Describes a mate or partner that has perfected his craft through years of seeming like a great catch when in all actuality...he suddenly, and stealthily reveals himself as a complete douche bag.
Great husband and family man...and poof, the douche ninja comes out of nowhere and reveals that he is a cheating, lying scumbag. You had no idea. Surprise attack. Many victims.

When two or more guys do douchy things to eachother over and over. Usually over something dumb that happened a long time ago.
GUY A loses a bet to GUY B and doesn't follow through with his end of the deal. GUY B proceeds to call him an asshole and takes a dump on GUY A's porch. GUY A retaliates by smashing GUY B's window.So on and so forth.
GUY C: "What's going on between them, I thought they were best friends?"
GUY D: "Oh they douch-it-out all the time. But I think it's gonna end soon cuz the big fight is tomorrow and they both got tickets to go.

Related to karma. People like to believe that when you do something kind and generous you will be rewarded. Similarly, if you've been a real douche (asshole) they believe that karma will cum and thrust his big black dick into your mouth. And CUM again. So what hapens when we get CUM all over our new sweaters without having done anything to deserve it? Thats when you get a douche credit. This means you've already been punished for your future wrongs, so basically a douche credit is a get out of jail free card which you show to karma when you do something bad.
Person A: Fuck dude, why did you just beat the shit out of that helpless grandma and break an egg on that jew's head?
Person B: I have douche credits and I'm gonna use them all! Biatch! Asshole!
(Person B gets hit by a car)
Person A: Fucking idiot.
Person B: I have douche credits and I'm gonna use them all! Biatch! Asshole!
(Person B gets hit by a car)
Person A: Fucking idiot.

The douchey styling of one's hair into a single poof or point at the front of the head. May be natural, though is often a result of unecessary amounts of hair gel.
Brandon: Jeff, what's with your hair?
Jeff: What? You don't like my douche poof?
Brandon: OH MY GOD YOU TOOL BAG.
Jeff: What? You don't like my douche poof?
Brandon: OH MY GOD YOU TOOL BAG.
