A Scheller is decribed as a "nut in a shell". Scheller is a human that speaks before they think. A beyond weirdo. Described in Germany as the "Heller Scheller" the weirdest of all German nature. They flip at the drop of beer glass then go and hide in their nut shell. Dare not to disturb them until they had their alone time cause that's when the heller comes out! Sheller is a human nut in a shell that even Hitler wouldn't yeller at a Scheller! I shit you not...

Hitler- Carry on Scheller so sorry to disturb your Shell time.
