'south-brawn' means, 'shut-up, Rhun!'
For decades I didn't understand what the bandit leader meant when he yelled at one of his followers, "south brawn!"
Then I purchased a dvd copy of KRULL. Thanks to the miracles of modern technology, I turned on the English captions and discovered what the bandit leader was saying. He was yelling, "Shut up, Rhun!"
How in the world could he pronounce, 'shut up', as, 'south brawn' (phonetically)?
