From the publisher website:

An attention-grabbing, thought-provoking exploration of the life of the word "asshole," by a renowned linguist and author

It went from the mouths of WWII servicemen to the typewriter of a young Norman Mailer. By the 1970s it had become a staple of Neil Simon plays and Woody Allen movies. In 2000, George W. Bush accidentally uttered it on a live mic and sparked a debate as to whether that made him a man of the people, or just an asshole. Ours is the age of assholism. 

There may be no more assholes in the world now than there ever were, but there are new ways for acting like one. And no less important, we've made the asshole the object of obsessive collective interest, in the way that the phony was in Holden Caulfield's day or the cad was in Trollope's. Over time, the word has become an expression of contemporary American values— about civility, about relationships, about pretension, about class. Yet the media are obliged to bleep it or disguise it with asterisks. And we use it unreflectingly and give it no attention. Considering how important it is to us, it doesn't get the respect it deserves. Until now.
