Takes very little skill to use and can kill whole groups of enemies with a single indirect hit, yet the explosion needs to be fairly close.
To be used liberally against elitist gamers who play games all day because they can't get jobs and whenever they can't win they start crying. Much amusement to be had reading their abuse.

"Dude, this kid with the noob tube killed me like 6 times already, its really pissin' me off!"
Surprisingly, despite its name, it's not primarily used by noobs, or newcomers to the game. It's actually used more by assholes that are well into the game already but only use it to piss off their opposing team. And unfortunately, they usually do succeed in pissing off their enemy which could (and normally does) result in the enemy team changing their class to a noob tubing class while saying something like "Oh you wanna noob tube bitch? I can do it too", and that results in an entire game session being nothing but noob tubes and/or RPG's, depending on who's in the game.
Highly disliked by the majority of the gaming community. Avoid noob tubing at all costs to ensure that you don't start a tubing chain-reaction.
