Are you sure?
It is from here:

and if you really want to, you can scroll over the below (it is even more un-nice than the INTJ one):
Scumbag- ENFP
I have a feeling you're not going to like this much. Do I care? No. How do I know? It's because you hate criticism. You love to be loved and you'll do anything to be accepted.
Unfortunately for you, I can see right through your insincere compliments and over-the-top greetings. No matter what you do, I'll always hate you for what you are. An arrogant, unstable, overly enthusiastic scumbag.
I bet you're pretty proud of your accomplishments, huh? You seem to achieve at whatever you put your little mind too. Trust me. Nobody likes the person who is good at everything. NOBODY LIKES YOU.
This might also have something to do with the fact that you're a cheating machine. You're just not the type of person to make long-term commitments. You enjoy seeing "what could be", rather than being satisfied with "what is." This, of course, means you often leave others in the dust while you seek out another lover.
Well, at least you're not the one left in the dust.
Unfortunately, when you're the one lying in the gutter with a bloody knife in your back, you might think differently.
A lot of the other descriptions are pretty funny though =P
(Edit: the above post beat me to it....)
This one was harsh and spot on for my type:
Freak-INFJ
Well, well, well. How did someone like you end up with the least common personality type of them all? In a group of 100 Americans, only 0.5 others would be just like you. You really are one of a kind... In fact, I do believe that that's one of the definitions for the word "FREAK."
Freak's not such a bad word to describe you actually.
You are deep, complex, secretive and extremely difficult to understand. If that doesn't scream "Freak!" I don't know what does. No-one actually knows the REAL you, do they?
You probably have deep interests in creative expression as well as issues of spirituality and human development.
You've probably even been called a "psychic" before, because of your uncanny knack to understand and "read" people without quite knowing how you do it. Don't fret. You're not actually psychic. That would make you special and you'll never accomplish that.
You're also quite possible the most emotional of them all, so don't take this all too hard. Nevertheless you most definitely have the strangest personality type and that's not necessarily a good thing.
P.S. I didn't really agree with the ENFP one when I read it.
