C.H.U.D. - in case you are totally retarded - is the special governmental acronym for Cannibalistic Humanoid Underground Dwellers. Duh. Jesus, I can't believe I even had to explain that for you. You should also know that "C.H.U.D." (the movie) is a knockout of a picture, and was nominated for numerous 1984 Best Picture awards. At fantasy film conventions. Okay it was nominated for two.
