The act of someone being an absolute cunt. It's an art perfected by only the most supreme douchebags. It encompasses being a tool, a dick, an asshole etc. Carrying out ridiculous actions that make you a definition douche. Similar to faggotry.
The level of douchebaggery Derp just showed when he caved on my pillow is unreal. I didn't know he was that much of a tool.
Nick Bilton, whose March 10 article in the New York Times managed to explain how to be a digital/electronic douchebag for the audience of the New York Times.
Nick Bilton, of the New York Times, is such an utter douchebag that, in a section of the country and a social class noted for its production of douchebags, he is an instructor of others in how to extend douchebaggery to the digital realm.
An event or act performed by a douchebag. This event or act will negatively impact a particular situation, can involve multiple douchebags, and take the acts of non-douchebags but collectively result in a douchebag situation. An act of douchebaggery will likely result in the creation of a new douchism for describing such act. Example:
As the meeting drew to a close, the various dignitaries could not resist the opportunity to provide closing comments. As these comments drug on and extended the meeting, each person who spoke tried to be more dignified than those previous. The resulting unprepared speeches contained douchalogies and went from an otherwise typical meeting towards a collective douchievement thanks to all of the douchebaggery.
