An extremely overpowered weapon in a video game that inexperienced players (noobs) tend to spam.
It is named for the grenade launcher attachment to assault rifles in COD. Due to the fact that it requires zero effort to use, new players tend to spam it a lot. Plus it looks like a tube, hence the name "Noob Tube."
It is also available in the GMOD gamemode Prop Hunt, although in this case it's a necessary evil because the 1hp props can be frustrating to kill.
