I've been trying to type my friends boyfriend and it's been particularly confusing. He scored ENTJ on an online test 
Everything I know about him:
- Math major - he was really good at it, found it easy overall and really liked it
- Listens to some seriously violent metal bands, is really good at crossword puzzles
- Has a strong aversion to office work, he doesn't want to get a "real" job right now because he doesn't want to cut off his dreads and have to wear dress clothing. Apparantly he doesn't want to give up his individuality, and absolutely hates anything formal or professional
- Hates losing at something and not being right (or in control?).. I beat him in a battleship game and he was sulking all day
- Is extremely frugal
- Smokes a ton of weed pretty much all the time
- Has strong opinions about everything
- Seems to like people but does not care much about how he comes off to them
- Seems almost suspicious of everything, is really negative
- He's pretty witty and and catches everything that is being said
My guess would be INTJ as it seems like he uses too much Fi for an ENTJ.
