What a wonderful word. And it's a word I employ frequently. Yes, I seem to be beset with douchebags at every turn these days. As John Mayer writes, there's just something extra satisfying about the sound of the word. That long "ooo" sound connotes "fool", yet the word is so much funnier and more savage.
A thousand curses upon YouTube for not having the Buck Henry "Lord and Lady Doooochebag" sketch from SNL (though I suspect NBC may be to blame).
