Hakn a tshaynik (literally "to knock a teakettle"), meaning to rattle on loudly and insistently, but without any meaning, is one of the most widely used Yiddish idiomatic phrases. It is most often used in the negative imperative sense: Hak mir nisht ken tshaynik! (literally "Don't knock (me) a teakettle!"), in the sense of "Stop bothering me!". Modern Hebrew also contains an idiomatic expression of precisely identical meaning.
