A word used to describe someone who is too big of a n00b to even deserve being called a n00b. The technicaldefinition of a Noobage, however, is what you get when you cross a n00b with a cabbage.
Guy 1: "That guy is completely pathetic. I'd bet he lives in his mom's basement."
Guy 2: "Yeah, bro. He's such a noobage!"
Deprived from the word ownage and pwnage, noobage describes a person who tries to win at everything, but fails. (What less would you expect from a noob?)
