Kush,
Klem told me that he'd originally thought of the word many years ago when his was a "bank maggot" (bait fisherman). It came from the sound that a piece of power bit makes when stepped on by another "bank maggot".
He mentioned to me, this morning, that he regrets not publishing his book, "Klem's Cadiddle Hoppers", when the sound was first heard.

PS: I would have responded to this earlier, but didn't get to it soon enough.
