Acronym for "nothin' without your scope." Also known as ANWYS, or "ain't nothin' without your scope." This term is used in FPS games such as Halo when taking damage causes a player's sniper rifle to zoom out. The affected player generally has great difficulty returning fire, as they have to re-shoulder the weapon or suffer severely reduced accuracy.
NWYS: NOTHIN' WITHOUT YOUR SCOPE, NOOB.
