When asked to give an example of "shalele", the kind sir had a perplexed look on his face, as if he had just been asked to solve a quadratic equation or discover the origins of goat cheese. Then he exclaimed, "Hand me that shalele over there and we'll figure it out, mate!"

I may be wrong on the spelling, but a shalele is a Gaelic noun used to describe a club, larger than both a blackjack and night stick, and heavier.
