A dumb move often performed by people too bored with a first-person shooter wherein a player using a sniper rifle fires and kills a target, without zooming in, while turning around as fast as humanly possible.
i totally owned that noob with a 360 no-scope. oh wait, that wasn't ownage, that move is pure luck.
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!!!
