as pertaining to fisherman:
the first examples of the term being used to describe other fisherman was in the early 1930's in the diary's of pissed off fisherman.
def. - A potlicker in fishing is a
man who is too
lazy to
go find fish on his own, so he looks for someone who is already on fish and then he moves into that
man's spot. He potlicks, he's a lazy bastard who depends on what others find or leave him.
We had just started putting some fish in the
boat when some damn potlicker sees us catching fish. So he drives up and anchors just 20 yards off our
bow and begins to cast towards the
spot we found.
