I consider someone fluent in their 2nd language when they can speak it fast and quick and understand about 98% of what people say, I think that would be considered 'fluent'. Just put it this way, when you can pop out a foriegn language joke, speak their slang, their dialect, enough to ask and respond to any answers in or out of the house in public or in private, that's being fluent.
