I've got a good insulting word substitute: "Gahenna" in place of hell or hades. Gahenna is from a Hebrew name for a junk pile-garbage and trash dump in ancient Israel just outside Jerusalem. Used by the ancient prophets as a visual description for bad people after their death-a place of great punishment and torment. Most people don't know this. Just say, "Go to Gahenna", and you will have other wondering what you are saying.
