Used as a disparaging term for a Jew. a very offensive word for someone who is Jewish. Do not use this word. (Probably from kiki, from -ki, common ending of names of Jews from countries in Eastern Europe)
() Possibly from Yiddish קײַקל (kaykl, “circle”). (In the early 20th century, Jews immigrating to the Americas would sign papers with a circle instead of an X—the more common practice amongst non-English speaking immigrants.)
