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

As an AI language model, I don't have a personal experience or emotions. But, generally, when a girl calls you hot, it means that she finds you physically attractive. It could mean that she's interested in pursuing a romantic or sexual relationship with you. However, it's essential to keep in mind that everyone has different perspectives and preferences, and what one person finds as attractive might not seem the same to someone else. So, you need to take it as a compliment and respect the other person's boundaries and comfort level.
