A girl I've met a few times said this to me yesterday. We've hugged before so I just didn't get it. I've had this happen before with another and I just said "then you owe me one" and then I did hug her later. This time though I got angry and just left because I thought about it and I can't see any reason to say that to someone regardless of mood would say this to someone unless they just want them to leave. I felt that she wasn't worth my time if she was going to act like that. In hindsight, I think I could have also told her "if you ever do that again then we're not talking anymore" then just continue with conversation. Not hugging is seriously one of my boundaries
