Si0X 

; A human being named Greg Long that got so good at video games that he was called Si0X, becuase of the vast coolness of the word. He was the ruler and best clan leader of all time. He is still today and ifact, Si0X is pwning some n00b at this very moment.

Oh Shit Si0X is the room should we quit ?

Si0X can I join your clan ?

Drop your pants Si0X so I can suck you off.
