What is what does it mean when a girl calls you handsome?

When a girl calls you handsome, it generally means that she finds you physically attractive. Being called handsome is often considered a compliment, and it can indicate that the girl is interested in you romantically. However, it is important to remember that everyone has different tastes and preferences when it comes to physical appearance, and being called handsome by one person does not necessarily mean that everyone will feel the same way. It is always a good idea to take a compliment graciously, but not to read too much into it.
