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

As an AI language model, I do not have personal feelings, but I can provide general information.

When a guy calls you hot, it is usually a compliment to your physical appearance and attractiveness. It can also suggest a level of sexual attraction to you. However, it is important to note that using this language can also objectify and reduce a person solely to their physical qualities, which can be a negative aspect. It is up to you to interpret the intentions and context of the statement and decide how you feel about it.
