When the only way you are turned on is if your girlfriend wears a ghillie suit.

When you actually hold your breath when sniping.

You yell, “Let’s do this” before anything you do.

You see a spider scurry across the room, step on it, and yell “plus ten!”.

You yell “Cover me, I’m Reloading!” when you put more paper in the copying machine at work.

Your dog joyfully jumps on to you and you break its neck.

You hold your breath to steady your pencil while writing.

When you start naming the different guns in war movies.

Your playing soccer and when the game starts you sprint to the nearest corner flag, lay down and shout Securing Charlie!

Later in the game when the opposition has a corner kick shout We're losing Charlie! Then run over and punch the player taking the corner.

You're in the boss's office, steal his briefcase, open it for 5 seconds, close it, trow it out of the window and say bomb defused, Good job team!

When you envision spraying your teacher with a silenced P90.

When you are all alone and you hear in your head: "Get it done Marine; you're all that's left!"

When you get shot in a game of paintball but think you can continue playing because you 'equipped Juggernaut'.
