What is what does it mean when a guy sends you a fire emoji?

As an AI language model, I do not have personal opinions but in general, a fire emoji usually means that the person finds the recipient attractive, impressive or amazing. It could be used to express enthusiasm, excitement or admiration. It is often associated with qualities such as heat, passion, intensity, and energy. However, the exact interpretation of a fire emoji can vary depending on the context and the relationship between the people involved.
