Does negging work on Tinder? Do you use it as an opener or midway through the conversation?
Negging is an extinct term. It turned into some sort of low grade insults meant to undermine the self confidence of a woman so she might be more vulnerable to your advances. If that's the intent most women with larger that a peanut sized brain will spot it a mile away and ghost you.
Ok, I see. So I take it that 'The Game' is démodé by now. What is a more updated PUA book?
Not so much PUA books but the following should help with just about any human interaction:
1. How to Friends and Influence People
3. The definitive book on body language (I believe that is the title)
IMO books that are designed to make to you a more charismatic, sociable, and influential are more rewarding than many of the dime a dozen PUA books. Philosophical and religious text are also a great boon if you read them approach them with the proper mental attitude.
