It's like when perusing a book of item nomenclature at a museum job I had a number of years ago. I came across the existence of an object called a "barking spud," and while I know it is from the logging industry and therefore probably has to do with removing bark from logs, I'd rather not know for sure.

That was the same job that had an abridged dictionary which, at times, was less than useless, albeit highly entertaining. I'd kill time by opening it to random pages and reading definitions, and will never forget the entirety of the definition for "spanker boom," which was "A boom for the spanker."
