GeneralFap,
It's a very nuanced issue and my article only covers the generals. But seeing as you're just starting out, you need to do what I did: bite the bullet and just do it. Don't think about it. Just like your first few daygame approaches. Just gotta move your feet.
If you disagree with someone, call them out. In front of everyone.
Add in curse words, adopt arrogant facial features (Damon Salvatore is a great role model), and learn how to give intense eye contact.
Laugh when someone says something stupid, as if you were watching a funny movie and are chuckling to yourself.
Now remember, don't do it ALL THE TIME. Do it when there's a REASON. If a girl is being sassy or rude, just flick her off and smile. If a girl is talking too much, put your hand on her mouth and say "stop talking." I don't think I ever remember a girl slapping away my hand. They either just still themselves and laugh like they just got put in timeout, or they start licking my hand (which means they wanna fuck).
Basically, if you have the DESIRE to be rude or arrogant, do it. But when that desire isn't there, it's probably not appropriate and will just make you look stupid (trust me, been there tons of times).
Once the desire is there, ignore all resistance your mind puts up. These people would fuck you over sideways if it would profit them, and that's the honest truth. Most people you think are your friends should really be considered acquaintances. Not sure the average quality of the people you chill with, but if most of their conversations are about getting fucked up, talking shit on each other (mostly behind each other's backs), and idle gossip about inane bullshit, they're not good quality people - they don't have higher level values and that means they'll submit to lower level values, which includes throwing people under the bus if any serious profit could be reaped from it. I just had my teeth cleaned and my dental assistant told me about how she was working with some engineers on a concept for cars and she casually told her friend about it. A few months later she heard from a friend of a friend that this person she told was traveling all around the world. When she asked why, this other person told her that she'd sold a concept to GM for millions of dollars. This was nearly a decade ago and that "friend" has yet to return a phone call or made any attempt to communicate to her. Straight up thievery.
Shit, my goddamned little brother in my fraternity went behind my back to hookup with my ex, even though he knew feelings were still a bit sore. Now that I know the signs, he had sociopathic tendencies, but man, was that a shitty lesson.
I love people and think that this universe is perfect in every way, but I never forget that everyone is ultimately in it for themselves. Not only is this the truth, but it's a necessary truth. People HAVE to be in it for themselves. It couldn't be any other way. It's not bad or good, just is.
You'll see, homie.
