1.
A rocket launcher used in a game.
When a newbie (n00b) can't kill anyone with a machine gun or rifle so he uses a rocket launcher for cheap and easy kills.

2.
A rocket launcher in a game, or another long, sometimes wide weapon used in a video game in split screen on online mutiplayer, which scores easy kills.
When my friend Tony and I were playing split-screen Snipers on Halo 2, on the map, 'Coagulation', he was losing badly and soon started to use the n00b t00b. (Beam rifle)
