IB

The International Baccalaureate is the international qualification that likes to take you're pure and innocent little brain and butt fuck it raw, without the curtesy of using Vaseline. It tricks you into some sort of false security of being inside of an elite club due to the "prestige" of the course, only to find out it is where the rejects with no sense of social compass like to dwell.

Gaza: Yo Stevo! Who are those weirdos over there? I've never seen them before.
Steve: Jesus Gaza! Stay away. They're the IB freaks.
