lulzorzasaurus! 

The act of continuously "Laughing Out Loud" until you're head explodes, thus forcing you to watch rather long marathons of "The Hills" on Foxtel all day long. And as a result, change your name to Chelsea and sell fairy floss.

TIM: LULZORZASAURUS!
JAMES: *shocked face* Oh no you didn't!!

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.
