Where or what is the rule restricting what you can ask?

Alright, well, I can't ask Yahoo about this and I can't find it in the FAQs, so I guess I'll ask it here. I know that you cannot post anything ually explicit, illicit and whatnot, but how or could I ask about a movie that I've seen which would fall under the a category? There would be nothing explicit in the question, even though I would be describing a scene which is semi . I am trying to locate a film which I can't remember the name of. I'm pretty sure nobody would know what it was anyway. Is the rules such that you can't ask anything remotely related to adult or films, books, so on?
