An overloaded moke (who appears to be smarter than his owner)."Moke" is indeed a disparaging term used by Hawaiians, meaning somebody big and dumb. However, as near as I can tell its usage preceeds that by many centuries in English-speaking countries. It is an archaic British, Australian, and United States slang term meaning donkey. I cannot tell you where I first heard it, but it was long ago in my youth, which was divided between Michigan and Ohio, far away from Hawaii. There are no racial overtones, intended or unintended, to the term as I understand it.
