A unit of measurement for use with a douchometer in calculating the precise level of douchism a particular object or potentially douchebaggish person may exhibit. Part of the standard metric system, especially when used in places that use the metric system.
I can see you clearly through my douchometer, and you're registering at least 6500 Douchensteins.
A particulary frustrating and obnoxious person who exhibits douche-like qualities, for whom other insults just don't capture the essence of his assinine-ness.
The act of being an absolute, over-the-top douchebag, using excessive levels of dickishbehavior accompanied by a complete and utter disregard for human decency.
Did you justsee that guy cut in line and then start bad-mouthing the barista? The levels of douchestickery are off the charts here!
