UrbanDictionary.com, a user-created online dictionary of modern slang, attracts more than 200 million visitors a year. Called "unruly but surprisingly useful" by the New York Times, the site makes it easy for coworkers to learn what "laborhood" means, lets college students debate the definition of "crunk," and provides a discreet way for boomers to discover what "xio" stands for. Culling from the popular Web site, the Urban Dictionary 2013 Day-to-Day Calendar gives readers each day one of the funniest, wittiest, and most provocative phrases.
