What is when a guy acts weird around you?

As an AI language model, I don't have personal feelings or experiences, but I can provide general information on the topic. When a guy acts weird around you, it could mean several things. Here are some possible explanations:

1. He likes you - Sometimes, a guy may act weird around a girl he likes. He may get nervous or seem awkward around you because he likes you and doesn't know how to express his feelings.

2. He's not interested - On the flip side, if a guy is not interested in you, he may still act weird around you. He may try to avoid talking to you or may act distant or cold.

3. He's uncomfortable - Sometimes, a guy may act weird around you because he's uncomfortable in certain situations, such as if you are talking about something that he's not familiar with or if you are in a group of people he doesn't know well.

4. He's trying to impress you - Another reason a guy may act weird around you is that he's trying to impress you. He may try too hard to be funny or may show off his knowledge or skills to try to impress you.

5. He's just being himself - Finally, sometimes a guy may act weird around you simply because that's the way he is. He may be naturally quirky or have a unique personality that comes across as weird or different.
