"Giaour or Gawur or Ghiaour, written gâvur in modern Turkish (Turkish pronunciation: [ɟaˈʋur], /dʒaʊər/, from Persian: گور‎‎ gaur), is an offensive religious and ethnic slur, which is used by Muslims in Turkey and the Balkans to describe all who are non-Muslim. It was thoroughly used during the Ottoman Empire, when it referred to the Christian population under Ottoman dominion, namely Greeks,[1][2] Armenians, Bulgarians, Serbs,[3] Romanians, and Assyrians. The term is considered highly offensive by Christians in the Balkans."
Just sayin'....
