Noun The act of throwing a person or thing out of a window; immediate dismissal or expulson (as from a public office).

Etymology: 17th century. From the Latin de (away from; off), fenestra (window). This word has a funny little tale of origin. It was invented for the "Defenestration of Prague," three men were thrown out of a castle window into the moat by Protestant radicals, marking the start of the Thirty Years War (read more about its origins on dictionary.com).
