KSI

The biggest coon you will ever see. That guy that has the most annoying laugh but makes your life so much crazier. He is dumb and smart at the same time.

“Did you see that black guy I was just talking with? What a KSI...”

KSI

Online Gaming Community consisting of over 12,000 members, spanning across many different games, including, but not limited to: Halo 2, Halo 3, CoD4, Runescape, WoW, Battlefield: Bad Company, and many more. An age restriction of 17+ was installed in May of 2008 in order to weed out whiney and immature gamers, and to improve the community as a whole. KSI stands for Knowledge, Strength, Integrity. (see ksiglobal.com)

KSI is made up of 45 different divisions, with names such as Double Helix, Synthetic Reality, etc.

Gamers joining are required to change their icons and mottos to reflect their squad and division. Example, joining the squad Fatality in the Synthetic Reality Division would show up on your Motto as, "KSI Fatality SR."

Any who question the authenticity of KSI are encouraged to add KSI Kryox on Xbox Live.

Even though everyone who plays Halo says they hate KSI, they'd suck a dick or two to get in.
