Do you guys do this? If so, What lines do you use

Lots of PUA theory advises to open, and then straight away 'neg' her and also disqualify (yourself and her)

So it'd be like 'hi', and then 'your hair looks fake. Is it?' (neg). She in now intrigued about. And then 'Me and you wouldn't get along. You're too short for me (disqualify her). And then maybe something about how you can only be 'friends' or maybe that you'll be her 'wingman' for the night (disqualifying yourself)

That all works amazing in theory and in books, but anything close to the above example (which is taken from books) seems to do more harm than good in my experience lol. She is instead kinda hostile at the neg and will just grab her friends arm as if she wants to get away. She doesn't care about your 'disqualifiers' if you'r not her type since she's not interested. It doesn't make her want you as per PUA wisdom. Or it might even just make you sound a bit weird lol

I'm curious if anyone actually applies this stuff, and if so how. And when? (i.e - do you use it later in the set instead of how it is supposed to be used~?)
