Lots of names are used interchangeably because they are generic in nature. If you need to dig a hole in the dirt and send someone to get you a shovel, everyone pretty much understands you are not wanting an aluminum grain scoop.
"Idiot Stick" is a term that my Dad used to cover a whole range of shovels. Once I had to bury a cable across my gravel driveway. I asked my elderly neighbor if he had a pick ax I could borrow? He did, and he told me to keep it, saying he knew where it was should he ever need it, but otherwise every time he looked at it, it only made him think of hard work.
