I think this is my least favorite expression in conversational speech. I find that it becomes an answer, even though it doesn’t convey any meaningful content. It is often used in argumentative speech, e.g.:
ME: Why did you call me “behemoth pork muncher?”
YOU: I didn’t mean it in a bad way.
ME: Yes you did, you’re calling me fat.
YOU: No, I’m just sayin’.
This really has not resolved anything in the argument; yet, it serves as a conversation stopper. I hate it. I’m just sayin’.
