sweepsniping 

verb - Sweepsniping (also known as sweepscoping) is a term made popular in the Halo video game series (namely Halo 2) which describes the act of scoping in with the sniper rifle and (with your sensitivity set to high) flicking the right analog stick while pulling the trigger. Due to the game's hit detection, if your reticle is anywhere near an opponent's head when you fire, the shot will be an insta-kill.

- "How are you so good at sniping?"
- "Sweepsniping, bro."
