obergruppenführer
An obergruppenführer was like the worst boss ever in the Nazi SS. They were the kind of leader who made everyone want to quit and probably wished they were dead.
My boss is an obergruppenführer. He yells at me for breathing wrong.
The obergruppenführer at the factory made me work 20 hours a day and called me a 'useless subordinate'.
My history teacher said the obergruppenführer was the reason the whole world was messed up.
