look up any word, like blumpkin:
noun - The transition in which a "n00b," or a beginner, becomes "l33t" in a certain area or field, espically in internet gaming (e.g. counterstrike).
1.After playing CS for about a year, Joey went through nooberty and was so l33t he was able to join a Cal-O clan.

2. I hope I hit nooberty quick so I can scrim my friends.
