4.
A highly skilled and adaptive MW2 campaigner who sees the opportunity to utilise a weapon and blow up a shitload of whiny assed bitches.

Seasoned noob tubers live to hear how whiny and bitchy anyone who's been blown to bits gets and loves nothing more than to hear the words "He can only use a noob tube,cus he aint got no mad skillz like what I haz" (sic).
I'm gonna blow these whiny bitches to fuckin smithereens cus I love to hear them moan.

Then I'm gonna tube 'em again.

Then I'm gonna let em get a shot off,to let them think they have a chance before tubing the tard out of 'em.

I am the King of the fuckin Noob Tubers. (i.e. I tube noobs).

This refers to a derogatory word used for an online gamer in, xbox 360 and ps3, in two different games. The word noobtuber is often used while playing call of duty 4 live, when a player uses grenade launcher attachments on all of their weapons in order to get cheap kills. They usually cannot get kills any other way. It also refers to halo 3 or halo 2 live, when a player uses a rocket launcher and/or a missle pod, and repeatedly uses it as it keeps spawning.
call of duty 4 example:
Lvl 52 Prestige: That fcking noobtuber keeps hitting me with the m16 launcher when I'm sniping. Someone call a UAV already so I can kill that biatch!

halo 3 example:

Col. Grade 2: Stop spawning our rocket launcher at our base you freaking n0obtuber. This is why covies suck: noobtube central

these people usually play COD, and just use grenade launchers, this is most likely because they DO NOT possess any skill in aiming and shooting their gun.
