It was not long ago that I too searched the internet for a perfect pickup line. In this desperate search for the cure to my mediocre approaches I came across a video that gave me some very key advice on opening.
The advice was somewhat like this: "Quite being a bitch and talk to the girl."
So I did and I was astounded by the results, the girls where receptive to literally anything I said when I was opening.

Here is how I did it.

1. I got in a good mood and was self amused aka I didn't give a fuck I just had fun no matter what happened
My mood leaked onto the girls who seemed to have a positive experience as well

2.I spoke with authority
Really important, if you speak like a little bitch you sound like a little bitch. If you speak like a badass you sound like one.

3. I didn't slur my words
If you slur your word you will come off as nervous and nervous a tell tale sign of a beta male.

4. Lead
You can say anything that doesn't require her response
Hey I'm [name]. then proceed to grab and shake her hand this is basic kino. After grabbing her hand you can proceed to lead her somewhere as you talk. NOTE IT IS IMPORTANT TO LEAD NOT ONLY CONVERSATION BUT LITERALLY LEAD
However you don't always have to take her somewhere right away just make sure that when you do move, you are leading her.

Hope this helped, I know that none of this is new, just thought it would be helpful to put it into one topic.

Please add anything that you can think of
