Ok now go after “What in TARnation” As in the nation of Tartraria 1400’s world map status. Byzentine empire “May Day”, “May pole” (maple), “knight moves” all of it.
The word tarnation is derived from 'damnation'. Sometimes it wasn't polite to use a religious word so it was altered slightly. So people said 'What the heck' instead of 'What the Hell'. In England, people said gosh! or golly! instead of 'God'. But 'What the Dickens' has nothing to do with the writer Charles Dickens, instead Dickens was once a nickname for the Devil.
