KSI

The ultimate clan for douche bags on Halo 2 or Halo3. They feel the need to act superior to everyone they know (including Jesus) and make you change your whole profile to fit theirs. They also have an extremely faggish ranking system that only makes sense if you are mentally retarded. They really aren't good at halo, but make themselves look good by adding many people. They just plain suck. Even the Teletubbie clan is better than KSI.

~Pre-game lobby~

KSIxXd0uch3Xx: Hey you want to join KSI?

JohnnyAppleseed: No, I heard you are a bunch of 43-year old pedophiles who want to melest teenagers.

KSIxXd0uch3Xx: Uhh... Ummm... that's not true.

JohnnyAppleseed: Well that clan sucks anyways. I would rather join the Teletubbie or Hello Kitty clan. Both of of those clans could kick your ass.

KSIxXd0uch3Xx: Come on man, I'll suck your dick if you join...

JohnnyAppleseed: No, I'll pass. I don't want to be in a clan full of gay cock suckers.
