"Hey, I don't think we've met. I'm [insert your name]."
Does that sound too simple and easy to actually work? The truth is, opening lines work better when they are simple. The more clever your opening line is, the more attention you draw to the line itself instead of drawing attention to YOU.
So go ahead and try this one the next time you go to any kind of social gathering. I use this line every time I go out, and I've met hundreds of women with it. I know you can do the same.
