I slight upgrade from l33t. Which means to be "elite." The "zor" adds power to it, therefore making it describe someone who is quite extraordinarily elite compared to the average elite individual. Commonly used by nerds and almost solely spelled this way, by nerds.
"W00t! I am so l33tz0r! I totally roXX0red J00! Fear me! By the way, I've never touched a real live girl except for my mom! Although she is quite reluctant about that! W00t!"
