Jeez man.
Neg isn't an insult. It's a statement that SHOWS the girl that she's not on a pedestal.
When a girl enters a room and all the guys start staring and approaching her, they have her on the pedestal. She feels it, she's bored by it. She doesn't want anything from these guys, and a person who doesn't want anything is impossible to seduce.
Then comes a guy who doesn't put her on the pedestal. Once she's talking to him, she feels it. She feels a bit challenged and wants to test her sexiness. Her ego is demanding that SHE can make YOU supplicate and like her. It becomes her goal.
From that moment on - she wants something from you. And you're gonna toy with her like with a kitten - jerking around her object of desire, letting her take a close look at it, almost feel it in her arms, then removing it.
Is it easy to pull off? Not very. Does it work? yes.
