The peashooter effect
The phenomenon that happens in FPS games where you'll be killing enemies, but then when you get to one of the enemies your gun starts feeling like your shooting peas while your enemies gun does enough damage to kill you in what looks like 2-3 shots.
Yo I was grinding my 3 kills without dying camos last night and when I got to my 3rd kill my gun felt like a peashooter while my enemies gun hit like a .50 cal. I think they call it the peashooter effect.
