Alternate spelling: doucherie (archaic)
"When you turned on me in that meeting - that was some serious douchery."
"Forsooth, latent asshole, thou hast wandered oft through the land of doucherie, where politician weaves his tale and pigeon doth shit on thy head."
- Lord Elbenworth
Unlike full-blown douchebaggery, mere douchery does not provoke sufficient passion in the observer to make the two hard consonants in the middle of the word worth the effort.
Joe: Nah man, that's just a fake.
Jack and Joe: <sigh> Douchery...
