Neg Theory and Routines
Negs are intended to be false-disqualifiers and are intended to lower the target's comparative value to the seducer. Specifically, they are not insults - instead they resemble the comments of a person who does not view the target as being sexually interesting.
However, you should use negs with 9s and preferably 10s only. Don't use a neg on a 7 or 8. The 7s and 8s know what they are - cute, sweet, pretty etc - but not drop-dead beautiful. Their confidence in their own beauty is only fairly high and it could easily be destroyed by a neg.
And the neg hit might backfire with a 9 or even a 10, if you use it when she's really down - in a self-defeating, self-conscious, I'm probably just a 7 or a even 6 mood. Be sensitive to her mood and if, for whatever reason, she seems to be really suffering, forget the neg.
Here are a few examples:
◊ YOU: "I don't think we should get to know each other."
HER: "Why not?"
YOU: "I think you are just too much of a nice girl for me."
◊ HER: "Oh, I'm a model."
YOU: "What, like a hand model or something?"
