Before I start, I would like to point out that their is quotation marks around the title, meaning I'm referencing a piece of literature or audio, not me bitching about preaiming, but about people (more specifically some of my friends) bitching about preaiming.
So... preaiming. This was something I've never heard of before, ever in any FPS game. Their's quick scoping, hard scoping, and no scoping but I never heard of the term "preaiming" ever until all of my PS3 friends got PS4s and continued on their Destiny journey. Keep in mind that these are the type of people that spread tilt, or otherwise negativity that affects their skill during the middle of a match. I'm usually the one that stays quiet unless something is extremely bullshit; even then, I keep my tilt inside instead of expressing it verbally because of the effects of tilt.
Yet when they get killed by snipers (they can also snipe) they blame it on them for "preaiming" like, wtf is preaiming?! Do you mean hard scoping? Do you expect them to quick scope you every time?! Do you not know to not cross sniping lanes?!?! DO YOU REALIZE YOU HAVE A PRIMARY!!! MIDA! UNIVERSAL REMOTE!! SLEEPER SIMULANT?!?!?!
