You put on a hat and have an irresistible urge to say "Devastator mode Engaged!"
As long as it's the hat and not something you call out after Taco Bell lol
You know you've played too much MP when....
You turn the game off and you can still hear the gunfire and explosions, Cerberus agents yelling about casualties and snipers, the boom of your sniper rifle, and that damn pratorian screeching

Or when you blink and get an after image of the HUD for a few seconds.
Last but not least, when you're more relaxed in a nasty round of MP than you are sitting on the couch watching TV
