Most of my OCDs, but some of them do help in real life such as "EVERYTHING MUST BE PERFECT!!!!!!!111"
Hipsters, Apple (I have to admit their products are well built and look good sometimes), most of my classmates (because all they think is that Beats by Dre. are best, so it sucks to get absorbed into the world of audiophilia sometimes), slow people (but I can't blame them because not everybody can think fast), unsanitary people (especially ones who don't wash their hands after they use the bathroom), people that try to talk to me (I'm very silent IRL), I could go on forever.
