A jew, in a racist, discriminatory sense. According to Wikipedia, the term "kike" was at first a discriminatory word used by Jews who lived in Western Europe (France, UK or Germany) to refer to those who lived in Eastern Europe (Poland, Romania or Russia), whose family names often ended with "ki". The term was later used by Christians and non-Jews against the whole Jewish population, so the term became a general ethnic slur against Jews in general.
Example: 1.- Mr. Manilowski did it, huh? Must be Polish, that damn kike...
2.- You're going to Auschwitz, you fucking kike!
kike means "Cockroach" in Arabic meaning they are everywhere you cant get rid of them you hate their breed and want to eliminate it out of its existence. therefore jews are reffered to as "kikes"
A derogatory term for a Jewish person. The term originated amongst American Jews in the early 20th century as a slur against Eastern European Jewish immigrants, but somehow became mostly used by anti-Semites as a slur against all Jews.
