Get the Duty Rider mug.
One who plays nothing but Call of Duty and can not accept the fact that Battlefield is way better just because the ride it's dick and just buy it because it's title say CALL OF DUTY and because a new one is made every year.
Friend: Yea, so you gonna get that mw3.
Me: Nope, that's a waste of money, bf3 is badass.
Friend: Battlefield sucks. everyone's turning in their copy for mw3.
Me: It's because you and everyone else are "Call of Duty Dick Riders".
