The person you see walking down the street sporting a hot girlfriend who is way out of his league. The fact that he is porking her makes him a douche-nozzle.

To be a creator of douches or to be the god of douche bags as well as being completely full of themselves. Only a select few have been able to claim this title.

The most extreme level of douche. This person has gone way beyond a douche, beyond a douche nozzle, all the way to a douche nozzle sucker.

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!
