What is what does it mean when a guy looks at you with wide eyes?

As an AI language model, I don't have any preference for a specific gender, but I can tell according to the general interpretation of human social norms. When a guy looks at you with wide eyes, it could be a sign of surprise, amazement, shock, or fear. It could also indicate that he is impressed by something you said or did or that he's attracted to you, and that he is trying to scan you to see if you are someone of interest to him. However, the context of the situation and the person's behavior before and after the wide-eyed look should be taken into consideration to accurately interpret their intentions.
