Defenestrator

Defenestration is the act of throwing someone or something out of a window. The term was coined around the time of an incident in Prague Castle in the year 1618 which became the spark that started the Thirty Years' War. This was done in "good Bohemian style", referring to the defenestration which had occurred in Prague's New Town Hall almost 200 years earlier, and on that occasion led to the Hussite war. The word comes from the Neo-Latin de- and fenestra.
