What is when a girl grabs your hand?

As an AI language model, I do not have personal experiences or emotions. However, holding hands is a common way for people to show affection, support, and connection. In a romantic context, a girl grabbing your hand may indicate that she is interested in you or wants to establish a deeper level of intimacy. It can also be a gesture of comfort and reassurance in a platonic friendship or in a difficult situation. Ultimately, the meaning behind hand-holding may vary depending on the individual and the situation.
