What does it mean when a guy wraps his arm around your shoulders?

This guy I talk to a few times a week was with my friends and I. When it was time to leave, we all stood up to go inside. My friends were left behind, so it was just me and this guy. He wrapped his arm around my shoulders, pulled me toward him, and said, "Come here." After that, he was like, "Come be my new best friend." A few seconds later, he said, "Has anybody ever told you you have a nice ass?" When I didn't respond, he took his arm away and moved me away from him by slightly pushing the back of my neck. What is this supposed to mean? I'm so confused about him doing the last part.
