Unlearn all that shit you just mentioned. I'm familiar with all of that, it's all bullshit.
If you want to pick her up:
1. Smirk/slight smile+seductive eye contact. Move your head close to the side of hers and ask like a creep, "What's your name." She tells you her name.
2. The moment she tells you her name, say "My name is.." and put your hand out for her to grab.
3. When she grabs it, keep holding it, don't pull away first. Switch the handshake into locking hands and start caressing it. Tell her, "You just looked interesting so I wanted to get to know you

"
4. Give a small compliment like, "You have soft hands..."
5. Ask her for her number and shut the fuck up after. Let the awkward silence fall in.
6. She may ask "Why?" Just say, "I just want to do some innocent things with you." Use a devilish grin here.
7. If she says, "But I don't know you that much." Just say something like, "I got into a lot of trouble as a kid, I like watching good movies, I like pretty girls, I like hennessy, and I like you. You gonna give me your number or not?" Either that or just smile and don't say anything.
