[ Cats ] Open Question : What does my cat's body language apply?

He sat down next to me and batted at my leg lightly with his paw. When I looked down at him, he stared at me and kept doing so until I pet him. When I stopped petting, I continued doing what I was doing. Not even 3 minutes later he did it again. After this process, he sat up off his side and curled his tail on my forearm while cleaning himself. His tail had a nice grip for being a tail. Does this imply anything?
