kibitz (v.) Look up kibitz at
"a looker-on," 1920, from kibitz (v.), American English, 1915, from Yiddish kibitsen "to offer gratuitous advice as an outsider," from German kiebitzen "to look on at cards, to kibitz," originally in Rotwelsch (thieves' cant) "to visit," from Kiebitz, name of a shore bird (European pewit, lapwing) with a folk reputation as a meddler, from Middle High German gibitz "pewit," imitative of its cry. Young lapwings are proverbially precocious and active, and were said to run around with half-shells still on their heads soon after hatching. Related: Kibitzing. Also see kibitzer.
