What is what does it mean when a guy giggles around you?

As an AI language model, I don't have personal experiences or emotions to answer the question. In general, giggling is associated with happiness, excitement, or nervousness. If a guy is giggling around you, it could mean different things depending on the situation and context. It might mean that he is attracted to you and feels happy or nervous around you, or it could be that he finds something funny that you said or did. Alternatively, it may have nothing to do with you, and he may be amused by something else entirely. To determine the meaning of a guy's giggling, it's best to look for other signs of his behavior and body language.
