When playing Call of Duty; Modern Warfare 2 and you're on a decent kill streak and another gamer, of a lower rank, launches a grenade (via noob tube) in your general direction, without any sort of aim or skill, and kills you by sheer luck.

37.
Noun.
Despite many saying that this is something specific to Call Of Duty 4 it is in fact a general term for any weapon that is cheap and/or over-powered in any video or computer game, usually a grenade launcher or RPG but also, especially with newer games, can be a shotgun (i.e. Call Of Duty, Half-Life 2, Rainbow 6) at least when up close. Use of it is commonly frowned upon unless used with some finesse or tactical forethought.
Ex.1
Tom: "Dude, I was playing Halo 3 the other day some dude unloaded on me with the Mini-Gun."
Harry: " The Mini-Gun is such a Noob Tube"

Ex.2
Dick: "Gosh that guy just shot me with a Noob Tube."
Tom: "What a Noobish thing to do!"
