2. The action performed by a douche bag
See douche bag:
1. A person who does, says, acts idiotic
Ex. cutting you off without a turn signal; flicking your cigarette butt at someone; deliberately walking into traffic
One would recognize 'douchebaggery' by the way in which one speaks, dresses, walks, or behaves around other human beings.
I have had it with all of your douchebaggery!
"I feel bad for laughing at that" " Don't worry,laugh if you will, for there is no douchebaggery to be found."
