On "Seinfeld," the three-word phrase that gives its name to the episode about a woman skipping story details is "yada yada yada."
In season 8's "The Yada Yada," George's girlfriend Marcy uses the phrase to summarize parts of her stories. George becomes suspicious that she is using it to conceal sex with her former boyfriend, but the missing details turn out to involve other secrets, including shoplifting. The phrase also causes trouble for another couple when a man uses it to omit details about a meeting with Elaine, leading his partner to assume he was hiding an affair.
The expression itself predates the episode and was already used in American comedy and conversation to mean that intervening details have been omitted. Seinfeld helped make the phrase especially recognizable to a mainstream television audience. The episode aired on April 24, 1997, as the 19th episode of season 8. It is often confused with generic expressions such as "blah blah blah," but the canonical title and recurring phrase are specifically "yada yada yada."
