Guy winked at me. Meaning?

Ok so theres this guy in my homeroom and 2 other cles and we do talk to each other sometimes but were not bosom buddies or anything. I think he's cute and I was talking to him about twilight. He said he was going to see it and I didnt believe him cause he's a jock but also super smart like me and I asked him who the main characters were to test him. He said Isabella, Edward, and Jacob and then he winked at me. He's the quiet but fun type. Can someone please interpret this for me?
