If your wife mistakenly refers to you as a "girl" while conversing, is that a good thing or bad thing?

While agreeing with my wife while she was venting, she said, "gurrrrrl, I know right". "I mean honey, you agree with me". Then after the conversation she said thanks for listening to me, I really needed that. She has done this on rare occasions before. Its always when I feel like she needs a friend to listen as oppose to her man. But I do get a weird bad funny feeling, like maybe she should be telling this to a "girl" friend. Anyone ever do or experience this?
