Christmas Noob
A type of noob, invading online games in large groups, appearing at Christmas morning. They are typically kids who just received the game as a Christmas present, skipped singleplayer/campaign, and went straight to multiplayer. Generally unskilled, prone to camping and getting shot, making them delicious targets in FPS.

Easily recognized, as most servers will fill up with players with the lowest rank / level.
Christmas noobs = fresh meat.
