Jung said in Ptypes/chapter X that Introverted feeling is especially negative feeling. The ones I know are pretty hateful. Jealous to the max, over-suspicious/paranoid about their partner cheating. Always taking revenge on their ex-es, breaking up in a way to maximize damage to the other. Talking about them to others as if they are bastards/retards/pieces-of-shit/scum-of-the-earth (but they actually picked them themselves??). Also they use a lot of vile language. And they dont care if they look slutty/dirty/cheap/sleezy/lowclass. Ready to take themselves down in a fight or drama, ready to stamp their body full of ideologies they dont understand (tattoos) just to annoy the crap out of all others. The only way they learn is when their enemy's enemy presents them something, because the enemy of your enemy is your friend, something like this. This is also how these girls work when there is trouble with their boyfriend, they fuck another (his competitor/enemy) the next day. This is also how they flock to opppositional groups, like join "tattoo people", join "the escort agency". its not for love of the tattoo or the escort business, its simply because of hate for something else. (because dad or boyfriend pissed them off or whatever)
