Let's first break it down.
Call Of Duty:a popular video game
Call Of Duty (aka: Cod) is a game that, when played too much, can cause this syndrome. It's easy to spot someone with Call Of Duty Syndrome. And gamer who constantly gets frustrated at a video game because of, lag, an over powered weapon, poor game mechanics, yet never their own fault that they are doing poorly in the game. They also blame modding, and hacking and even if they like the hand they will say it's a terrible game because their doing poor. They also blame their team, however a bad team is a common frustration in gamers with and without cod syndrome.

Call Of Duty causes this because it often has lag, over powered weapons, and poor mechanics etc. so players tend to blame these things and use it as an excuse for doing poorly in any game.

People with Call Of Duty Syndrome often think they are good at every game because trick shotting, an unfortunate fate of cod, raises gamer ego even though it's purely luck getting a 360 ladder jump silent shot YY or some bullshit. Excuse my language, though if your looking this up your probably used to this language.
Gamer 1 (with symdrome): wow what an asshole using an overpowered weapon man I swear this game sucks!
Gamer 2 (without syndrome): You've played too much cod lately, you've got Call Of Duty Syndrome, you should stop playing it for a while.

The Call of Duty syndrome is a serious disease caused by the Call of Duty series(A game series developed by some homophobic homosexuals somewhere). It's a state of delusionary paranoid outbursts. The species CoDtard are most vulnerable to the disease.
A few good examples of events that can trigger an outburst:
-An airplane flying by
-A person sprinting towards the person with the syndrome
-Meeting a Russian
-Meeting a German
-Hearing a loud noise
These events can lead to extremely violent behavior from the person with the Call of Duty Syndrome.
