People who has lag in multyplayer games that can never be solved neither by changing ISP , Getting broadband nor by buying new computer or moving to a new place..
lolz0rs originates from the original phrase used by 9 year olds, lol, which means "Laugh out Loud" but this particular variant is used by geekdorks, startrek/scifi fans and the like..
An extended version of the extremely overused 'lol', of course meaning laughing out loud, or laugh out loud(but of course you know that if you know how to click internet explorer). It is used to signify that you are a chewb, but is intended from the user as a sarcastic way of insulting people that overuse 'lol'.
Maegan quit saying lolz0rsessess, it makes you sound like a completechewb.
