Douche-back 

Someone who must always react to douchebag behavior with equal or greater douchebag behavior. The term generally only applies to people who are otherwise polite and kind until someone is rude to them first.

(Guy#1) Hey man I can't stand Tommy anymore. He has been such an asshole lately. I think I am going to key his car!

(Guy#2) No don't do that dude. Just because he is a douchebag doesn't mean you have to be a douche-back!

douche backwash 

someone who is the way annoying than your average "joe douchenozzle" and has need for a more insulting insult, because the backwash of the douche is the run off of what actually goes into the skanky, nasty pussy, so therefore calling someone douche backwash is way worse!

Hey, that guy on craigslist with stupid blinder shades flashing 20's and talking trash trying to pickup chicks is nothing more than douche backwash!

Even people all over the net are calling him douche backwash.

Douche-Nozzle Backflow 

A person (typically male) or their actions, who has acted in such an obnoxious manner that the behavior alone reeks as an unsanitary twat would. Malicious intent and/or malevolence is a general added characteristic.

The most vile form of Douche-Baggery. In progression of severity of behavior: One could be a Douche, a Douche-Bag, Douche-Nozzle, or most disgustingly Douche-Nozzle Backflow!

The First Sergeant was not a Douche-Bag, but rather Douche-Nozzle Backflow. His character reeked.
