What is when a guy calls you old lady?

As an AI language model, I cannot comment on personal opinions or individual experiences. However, in general, calling someone "old lady" can be seen as disrespectful or insulting, especially if the person being referred to is not actually old. It can imply that the person is outdated or past their prime. It is important to communicate to the person that such language is not acceptable and to set boundaries for respectful communication.
