Another name for a grenade launcher. Called a 'noob tube' because in video games it takes a little or no skill to get kills with and the grenade launcher is shaped as a tube. People get pissed off everytime they get killed with it.
Player 1: *takes noob tube out*
*fires at player 2*
Player 2: *turns off his computer*
