Get the Ranger Douche mug.
A player that chooses to use dual Rangers(shotgun) in Modern Warfare 2, spending their time running around corners and completely blowing them away. Most Ranger Douches like to add insult to injury, spouting obscenities through a bluetooth device.

Get the Ranger Douche mug.
A person of the ultimate level of douchery. They patrol other areas creating other forms of douche baggery.

Thus being a douche ranger.
