I found this video, it's a good intro to watch. English dialogue, subtitles in French.
Pay attention at about 1:20. Notice how one minute he's cute talking to the cat, then he's talking casually, defining what "speed seduction" is, then his vocal tone changes. His eyes lock onto the guy he's talking to. Listen to his voice, he goes "radio announcer", slows down and says "it's a deeper, much more imaginative" and there's a very subtle emphasis on "deeper", a slightly longer pause following that word. At that point the interviewer sees what he's doing and calls him out. But it's a tiny taste of what he does.
He also discusses his trigger phrases like "can't help yourself" - this is evoking an emotion, which he describes, then talks some about weasel words (new direction vs nude erection). RJ is daygaming. He talks about the advantages. He talks about the same stuff as Roosh with respect to selecting a seat in a coffee shop, then sits down and cold reads his way into a conversation with a blonde MILF. Look very closely at what he does there. This is stuff you don't get from a book, you have to hear it and see it to get it. Look at what happens when the announcer tries it - he just doesn't sound right. He finally gets latched on to the idea, and you can hear the change in vocal tone - he's very relaxed, calm. That last girl he gets a number from he fucked up - he approached from behind, sets off her creep alarm, and then suggests they go somewhere and look at the stars - she's probably thinking "serial killer!" but she gives up the number anyway.
Yeah, I know, it could all be faked. Anything could be faked except your personal experience.
RJ is gaming older women in this, and my general feeling is that this works a bit better on older women. But I don't have much experience with it, maybe some of the guys have good experience using this on younger girls.
