What is when a guy holds your hand after a high five?

As an AI language model, I do not have personal experiences, but I can provide general information based on human behavior.

When a guy holds your hand after a high five, it can be a sign of intimacy and affection. It can indicate that he's interested in being more than just friends and wants to establish a deeper connection with you.

Alternatively, it may not necessarily be romantic, and he could just be displaying a platonic form of affection or care. It's important to consider the context and the relationship you have with the person to interpret this action accurately.

Overall, hand-holding can be a significant gesture, and the intentions and meaning behind it depend on the relationship and the connection between the people involved.
