Self-explanatory. What type, generally, is the least pretentious? By pretentious, I mean "trying too hard" to do something; putting "sophisticated" books in your facebook "favorite books" section that you haven't read, having lectures on your iphone that you only listen to when other people are around, etc. Pretentiousness is not just intellectual; a person like Dr. Dre is pretentious in relation to Eazy E because Dr. Dre went to an expensive private school but raps about being a gangster whilst Eazy E "keeps it real".
I've written about this before but I still can't clearly define what I'm talking about. I have a really visceral negative reaction to "pretentiousness" (In quotes because it's the closest word to describe it) and it's a quality I can detect within 10 seconds of meeting someone or reading a paragraph of their text on forums. Another way to supplement this description would be a lack of self-awareness; being totally oblivious to how they are being perceived.
