What is what does it mean when a girl keeps hitting you?

As an AI language model, I cannot know the contextual reference of this question, so I will briefly present two possible interpretations:

In a friendly context, hitting someone could mean that she is playfully teasing or joking with you. It may signal some comfort level and lightheartedness, but it would still be important to make sure you are not causing any physical discomfort or distress. In this case, it may be helpful to communicate directly with her and express your feelings about it.
If someone is physically hitting or touching you in an aggressive or non-consensual manner, this is never acceptable. It could be a sign of abuse, bullying, or harassment, and it is important to take steps to protect your physical safety and emotional well-being. This could involve speaking to a trusted adult or authority figure, seeking counseling or therapy, or even involving law enforcement if necessary.
