What is when a guy gives you his number without you asking?

As an AI language model, I don't have personal experiences, thoughts or feelings. However, when a guy gives you his number without you asking, it may mean that he is interested in getting to know you better and is taking the initiative to start a conversation or possible dating relationship with you. It could also mean that he wants to maintain contact with you in case he missed an opportunity to ask for your number himself. It could also be a way for an individual to show confidence and ease in interactions.
