俚语，词源有争议。一种说法是来自东欧地区或德国的犹太人名字常常以-ki或-ky结尾，另一种说法是20世纪初大量东欧犹太人移民美国，在纽约Ellis Island移民检查站需签X以确认文件或其它，一些不识字的犹太人认为X代表基督十字架，因此，就用他们习惯的圆圈O代替，O在依地语里面念kaykl,故事传开后，kike就成为犹太人的戏称。
There is no charity organization of any kind here [a small city in Pennsylvania] and, what is sadder to relate, the Jews in this city will not form one; that is, if the present temper of the people can be used as a criterion. The German Jews are bitterly opposed to the "Kikes," as they persist in calling the Russian Jews .... ["Report of the National Conference of Jewish Charities in the United States," Cleveland, 1912]Philip Cowen, first editor of "The American Hebrew," suggests a source in Yiddish kikel "circle." According to him, Jewish immigrants, ignorant of writing with the Latin alphabet, signed their entry forms with a circle, eschewing the "X" as a sign of Christianity. On this theory, Ellis Island immigration inspectors began calling such people kikels, and the term shortened as it passed into general use.
