Blah Blah Blah

"Yami: Blah blah, card games blah!

Pegasus: Blah blah blah, attack mode blah.

Yami: (in horrified disbelief) Blah blah blah?!

Pegasus: (triumphantly) Blah!"

- Yu-Gi-Oh: The Abridged Series, Episode 18

This trope occurs when someone is listening to someone talk and all they can hear is "blah, blah, blah". Usually used for comedic effect, it indicates that the auditor finds the conversation irrelevant, incomprehensible or boring. Or all of the above.

Sometimes the trope is invoked literally: "Sorry doc, but all I heard of what you said was blah blah liver failure blah blah." Occasionally, this is represented visually from one character's point of view as a stream of words that all flow together.

The irate versions can verge on This Trope Is Bleep. The overanalysed may be Trope Name. In some cases, it's Techno Babble.

An older phrase of similar usage from British television is Rhubarb Rhubarb (or, rarely, Rabbit Rabbit). See also Audience Murmurs. May combine with Wall of Blather.

Advertising

 * Two particular instances, in that the blahs are replaced with names of stereotypically male-oriented activities.

Anime and Manga
"Bidoof 1: Bidoof, bidoof bidoof bidoofbi bi bi doof!
 * In Pokémon Battle Dimension, we got a Bidoof making a heartwarming "we must fight" speech to the rest of the Bidoof. Unfortunately, the Pokémon Speak made it sound like this:

Bidoof 2: Bidoof bidoof bidoof doof doof bi!!!

Bidoof 1: BIDOOF!!!

Bidoof 2: Bidoof?!"


 * The second Pokémon movie soundtrack also contained a song actually called "Blah Blah Blah".
 * Azumanga Daioh: For a conversation in English, which we aren't supposed to understand. One of the funniest scenes.
 * In the Western (as in, with cowboys) manga Miriam, an arrogant sheriff's boasting eventually fades into blah blahs before Douglas, the protagonist, ditches him.
 * The same thing happens again later, though this time he's speechifying to the other two protagonists, Card and Joel, about how honest he is (despite the obvious corruption of the law in town). After he leaves, Card says "Now I understand why Douglas couldn't stand talking with him..."
 * Sayonara Zetsubou Sensei has an instance which is likely a parody of the Azumanga Daioh example. Kaere, who pretends to know English, is asked to talk to an English-speaking foreigner. She goes up to him and like Yukari, starts saying "Pera pera." He then gives her a puzzled look and says in heavily accented but perfect Japanese, "That girl's English is terrible." In this case, it seems like the pera pera was what the character was literally saying.
 * In the dub of Sgt Frog, in the New Year's episode, Giroro mocks Keroro's goal for the new year: "Gundam, blah blah blah, Gundam Gundam."
 * In Yandere Kanojo, some characters can use the phrase, "Yada yada blah blah," as information-conveying dialogue.

Comicbooks

 * In Y the Last Man, one of 355's flashbacks has two obnoxious-looking guys in the background whose conversation consists mostly of this..until the N-word is mentioned.
 * In Archie's Sonic the Hedgehog comic, Sonic once fell asleep while listening to one of Sally's speeches--his falling asleep was represented by her speech slowly degenerating into "Blah blah blah blah..."
 * When Hercules is asked what his compatriot (and Teen Genius) Amadeus Cho would do when faced with a brain-teaser, Herc imagines Cho going "Blah blah numbers blah blah math blah blah blah science."
 * In Babymouse Burns Rubber, a Star Wars-esque narrative scroll relates the story thus far, eventually turning into "blah blah blah are you really still reading this?"
 * Occurs in Jhuger's parody of Jack Chick Tracts. "And the Lord Blah Blah Blah Blah Blah Blah Amen!"
 * A scene in Garth Ennis' Punisher: War Zone mini-series not only does this, but also provides a variant that achieves the same effect: Molly secretly listens to a group of Mooks talking and some of the word balloons literally say "Stuff wiseguys talk about" and "Stupid, cowardly, easily convinced wiseguys".

Fan Fiction
"Haruhi: Blah blah blah, Skip the speeches - if I don't know the complete back story, it's all meaningless to me."
 * Haruhi in Kyon Big Damn Hero, when Kyon and Asakura are talking about the time when she tried to kill him.

"Andy: Dear Andy, thank you for purchasing my test, blah blah blah... That's what it says. "Thank you for purchasing my test, blah, blah, blah"."
 * Used in Calvin's epic tirade against the We Will Meet Again trope in Calvin and Hobbes: The Series.
 * Another instance is justified:

Films -- Animated
"Edna (to Helen): Yes, words are useless! Gobble gobble gobble gobble gobble. There's too much of it, darling, too much!"
 * In Cloudy With a Chance of Meatballs, the mayor responds to Flint's explanation about why the food is getting bigger (and potentially dangerous) with, "Here's what I heard: blah blah blah, science science science BIGGER."
 * From The Incredibles:

Films -- Live-Action
"Hedly Lamarr: Give the Governor a harrumph!
 * In The Movie version of Speed Racer, young Speed found his schoolwork turning into blah-blah-blah because it wasn't talking about car racing.
 * In Ernest Goes To School, Ernest becomes much smarter after undergoing a magical intelligence upgrade, but his newfound intellectualism makes his simple classes so boring to him that the lectures all come across as "blah blah blah blah blah."
 * In True Lies, when Harry is translating the Big Bad's villain speech for Helen, he starts giving it as, "We shall triumph over the evil Americans, blah blah blah," as if to imply he's heard it all before. Turns out that's pretty much a direct translation.
 * Mr. Deeds features a woman responding to Winona Ryder's heartfelt apology with "All I heard was blah blah blah, I'm a dirty tramp!"
 * In The Movie of Nine, Guido's wife, tired of listening to his lies, interrupts him with "Blah blah blah blah blah."
 * Blazing Saddles has a pack of the Governor's underlings saying nothing but "harrumph, harrumph." It's immediately lampshaded when the Governor points at one and says, "Hey, I didn't get a harrumph out of that guy!"

Underling: Harrumph!

Gov. Le Petomane: You watch your ass!"

""Excuse me sir, have you ever had your blah-blahed? Is that your girlfriend? Has she ever blahed your blah?""
 * In the Lenny Bruce biopic Bruce there is a sequence in which Lenny (Dustin Hoffman) talks about oral sex to an audience and even police officers. Due to the heavy censorship issues at the time, he told the audience that all profane words would be replaced by "blah-blah". He then continues:

Literature
"Dear Pukenose:
 * Dave Barry, after writing a column complaining about Neil Diamond's songs, in particular a Painful Rhyme in "I Am, I Said," received a great deal of hate mail from irate Neil Diamond fans, which he condensed into this all-purpose letter incorporating most of what they were fuming about:

Just who the hell do you think you are to blah blah a great artist like Neil blah more than twenty gold records blah blah how many gold records do YOU have, you scumsucking wad of blah I personally have attended 1,794 of Neil's concerts blah blah What about "Love on the Rocks," huh? What about "Cracklin' Rosie"? blah blah If you had ONE TENTH of the talent blah blah so I listened to "Heart Light" forty times in a row and the next day the cyst was GONE and the doctor said he had never seen such a rapid blah blah What about "Play Me"? What about "Song Sung Blah"? Cancel my subscription, if I have one."

""Dr. Turing, of Cambridge University, has pointed out that bobbadah bobbadah hoe daddy yanga langa furjeezama bing jingle oh yeah," Waterhouse says, or words to that effect."
 * Robert Sheckley once wrote a story about a space explorer whose specialty is linguistics; he happens to land on a planet of beings whose language constantly changes, until they end up saying "Mun" in a variety of tones, conveyed by punctuation and interspersed with comments in whatever language you happen to read it in. (Sorry, I can't be bothered to search a couple cubic meter of books just to find the title in French.)
 * According to George and Harold's comic books in the Captain Underpants series, their principal, Mr. Krupp, is only capable of saying "Blah blah blah" and "Bwahahaha".
 * From The Dresden Files: After Harry uses this trope, he gets called on it by his friend Michael: "Don't Yadda Yadda the Lord, Harry."
 * In the Cryptonomicon, Waterhouse tries (and fails) to explain how his digital computer works to a much less technically savvy character:


 * Actually occurs in The Bible of all places: Isaiah 28:10 and 13. As translated by the NIV: "Do and do, do and do, rule on rule, rule on rule; a little here, a little there." (Hebrew: "Sav lasav, sav lasav, Kav lakav, kav lakav, Ze'er sham, ze'er sham.") This represents people mocking the prophet's words as meaningless blabber.
 * From an example in How Not to Write A Novel: "He went into his office and began his routine of blah while he admired the same view of blah blah that was just the same as every other day on which blah and like clockwork blah blah until it began to seem as if life was an empty series of meaningless actions."

Live-Action TV
"Buffy: Blah blah, biddy blah, I'm so stuffy, get me a scone."
 * Willow, in Buffy the Vampire Slayer: "Blah blah Gaia. Blah blah moon. Menstrual life-force power thingy."
 * Buffy in an earlier episode interrupts a lecture of Giles's.

"Buffy: Same as all the others. Slayer called. Blah, blah. Great protector. Blah, blah. Scary battles. Blah, blah. Oops! She's dead. Where are the details?"
 * "Fool For Love", researching what mistakes previous Slayers made leading to their deaths:

"Dr. Kelso: Why, I remember back in '68, blah blah blah, nostalgic story. Now get the hell outta my office!"
 * Supernatural episode "Tall Tales" in which we see certain events through the main characters' eyes. Dean's version of Sam ends up nagging him in 'blah's.
 * In the first The Comic Strip Presents episode, "Five Go Mad In Dorset" (a parody of Enid Blyton's Famous Five books), the heroes overhear the villain's goons talking like this: "Blah blah blah secret blueprints, blah blah blah kidnapped scientist..."
 * Malcolm in The Middle: when Lois was ranting about the driver who framed her up for a traffic fine, Malcolm was hearing her clucking like a hen, Reese was hearing her say "blah blah blah", and Dewey was picturing himself in the driver seat, with his mom in the passenger's seat saying "Dewey" over and over again.
 * Scrubs. Note that this is what he actually said.

""I'm just some rebound date to you, aren't I? In a year's time, you probably won't remember my name."
 * "Shoe shopping" is used to similar effect in "My Big Bird." Anytime a girl says "shoe shopping," all men within earshot zone out and hear most likely nothing but "blah blah blah" until someone mentions bras or similar. Subverted later in the episode when Dr. Cox reveals to have gained immunity because of overexposure to his ex-wife, Jordan.
 * On one episode of How I Met Your Mother, Older Ted can't remember the name of the woman he was dating, so for the entire episode she is just referred to as Blah Blah. ("Please, just call me Blah.")

"That's not true, Blah Blah!""

""Blah, blah, blah, I'm an architect. Blah, blah, blah, I don't wear suits. Blah, blah, blah, blah, blah. Wow, an architect.How fascinating. Blah, blah, blah, blah. Rambling architecture anecdote. Blah, blah, something about a bridge. Blah, blah, blah...""
 * In another episode, what Barney heard on the previous night was

"Blah blah blah blah Murray blah blah blah blah, Murray ?"
 * Played with on Arrested Development. A lawyer in a commercial says what sounds like, "You don't need doublespeak; you need Blah Blah Blah!" He's actually saying "Bob Loblaw," and he becomes a recurring character. He also runs a website, the Bob Loblaw Law Blog.
 * Mad About You was another show that used the "this is what the dog hears" version.

"Monk: Ugh, all Dr. Bell wants to do is talk. This is Dr. Bell: "Blah blah blah. Tell me about your mother. Yak yak yak. How does that make you feel? Words words words.""
 * Used twice in the Frasier episode "Death and the Dog". Frasier and Martin start arguing about whether Eddie (the dog) can understand them - we cut to Eddie's point of view where all he can understand is his own name. Later, Frasier and Niles start having a psychiatric debate about Martin - we cut to Martin's point of view, where the only thing he can understand is the word "Dad".
 * Monk, in the episode "Mr. Monk Gets Hypnotized":

"Drew: Blah! Blahblah! Blahblabhblahblahblah, blahblabhalbahblah! (no thought bubble)
 * In a parody of The Sims, The Drew Carey Show has an opening where all the characters are talking in 'blah'. Their thoughts were expressed by pictures in thought bubbles.

Oswald and Lewis: Blah? (thought bubbles are empty)

Drew: I was just kissing Kate and thinking about her at the same time! I'm going to ask her to marry me!

Oswald and Lewis: Ohhhh! Blah! Blahblahblah! (thought bubbles of partying and champagne)"

"Rachel: Well okay, how about four hours in a freezing museum auditorium listening to Professor Pitstains and he's "Hey everybody! Remember that thing that's been dead for a gazillion years. Well there's this little bone we didn't know it had!"
 * Used in Dinosaurs, Earl is watching TV and the dinosaurs are talking to each other. All they are saying is Blah blah blah blah blah blah to one another.
 * In Friends:

Ross: First of all it's Professor Pittain! And second of all, that little bone proved that that particular dinosaur had wings, but didn't fly.

Rachel: Okay, see now, what I just heard: blah-blah-blah, blah-blah-blah-blah-blah, blah-blah-blah, blah, blah."

"Leonard: Are you even listening to me?
 * At one point in Firefly, Mal dismisses what someone is telling him by cutting them off and saying "Jabber-jabber-jabber."
 * In Charmed, Paige was on a date and the guy was so boring that all that she heard was 'blah blah blah'.
 * In Grace Under Fire Grace's boss does this in constantly, especially in pep talks, possibly undermined in that he's usually effective.
 * The Get Me Hennimore! sketches from That Mitchell and Webb Look. In each sketch, Hennimore's boss would give him two straightforward but mutually incompatible jobs, the central Macguffins of which were indistinguishable from each other. Hilarity Ensued. In the final episode, the audience was given an insight into Hennimore's head, where his boss's instructions consisted entirely of "blah blah blah" while he pictured the inevitable and imminent resulting disasters.
 * Happens during an episode of Big Wolf On Campus. Merton tries to explain the plagues of the Old Testament to Tommy (Since a mummy was using them against the high-school kids...long story) and ends up going "...blah, blah, blah." which prompts Tommy to respond "You can't blah, blah, blah the Bible."
 * Web Soup showed a video where a little girl gets kicked in the face with a soccer ball. When the clip ends, Chris Hardwick goes, "Blah Blah Blah, balls-to-the-face joke."
 * On Rescue Me, this is Tommy's sort-of catch phrase.
 * In True Blood, Pam's explanation of a dire situation is: "Blah, blah, vampire emergency, blah."
 * Glee: Mercedes ends up being the third wheel to Kurt and Blaine. Combined with her going into tots-withdrawal, we get: "Gay Gay Gay." Amusingly, it turns out that they were talking about football during her zone-out.
 * On The IT Crowd, when Moss is trying to explain to Jen the basics of computers on her first day, all she hears from him is static.
 * That 70s Show has an entertaining variation: A conversation between Eric, Hyde, Kelso and Laurie takes place, involving Laurie shooting down Kelso's blatant attempts to hit on her. After she leaves, we see that Kelso only heard just enough of what Laurie said to him to string together a few sentences that make it seem like she wants him just as badly.
 * In The Big Bang Theory, this happens when Leonard asks Sheldon for advice about Penny:

Sheldon: Of course I'm listening. Blah blah, hopeless Penny delusion, blah blah blah."


 * A subtle example occurs in a Coupling episode shown through the perspectives of various characters: When Patrick and Sally engage in small talk at an office party, she asks how he got there. In Patrick's version of events, he gives a ridiculously detailed account of the brand and specs of his car. In Sally's version of events, he just says "Car". When Susan shows up they also begin discussing all the food in the spread. In Sally's version each meat has its own type and description. In Patrick's, it is all just sausage.
 * In the 2005 Doctor Who Christmas Special episode, "The Christmas Invasion," Rose is wandering about with her on-again/off-again boyfriend Mickey, whose dialogue eventually literally turns into "yap yap yap yap yap."
 * Mickey is very sarcastic, so it was possible he was doing so on purpose, trying to draw attention to her ignoring him...maybe.
 * In context, he's imitating his grandmother: "She does my dinner on a Sunday, talks about you all afternoon, yap yap yap yap..." Still counts, though.
 * Monty Python's Flying Circus had a number of bizarre animated segments where characters would literally just start saying "blah" over again. Here is one such example (starts at 0:44)
 * There was a famous Seinfeld episode about this trope but called "Yadda-yadda". It involved Jerry believing his girlfriend was cheating on him and using "yadda-yadda" to cover it. For example, she mentioned that she met an ex-boyfriend, she stopped over at his place for a visit and "yadda-yadda", she was late for work the next morning.

Music
""And this is what Old Blevins said to me:
 * The Gershwin song "Blah, Blah, Blah." Half the refrain is made of cliched rhymes used in Silly Love Songs of the early 30s, and the other half is "blah blah blah" and "tra la la."
 * The Austin Lounge Lizards perform a song called "Old Blevins", in which the song's narrator meets the eponymous individual in a bar, who seems to have some deep and abiding wisdom he's desperate to share:

He said "Blah blah blah blah blah blah blah blah

In Tijuana, blah blah blah, back in 1963...""

"When you talk, all I hear is "blah blah blah"
 * Rockapella also performed a song entitled "Blah Blah Blah":

Baby, you got nothin' to say

You're makin' sound good and loud now, I can't make it out

Your lips are workin' fine, but when you talk, "blah blah""

"We bankrupt all invaders, we sell them souvenirs
 * The second verse of the Ankh Morpork anthem:

We ner ner ner ner by the ears

Er hner ner ner ner ner ner ner hner ner ner.

Ner-ner her, ner-ner ner,

hner ner ner ner neeer

Er, your gleaming swords, we mortgaged to the hilt...

We mortgaged to the hilt"

"I'm walking to the something, blah blah blah blah blah blah blah (collapse)
 * The reason for all the "ner"s is that the writer of the anthem knew that no one remembers the second verse of an anthem anyway, so there was no reason to write a full second verse.
 * In the song "Don't Worry 'Bout a Thing" by the country music group SHeDAISY, the bridge is actually composed of a string of "blah blah blah"s.
 * In Biz Markie's "Just a Friend", he refers to the girl as "Blah blah blah".
 * "Sayin' blah blah blah, just jackin' their jaws" from Montgomery Gentry's "What Do Ya Think About That."
 * "She said, 'bienvenidos, señor, blah blah blah blah'" from Blaine Larsen's "I Don't Know What She Said."
 * Gorillaz, "Rockit":

I'm drinking too much blah blah, blah blah blah blah blah blah (fall out)

I'm feeling very blah blah, I want to blah blah blah (collapse)

And in the end, it means I blah blah blah blah blah blah blah (the end)"

"Babble babble bitch bitch
 * Little-known group Devotion 2 Music provided the song "Blah, Blah, Blah" to the Pokemon the Movie 2000 soundtrack, which basically boils down to a group of girls who don't care what adults have to say, they're too busy playing/watching Pokemon.
 * Kesha wants you to stop ta-ta-talkin' that blah blah blah.
 * De Doo Doo Doo De Dah Dah Dah, they're meaningless and all that's true.
 * "Yakety Yak" by The Coasters.
 * There was a song by Gigi D'agostino titled "Bla Bla Bla", which consists of pure gibberish. It's got some cool animation though.
 * Slovenian rock band Naio Ssaion has a song entitled "Blah-Blah."
 * "This is the New Sh*t" by Marilyn Manson is all about this trope. The chorus even mentions it:

Rebel rebel party party

Sex sex sex and don't forget the "violence"

Blah blah blah got your lovey-dovey sad-and-lonely

Stick your STUPID SLOGAN in:

Everybody sing along."

"Twinkle, twinkle
 * The Minutemen mock the typical content of Silly Love Songs in "#1 Song", which ends with:

Blah blah blah

E! T! C!"

"And the people, they go 'blah blah blah, blah blah blah'"
 * One children's song, The Animal Sounds Song, gives a list of animals (including people) and the sounds they make.

Newspaper Comics
"Evie: Everything ok at home, Val?
 * The Far Side with a dog translating machine. The translations? Strings of "Hey! Hey! Hey! Hey! Hey!"
 * Robotman also did a similar one, with the dog's barking translated as "Fleas, fleas, tail, fleas..." and the cat's meows as "Ball, ball, chase ball, tuna..."
 * Another pair of The Far Side strips show how a dog named Ginger hears her owner ("blah blah Ginger blah blah blah blah blah blah blah blah Ginger blah blah blah blah blah...") and how a cat named Fluffy hears hers ("____________________________________").
 * Inverted in one FoxTrot comic, which has Paige complaining that the day has been boring, and it's just been one "blah" event after another. Cue Peter walking up to hear her actually say "blah blah blah" out of the legitimate context Paige had been using.
 * This strip was possibly Amend lampshading, as early strips involved Paige's phone conversations literally written as "Blah blah blah blah blah".
 * From a Stone Soup strip:

Val: We're fine. Weather's nice... the girls can't wait for summer... Phil and I are seeing more of each other... blah blah blah...

Evie: "Blah blah blah"?? I haven't heard that euphemism in quite a while.

Val: I haven't needed that euphemism in quite a while."

 * One scene of Rodgers and Hammerstein's Allegro has the Greek Chorus continuously chanting, "Yatata, yatata, yatata, yatata" to represent what "the deep-thinking gentlemen and ladies who keep this metropolis alive" have to say to each other. Or, in other words:

A Man (Answering in the same gushing manner): Hogwash!

Man (To Girl): Balderdash!

Another Man (To Another Girl): Phoney baloney!

Girl (Answering): Tripe and trash!"

"Clerk: Blahblahblahblahblahblahblah... truth... truth... truth. Selp-yuh God."

Videogames

 * In Vampire: The Masquerade Bloodlines, the hostess at the Red Dragon restaurant calls her friend on her cell phone after you take the elevator to the second floor. One of her conversations consists of nothing but "Blah blah blah" with inflection and emphasis in the right places to make it sound like it could be an actual conversation.

 * From the first Sly Cooper game:


 * In Luminous Arc 2, Pop use this to get over with.

 * In Yahtzee Takes On The World, by yes, that Yahtzee, Newspapers have only the title (I.E. the important part) in actual words, with the rest being just the word "blah" repeated over and over, but one random word will also be added, so the paper reads something like this:

"Terumi: Well, since you're all here, I may as well tell you the same story I've told everyone else today. Blah blah blah, CAULDRON, blah blah blah, BLACK BEAST, blah blah blah, AZURE, blah blah blah, NEW WIFE, blah blah, HURRAY! The end!"

Web Originals
"What Kyon Hears: "Blah, Blah, Blah. I'm a selfish jerk. Blah, Blah, Blah. Pay attention to me. Blah Blah Blah. I have delusions of godhood."
 * Used in one of the original Lonely Girl 15 'trailers', YouTubers Secret Language.

 * Parodying the YGOTAS example above, there's part of this Randomdce video.
 * RWBY: Professor Port's first lecture early in the series fades into literal "blah blah blah" as the camera focuses on Weiss's growing irritation with Ruby's behavior.

Western Animation
"Toph: "You know what I just heard? Blah blah spiritual mumbo jumbo blah blah something about space.""
 * The Fairly Odd Parents has this with "untranslated" girl talk: "Blah blah blah shoes! Blah blah blah clothes! Blah blah blah boyfriends! Blah blah blah. We'll never notice you."
 * Taz's dad (a Bing Crosby Soundalike) from Taz-Mania often went "Blah, blah, blah, yakkety schmakkety."
 * Ed, Edd n Eddy:
 * In the Rashomon episode "Once Upon an Ed", all Edd can say during Ed's flashback is things like "Yap yap, blah blah, drivel drivel drivel".
 * In "Boys Will Be Eds", as the boys suddenly find themselves infatuated with Nazz, her angry tangent about them making fun of Jimmy's Amusing Injuries trails off into "blah blah blah".
 * The adults on Peanuts and their muted trombone-larynges would probably count as another perceptual equivalent to blah.
 * Avatar: The Last Airbender:

"Aang: "Firebenders...Fire Lord...blah, blah, blah, blah.""
 * What about:

"Mung: Listen, Chowder. Late night snacking is not healthy. It can cause a change in your eating and, blah. Blah blah blah blah blah. Blah, blah blah blah. Blah blah. Your not listening to me are you?
 * When Bart tries to train Santa's Little Helper in The Simpsons, that's all the dog hears.
 * The same happens to Bart and Homer themselves, when speaking to a teacher and a psychiatrist about Bart's bad performance in school.
 * Similar to The Simpsons, Rugrats once had an episode with dog's-eye-view scenes, where all the humans speak gibberish except for the dog's name, Spike.
 * In a flashback, Young!Krusty also invoked this trope when poking fun at his father's profession as a Rabbi ("Blah, blah, blah, Moses!").
 * In an episode of Duckman, during a visit to a Banana Republic, the titular character embarks on one of his trademark rants, and gains a number of listeners. When the perspective shifts to one man in the crowd, he hears it as "blah-blah-blah" and thinks "I wish we understood English."
 * One episode of Family Guy showed a "clip" from Murphy Brown in which the dialogue consisted of this and the name of some 1990s political figure. ("Blah-blah-blah John Sununu." "Blah-blah-blah Dan Quayle." "Murphy! You can't Blah-blah-blah the Ayatollah!" and so forth.)
 * The trope did happen in an episode of Murphy Brown as well: Murphy speaks to Frank, and all he hears is a loud noise that sounds like a foghorn.
 * More Family Guy - there's a bit about how to craft "perfect Star Wars dialogue," which consists of saying "something, something, something, Dark Side, something, something, something complete".
 * And Something, Something, Something, Dark Side was used as the title of their spoof of The Empire Strikes Back.
 * An episode of the animated Beetlejuice series had a scene where Lydia is sitting in class, listening to her teacher literally say "Blah blah, drone drone..."
 * Farmer John often starts talking like this in Sheep in The Big City. At one point he goes on like this for an entire night, then says: "I guess I should stop saying "blah" over and over again and get going".
 * Chowder once had the title character listening to Mung Daal's lecture about midnight-snacking:

Chowder: Yes I am!

Mung: What'd I just say?

Chowder: Blah, blah blah. Blabbty, blah blah. Blah blah. and I couldn't hear the last part because I was looking at the food.

Mung: ...Lucky guess"

"Patrick: Blah Blah Blah Blah Blah! Blah Blah Blah Blah Blah! Blah! Blah! Blah! Awloooooooo-
 * Another episode shows Endive reading a fake love letter saying how beautiful she is, but when you see it all it says it "Dear Ms. Endive" then repeats blah for the entire page.
 * Which implies that Mung actually wrote blah blah blah for almost an entire letter. Then again, she does have an obsession with him in that episode, so apparently she was crazy enough to fill in the blanks for herself and pretend he actually wrote them.
 * In "Chowder's Catering Company", when Chowder arrives in the kitchen with a dirty fuzzball, we see Mung talking to Shnitzel, although we can only hear him say "blah blah blah".
 * Parodied in SpongeBob SquarePants. Spongebob lets Gary sleep over at Patrick's rock house, and while he's thinking, Patrick can only be heard saying "Blah blah blah." Then, when Spongebob leaves, we get to hear the rest of Patrick and Gary's conversation:
 * The same thing happens in "Band Geeks". The ambient noise of everyone talking before practice is revealed to everyone just saying blah blah blah.
 * A similar thing happens in a different episode when Spongebob calls Squidward on the phone. We hear Squidward's half of the conversation, with Spongebob talking in muffled gibberish in the background. When Squidward hangs up, the scene switches to Spongebob and Patrick, still talking in gibberish to each other.
 * Same thing whenever Mrs. Puff is teaching and Spongebob is distracted. Even when focus switches back to Mrs. Puff she is still saying 'blah blah blah'.
 * Also in one episode where Sandy calls Spongebob's decision to forever stay in his house 'crazy talk', Patrick interrupts and says that this is the "real" crazy talk:

(Sandy bonks him on the head)

Patrick: Sorry."

"Aquaman: Uh, what about the plan?
 * In the season 6 episode 'The Card'; Spongebob is trying to explain to Patrick how valuable his trading card is, but all Patrick could hear is 'bla bla bla'.
 * "Heh-heh, Rob Schneider, derp de derp! Derp de derpity derpee derp." From an episode of South Park, it's a Real Trailer Fake Movie for "Da Derp Dee Derp Da Teetley Derpee Derpee Dumb" (rated PG-13).
 * "Derp" is a nonsense word that Matt Stone and Trey Parker invented while they were working on Cannibal!: The Musical which they use in regards to things they think are really stupid. There was even a guy on South Park whose name was Mr. Derp. Now a part of the internet's vocabulary.
 * Let's not forget "RABBLE RABBLE RABBLE", which is yelled by pretty much every angry mob on the show.
 * The "RABBLE RABBLE RABBLE" gets lampshaded ocasionally.
 * In the Daria episode "Depth Takes a Holiday", Valentine's Day and St. Patrick's Day are eavesdropping on Helen and Jake chewing out Daria. Valentine's describes their conversation as "being all blah blah blah".
 * In an episode of Pinky and The Brain, we see how Pinky hears Brain, and it basically comes out to "And now we're going to blah blah big word blah blah really big word blah blah blah..."
 * In a holiday edition The Boondocks, Granddad completely waves away Huey's detailed explanation about Christmas actually being a pagan holiday with the hilariously out-of-context line, "Blah blah gay sex, blah blah Congress."
 * In the Batman the Brave And The Bold episode "Journey to the Center of the Bat!", the death of his faithful steed (and prolonged exposure to Aquaman) causes the normally reserved Atom to completely flip out:

The Atom: Blah blah blah! Let's punch 'em!"

"Jay Sherman: Oh no! The Reverend Al Sharpton!
 * Played in every single Humf episode when it's an adult talking to another adult or over the phone.
 * Master Shake's singing of a Christian song: "Blah blah, wine, blood"
 * In Care Bears: Share Bear Shines, Share is trying to convince Princess Starglo not to abandon her post by telling her the storybook version of her history. "You were the first twinklet, the mother of all the stars!" Starglo is not impressed, as she continues the story, "The keeper of starlight and wishes, burning brightly in the sky, blah blah blah blah. Yeah, I've heard the story, too." Though she does admit that the story is true, "Except for the 'blah blah blah' part. I made that up."
 * Phong's password on Re Boot was "yadda yadda yadda".
 * Played straight in Jackie Chan Adventures. "Do my words sound to you like Blah blah blah blah?"
 * An episode of Jimmy Two-Shoes has Jimmy trying to listen in on a conversation between Beezy and Heloise. Even when he's right next to him, all Beezy says is "blah blah blah".
 * Pepper Ann frequently heard teachers this way.
 * In an episode of Histeria about Samuel Webster and his dictionary, the publisher is dictating a letter to his secretary and ends with "blah blah blah blah blah". When asked to read back the letter, she reads the blah blah blah blah blah" back as well.
 * The Critic had an episode where Jay Sherman was playing an arcade game called Escape From the Big Apple in which his player character encountered a rather difficult enemy:

Al Sharpton: Blah blah blah blah blah blah blah blah blah blah blah blah blah-

(Character withers away to a skeleton, then dust)

GAME OVER"


 * On Courage the Cowardly Dog Eustace sometimes says this when something doesn't interest him.
 * The "from a character's perspective" version in parodied/subverted by Phineas and Ferb. Candace is ranting at the two main characters, when they start to phase out. When Candace asks if they were even listening, it turns out that her voice literally became echo-y, for some reason.
 * Invader Zim: "Yes, yes, you blame me for your horrible life, blah, blah, BIG DEAL!"

Real Life

 * This parody of technical presentations.
 * The ancient Greek version of "Blah blah blah" was "Barbari," and this was typically how foreigners were represented as speaking: One long string of unintelligible "bar-bari-bar-bari." Hence the term "Barbarian."
