I saw the pick up line video and as someone who cares about you I'm gonna give you a thread of what actually works when hitting on women who don't know you.

1. You don't walk up to a stranger and ask a question, you're already telling her you're an entitled fuck who doesn't care for boundaries. If you want her attention don't get too close to her

2. People notice you more when you're not trying to get noticed, also they might think you're a human trafficker or a creep (which is probably the case if you're talking to strangers even though your mom taught you not to)

3. So to get the best and most satisfying result in this situation you have to put as much distance between you and that person, go home and sleep knowing you didn't make anyone feel unsafe or uncomfortable.
