Definition of Granade Luncher in Call of Duty 4 Modern Warfare. It is preety much the same as in Halo or CS but it is really annoying as it one-hit kill even if the user shot it on the ground nearby or bounce it from ground (it will pierce you then...). Especially annoying on noob public Search and Destroy servers played on small maps with fixed spawn points which often means BOOM => GG... The only good thing is that it is banned nearly everywhere and has only 2 bullets... Often called Noob Tube or Noob Stick as well.
Fagot with noob stick: ZOMFG! I PWNED U WITH MAH PR0ZORD NOOB LUNCHER!
Punk Buster: Player (Fagot with noob stick) kicked for using restricted weapon: Granade Luncher Result: Permanent Ban.
Yet Another Normal Player: *Sigh...*
