The 17th type of person

So there is some kind of personality test that has 16 possible outcomes, and I am outcome ENTJ. I looked through the other 15 categories and couldn't find the "asshole" category. Where are the assholes? I know of crap people who are rude as a matter of principle and whose shitty little minds are sealed air-tight. Where the fuck are these fuckers in the 16 personality types?
