1927, from Yiddish kibitsen “to offer gratuitous advice as an outsider,” from German kiebitzen “to look on at cards, to kibitz,” originally in 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.
