I'm pretty sure iron age people knew the concept of spoiled food and would be able to apply that to stories. You people know it has nothing to do with car spoilers, right?
How a word is used can induce confusion too. It'd be like if someone said "Anyway, Rotteners for the comment. Sorry."
Though 'rotteners' would be a good word for a spoiler that makes you hate something afterwards haha.
