PUA is a stupid term. But if you're into that stuff, look into Real Social Dynamics. Tyler and Julien have come such a long way and have broken more into personal and professional development which is more universally applicable.
To sum up their mantra now, it's all about breaking out of the echo chamber of your mind, being mindful but also congruent with reality (be empathetic for instance, but don't be a weirdass loser), be able to offer value and be free from outcome (go out to have fun, not to smash pussy). The old "PUA" stuff was all about negging girls, teasing them and trying to bring them down. But that's not sustainable, nor is it ethical, and relies on tricks and gimmicks to smash drunk chicks... it's not hard to do that. But work on yourself, become magnetic and able to socially calibrate yourself to any scenario and you'll build better connections. Period.
RSDTyler and Julienhimself are their usernames on Youtube. Anyone can create a good couple hours of laughter and sweep a drunk chick off her feet and back to their pad. It just takes a few weekends of practice. But you should focus on offering value and not being some slick piece of shit PUA phaggot.
