look up any word:
1. no scope
The act of not scoping to kill an opponent.
Commonly used in Halo with a sniper but not limited to.

No scoping is NOT applicable to weapons where scoping is not required. ex. ak47, m4a1, battle rifle, SMG, etc.
Blue guy 1: No scope headshot!
Blue guy 2: Nice!
Dead guy: I just got owned..
2. no scope
The act of shooting someone with out using a scope or cross hare, usually only meaning something if it's a headshot. Therefore, there is no such thing as "no scoping" in Halo.
"Yo, I just no scoped someone with the AWP."
3. no scope
Generally speaking, the act of killing someone in a first person shooter game with a one shot gun (sniper rifle, bolt action rifle, etc) without using a telescopic sight or sniper scope. Most commonly, the term is used to mean that you fired such a gun from the hip and killed someone with it, however it can also (debatably) mean that you pulled up iron sights on a sniper rifle / bolt action rifle and then killed someone that way. The term does not apply to shotguns, semi-automatic rifles (unless they can be scoped), or any automatic weapon.

No scoping is generally viewed as an act of skill (or luck, depending on who you talk to and the mechanics of the game you're playing). This is because you are killing someone with one shot through a (usually) large crosshair and also risk exposing yourself if you miss. However, the amount of prestige that is attached to a single no scope depends on the distance and rate of success; i.e. if you no scope once and do this by killing a guy who you are literally next to, that doesn't take much skill, but if you continually no scope guys who are halfway across the map, that's some seriously good shit on your behalf. On a related note, no scope headshots get you some serious prestige if you can pull them off constantly.
Example (in COD5):

Player 1: Damn, I just no scoped some guy on
4. 360 no-scope
Usually done in FPS but taking it to real life is better. EX: playing a sport like volleyball. Toss the ball up, do a 360 while your eyes are closed, and try to hit it.

Do this to any sport from 360 throwing, to 360 kicking.

People love you for it.
DJ not nice: Yo! you see that awesome 360 no-scope serve?

Kim Jung II: Yea bro that was sick as hell!!!

"Jimmy why didn't you do your home work?" his teacher asks.
"I got the gamer-aids that'll make you scream!, i've tried wall banging, i've tried no-scoping, nothing works." jimmy cried.
"there's no cure at the moment :'(" jimmy said, a single tear drop rolling down his face.
6. TM Scope
A form of lesser no-scope where the scope button is slightly depressed before the shot is fired causing the targeting rectecule to shrink without the scope actually reaching the eye. This technique has the advantage of increasing the accuracy of a no-scope without it being defined as a hard-scope, however its use is prohibited in many major no-scoping clans as it allows for the no-scope to be performed without the necessary skill required, thereby making the technique accessible to just about any noob on the net.

This scope was originally developed by the reputable no-scope specialist- Ch40TiC DaMaGe- during a no-scoping private match (NSPM) on Terminal during the sixth age of CoD (2009-10) and has remained in common use to the present day- however many modern historians have disputes on the origins of this technique as many claim it was introduced by Ch40TiC DaMaGe's rival Scooter4Ever.

Since its founding, many people have tried and failed to replicate the true skill and dexterity required to perform it.
No way man, you can barely TM Scope!!!
