From the guy who wrote it.

Check out the "Hobo Code" page.

A hobo is a migrant worker in the United States. Hoboes, tramps and bums are generally regarded as related, but distinct: a hobo travels and is willing to work; a tramp travels, but avoids work if possible; and a bum neither travels nor works.

A nicely designed list of the words of the year. Seems like half are from the election. Can't say I've ever heard of a "fish pedicure," but there it is.
