I have only seen the first video clip, but she is a bit weird. For any type.
I would agree she in not an enfp. She uses her eyes in an interesting way- lots of side to side extreme glances and extremely direct stares. I have most often seen this pattern in EXTPs. (An enfp will almost always break at various points, when discussing emotion and look downwards at an angle- a kinesthetic pattern in NLP which may be representative of introverted feeling. The extreme side to side glimpes in NLP are auditory-perhaps hinting at Fe). However she seems very into a lot of things like odd fashion, and the wierd comment about liking linguistics, was very much an INFJ sort of interest. She doesnt seem socially smooth enough to be an EXTP to be honest. I have only known two INTP females, thus am lacking data, but they were both quite reserved and took the distance this person has to a much greater extreme and seemed much more reserved.
So I'd say INFJ, although I have never met one quite like her before.
EDIT-Oh, no offense intended if my decsription seems at all harsh, as i realize some of you guys are fans.
