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!!
