Crackie for me, when I was a boy or for anyone around the bay, a crackie was a nondescript dog that was no good. In Hare Bay where I live, people had dogs for hauling wood, and a crackie was no good for that; just a damn crackie. The other definition that I recall my dad would say; there’s uncle Bob coming up the road and young Jack is chasing him – that’s his son. He’s a real crackie – he’s always chasing his father. Somebody faithful.
