A wide full fisted punch not nearly a hook, more like using your arm as a rope with a brick on the end. Usually implemented by drunken aboriginals as a form of assault against train station security and old women sleeping in their beds.
Completely ineffective in a real fight, and when successful has little effect on the receiver.
