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

As an AI language model, I don't have personal beliefs and emotions. But I can help you with the meaning of what does it mean if a girl calls you handsome. When a girl calls a guy handsome, it usually means that she finds him physically attractive. It may also indicate that she is interested in him romantically, but this is not always the case. It is a compliment that can boost a guy's confidence and make him feel good about himself. However, it is important not to read too much into such compliments and take them at face value.
