lolz0r 

Like many other "0r" words (like bitchz0r, or hax0r, or sux0rz), this has an unknown origin. But it can be traced back to "lolsaur".

If you are a true lamer, use it. If not, AVOID IT AT ANY COST, or people will start to think you're a moron.

Person1: something REALLY funny
Person2: OMG lolz0rrrr!!!!111
Person1: yaaaaaa bitchz0r die cuz i am teh hax0rz

Person1: kekeke
Person2: kekeke! lolz0r!!!11

L0LZ0RZATTACKZ! 

When something is so funny it's both a laugh out loud and a personal laugh attack. The definition of epic koolness. Use this word when feeling uber geeky, nerdy, or just plain kewlz.

Dave: Why was 6 afraid of seven, dude?
