"Yada, yada, yada” was popularized by an April 24, 1997 episode of the New York City-based television sitcom Seinfeld. The 1947 Oscar Hammerstein II-Richard Rodgers musical Allegro contained a song called “Yatata, Yatata, Yatata,” about the nonsensical talk at cocktail parties. The origin of the nonsense term is unknown—perhaps it has its origins in “yatter.”
The repeating of terms such as “blah blah blah” or “yeah yeah yeah” dates much earlier than 1947. “Yap, yap, yap” is a similar form with a meaning of “talk, talk, talk.”

From the Show: Allegro 1947 (S)
Yatata, yatata, yatata, yatata,
Yatata, yatata, yatata, yatata,
I’m busy as a bee!
I start the day at half-past one.
When I am finished phoning
It’s time to dress for tea.
Nothing I have to do gets done!
(The deep-thinking gentlemen and ladies
Who keep a metropolis alive
And knock tails
Ev’ry afternoon at five.) (...)

The great and only game of yap, yap, yap, came to a fitting climax when the Foreign Relations Committee of the Senate asked the President of the United States how old he was, where he was born and why, and if he could read and write. Well no, they didn’t ask exactly these questions, but they only skipped a few such.

For we are telling no secret when we say that the candidate at the microphone stumbles through words that somebody else wrote. Fifteen minute periods of yatata are interminably dull without the exercise of the subtlest radio art.

For Mr. Rodgers and Mr. Hammerstein are able composers in any vein, and they have some notable numbers for the modern portion of their play. “Money Isn’t Everything” is a skillful satire of materialism,; “Yatata, Yatata, Yatata” is a savage cartoon of cocktail parties,...

Mr. Rodger and Mr. Hammerstein have written two clever songs for the second act—“Yatata, Yatata, Yatata,” which is a savage cartoon of the barbaric social function known as the cocktail party, and “The Gentleman Is a Dope,” which is superior blues music.

The dialogue sounded like “yatata, yata, yatata.” (...) It just went on “yatata, yata, yatata.” Try it yourself sometime unless this warning cures you of the habit of cocktail parties.
