there a couple of ways to DHV, the one thats most common is with telling stories to the girl and include details about how your ex gf was a stripper, a model, or actress. your job is high status and you are in a leadership position. you stand up and protect the women you date. thats all basic stuff, this can be done but i have found it is the least effective way to DHV. most guys screw this up and it sounds like bragging.
i found a better way is to have your wingman do an accomplishment intro on you. in other words he tells the story for you, then you come in and join the party. anytime a chick you want to game hears a DHV from someone else, its much better. 3rd party DHV, doesnt have to be from your wingman, could be one of her friends, or whoever. think about how many people that have hooked up say, we met through mutual friends. thats where it comes from.
the best form of a DHV is if she observes you portraying high value characteristics. this is where body language is very important. good appearance yes, not overly important, but helpful. she sees you being the center of your social circle, laughing, having a good time, being the leader, the alpha dog. she sees you talking to other hot girls and gaming them successfully. she sees that other hot women enjoy your company. she sees other hot women touch you and can see that they also are interested in sex with you. that gives her some competition. you must act as if you are the alpha male in the room, and that every chick is already attracted to you. you must act as if having 10 hot women around you is normal and happens all the time. if brad pitt walked into a bar, how would he act? thats high value, thats how you act. its easier said then done, but a little bit of practice, and you will see massive results.
