Shiola...
I read a comment today that reminded me of working for a South African guy who used the phrase "He doesn't know shit from shiola" That's not how I first heard it and I'm sure something got lost in the miles from America to South Africa. He probably heard it from a few distant relatives.Let's go back a hundred years or so where George Melancthon Wetmore invented boot polish in the form of paste that sold in round tin cans under the name of Shinola.
In America, it was pretty commonplace to describe someone of lesser intellect who doesn't know 'shit from Shinola'
The Southern version is not knowing the difference between 'shit and apple butter' where they add the explanation 'he had to smell it to see with one to eat'
Yesterday, a young associate of mine said "Catch you on the flip-flop" and I asked if she knew what that meant. Her response was no and I explained it referenced CB radio jargon where truckers who frequented the same roadway would greet other truckers coming and going. One heading east and the other heading west might pass each other on the return trip back home.
