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. It is
literally a club intended to f$%K somebody up, plain and simple, trespassers, or anybody
bothering you. Just like a ballbat, a shalele is heavy enough to do serious damage, but lighter than a ballbat.
