Below is a cool "direct approach" from a seasoned successful PUA. And he got her number.
Him: I spot a petite Mediterranean looking girl walking along. She has an awesome figure, and I'm having naughty thoughts. I catch up to her, stop her, and use the tried and tested opener 'Excuse me, I just noticed you walking past, and I thought you looked really nice'.
Her: *Silence. *Blank stare.
Him: Usually a woman will thank me for the compliment. This one seemed a bit overwhelmed. Yet, on a street stop, a man must be ready to fill a whole minute of silence if necessary. So, I persisted: 'I like how relaxed you looked. You were walking along like there isn't a care in the world.'
Her: *More silence*
Him: 'It's different, because normally people walk like they're on some kind of secret mission. Like there's some sort of big rush. But you were very chilled out. Like maybe you do yoga and meditation, or maybe you have figured out the key to eternal happiness, and you can...'
Her: 'I take zumba classes'
Him: Thank god, she had finally piped up. We had a decent chat, but she started to panic at the number close..
Her: I'm really busy...
Him: Aren't we all? This life stuff is hard work. Tell you what, give me your number, and I'll invite you out, and you can decide then.
So I got her number. Probably won't go anywhere, but it was just the first approach, and there are plenty more where she came from...
This is way too generic and scripted can practically guarantee this didn't go anywhere
The best and i mean the very best can improvise on the spot
I can do it but only when the girls on my level if she's not it will crash
One opener i use in the gym when a girl is on her phone is " hey that weight isn't going to lift itself"
but after all the nonsense women have seen and heard over the years from "pua's" I can't help but think the tried and tested "can i buy you a drink" is probably the most welcomed approach
From there you can gauge wether she is actually interested
