What is Xwn?
To extremely own somebody in a online game. Some times used as ixwn because when you own you cant just own, you have to xwn them. Like when your in WoW when you see an elf who looks really gay and you need to use your axe to split his head open. You are in the xwn.
I just xwned everybody in Unreal Tournament 3, now I am god like.
