That's Mystery from Neil Struass's The Game. It read like fiction until his celeb characters arrive, then I googled Mystery and his forum Mystery's Lounge, and realized these were real people and Strauss really did share these experiences with them. The Game starts with Strauss learning the pick-up techniques but evolves into the back story behind the guys in the pick-up scene (yes, there was a scene- complete with other teachers running $6k seminars!) and how it was anything but seductive. Picture describing XPT to someone and trying to explain that it's actually not about porn. Honestly, The Game one of my favorite books. I always pictured Mystery more Marilyn Manson than 1997 Canadian raver douche, though.
