Their questions, which I'm going to combine into one question, are about the expressions " yada, yada, yada" and " blah, blah, blah." " Yada, yada, yada" is a phrase used to refer to things that are too boring to repeat.
In a more formal setting, you may say something like, " and so on and so forth." " Yada, yada, yada" and " blah, blah, blah, " when used in a conversation, often have a somewhat negative meaning.
"The Yada Yada" is the 153rd episode of the American NBC sitcom Seinfeld. The 19th episode of the eighth season, it aired on April 24, 1997. Peter Mehlman and Jill Franklyn were nominated for an Emmy for Outstanding Writing in a Comedy Series in 1997.
