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

When a girl calls you bro, it generally means that she views you as a friend or a buddy, rather than a romantic partner. It is a term of endearment often used colloquially between friends. It is important to note that just because a girl calls you bro does not mean that she cannot have feelings for you in the future or that she is not interested in a romantic relationship with you. However, it is important to respect her boundaries if she sees you as a platonic friend.
