A device or weapon in a FPS (First Person Shooter) that is far superior to the other weapons in the game. These devices or weapons can be spotted by their wide use and incredible stopping power. Newb-sticks are generally used by Newbs, amatuer players with little or no skill, or players that just plain out bad at the game.
"Dude! No fucking way! That Newb-stick got me again!"
"Dude wtf ? I shot him twice with my bolt action rifle, fucking newb-stick machine-gunner."
"What a pansy, only rifle he can use is one with a potato at the end of it, what a newb-stick(er)."
