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.
