DON'T DO THAT!
Yeah, don’t do that. Meeting women really isn’t that hard. Be direct. Don’t be clever. Don’t be cute. Don’t be indirect. And above all, don’t be weird.
My advice: lock eyes, lift your head a little in a reverse-nod, and say “hey”. If she smiles, lifts her eyebrows, or says something like “hey yourself’ in a coquettish voice, then ask her name and go in for the kill. If she doesn’t respond in a positive manner, or if she rolls her eyes or says something like “what” then just nod and move on without saying anything at all. After all, you’re a man who knows what’s up and when it isn’t up.
Remember, a woman decides in less than three seconds what category you are in for her. So don’t bother wasting any more time on an initial approach than that, and definitely don’t spend that three seconds signaling to her that you are an insecure low-status gentleman who is definitely going to call her “milady” at some point.
Here’s the thing. If, upon further observation of you, she becomes convinced that she initially put you in the wrong box, she will always come find you and let you know that she has changed her mind. Which, after all, is the female prerogative. For those of you who are a little slow with regards to these matters, that’s what’s happening when a girl who initially blew you off subsequently comes and initiates a conversation with you for no reason.
It’s worth noting that a focus on approaching women is a strong indicator of low status, for the obvious reason that if you’re a high-status man, you know that women approach you at least one-third of the time, and probably even more for a man who enjoys a higher status than me. In that case, your main job is to simply be encouraging when she’s working up the courage to come talk to you by smiling at her or otherwise acknowledging her presence.
