Loaded dice are those that have been manipulated by putting weights in the die so they will land on a specific number. It is illegal to do this. Very clever crooks do this and if caught, they usually end up dead. Lumbered is a negative concept. It is usually mentioned with breathing. His breathing was lumbered meaning he Had trouble breathing. He was out of breath.

"loaded" dice have had weights added so they always land on certain numbers. Playing with loaded dice means cheating. "lumbered" is not a transitive verb, a word is missing after it. Lumbered around, lumbered into, etc. It means to walk heavily, destructively.
