I'm an anti-zeitgeist by virtue, so I hate everything that becomes popular.
High School Musical, Harry Potter, Twilight, Hanson, N-Sync, Hannah Montana, the Jonas Brothers, Avatar: The Last Airbender, and recently, Naruto.
I never saw any of them(with the exception of Naruto), but I know that I hate them. Some people call it having taste, but I know its just me being difficult and anti-social.
EDIT: I learned through conversating on Skype that 4 phrases will get you through almost any boring conversation:
1) I see.
2) Indeed.
3) Heh.
4) Good luck with that.
and a fifth for Ruroken fans that I use frequently: Oro?
