yada yada yada

Etymology
Probably influenced by (or perhaps an alteration of) or ; perhaps  of ; or perhaps derived from the Norwegian expression  which has a similar pronunciation and interpretation. Sometimes popularly attributed to Yiddish, but this is dismissed by etymologists.

"Yatter, yatter" is British (specifically Scots) English for "continuous chatter, rambling and persistent talk". S. R. Crockett, The Men of the Moss-Hags (1895) xxix: "The woman's yatter, yatter easily vexed me." Yadder is a Cumberland word meaning "to talk incessantly; to chatter".

Various variant forms appear in the US 1940s–60s; for example, the 1947 American musical Allegro by and  contains a song called “Yatata, Yatata, Yatata,” about cocktail party chatter; see talk page for additional citations.

The phrase "yadda yadda" was first popularized by the comedian in his standup bit "Father Flotsky's Triumph," the closing track on his 1961 album "Lenny Bruce - American." It gained renewed popularity in the US in the late 1990s on the television show , where it appears as a catchphrase, initially in Season 8, Episode 19, entitled “”, originally aired on April 24, 1997, which centers on the phrase (in the duplicative “yada yada” form).
