you Dick and Big Unc and Yorkshire Pudding! Dick you did not muddle it at all. Skittles is the word not used here. Yes Yorkshire I know bowling. It is probably close to what we call a pin split except thereis only 2 pins. (Skittles) and with that I understand the phrase. Thanks for your help!
It is all intriguing in many ways. Ten pin bowling is nothing like bowling. Bowling is a game where the aim is to get a bowl as close to a target as possible - even touching. It is not a game where things are knocked down. You cannot knock down a ball, (like the jack) or another ball. Knocking things down, particularly pins or skittles is skittles.
