A large group of barbaric people that normally reside on the west side of Evansville in IN. Their main food staple is pizza. They are of extremely German descent, and love saying things like "in with the good, out with the bad." And they are all catholic. The word "rodenberg" actually means to "uproot a mountain" in german.
