Despite my nick, anger is one of the worst states for me to be in. My biggest problem isn't losing control when I am angry, but the fact that I am in total control of my anger yet choose to use it to hurt everyone that may have been involved or around. In my youth, this anger was used towared physical destruction of doors, walls, objects, other kids etc...
As I aged, I learned to use my very keen sense of peoples emotions to really get them where it hurt. When I am pissed, I become very task oriented on whatever I am doing while also extremely vulgar and spewing the most hurtful words you can imagine. You might think I am kidding, but I become really aware of what buttons to push in the meanest ways, and even able to penetrate the thick leathery hides of INTx's.
Obviously this is all done in the loudest and most evil way possible, and making everyone unsafe by just being around or saying calm down. If I spot you, expect to be hit (emotionally) where it hurts (in your most vulnerable area). The good news is that to get to this stage of anger, takes a good amount of pressure, so if it occurs, it was probably severely and unneededly and really harshly provoked. Most of the time I would just get loud when its simple things but kinda walk away till I calm, but if it gets to that stage, no I want to be there to see the words cut you.
I have no idea why this would happen, i.e. striking people on their vulnerabilities, because in normal times, I would never ever, ever, ever, try to hurt anyone and go great lengths to protect peoples weak spots from others by defending them and or changing topics or complementing them etc... to help them overcome their weak points, and see their better side. I think its the inate ability of the ENFP to spot the good in people and motivate them, that also gives us the shadow ability to spot the worst in people and point it out.
Anyway, I posted this without reading any of the other responses so I don't dilute my own thoughts on the matter, so I am curious to see how many people can relate to this or am I just an evil bastard.
PS: I rarely get that angry as stated above, and it never lasts for more than five minutes.
