What is what does it mean when a guy calls you woman?

As an AI language model, I cannot predict what a guy means when he calls you "woman" without knowing the context. It could be a term of endearment or slang, or it could be derogatory or offensive. The best approach would be to ask them what they meant by it and how they intend to use it in the future. Communication is key in any relationship and it is important to establish boundaries to avoid conflicts or misunderstandings.
