He Says, She Says: Flirting Moves That Work (and Ones That Never, Ever Will) - MSN Relationships - Slideshow
Erin says: The wink can be friendly or cutesy, but if you really want to stop him in his tracks, modify it. Try the slow wink. You close your eyelid and then open it slowly, and at the same time roll your shoulder forward and lift your chin, like you're laughing in slow-motion. But just know that this move is lethal, and it sends a message loud and clear. You might as well give him your room key. I've never used it on a stranger.
Ryan says: The wink is good in theory but difficult in practice. I'm not very good at winking, so I've never pulled this move — and if I saw a girl do it, I'd assume she had a twitch.
