Left 4 Dead Syndrome
Left 4 Dead Syndrome (or Left 4 Deads / L4DS) is a common occurrence caused by extensive amounts of Valve's video game L4D (or it's sequel L4D2). It causes the victim to be constantly paranoid, often hearing noises such as various special infected or the Tank! music whilst outside of the game. Extreme cases may also cause the victim to down entire bottles of pain medication or yell out their actions such as "RELOADING!"
