When your notation isn't enough, it's better to make up new numbers on the spot.

'''Has two popular varieties:'''
* Using zillions, skyrillions and other such words as real (but ridiculously high) numbers. Often [[LampshadeHanging lampshaded]].
* Just making up numbers when their correct meaning may be guessed: for example, "eleventy" must be 110.

Of course, there are plenty of ''real'' large numbers ending in -illion, usually formed with boring Latin prefixes - Wiki/TheOtherWiki, as always, [[http://en.wikipedia.org/wiki/Names_of_large_numbers has a list.]]

RidiculousFutureInflation can be a cause of this. Usually a ComedyTrope. Justified when a character really uses another notation, or when he ''has'' to make a number up because what he's describing is even bigger than a googolplex[[note]](the highest rank in the "official" notation compiled by Wiki/TheOtherWiki.[[/note]]. For money, compare ZillionDollarBill and contrast UndisclosedFunds. For units of measurement, compare FantasticMeasurementSystem.

This is not to be confused with the mathematical concept of [[http://en.wikipedia.org/wiki/Imaginary_number imaginary numbers,]] which are far more useful, especially when computing the square root of a negative number, and have very real applications to things like electronic systems.



* ''ComicBook/DisneyDucksComicUniverse'':
** Scrooge [=McDuck's=] fortune is always measured in "fantasticatillions", "obsquatumatillions", etc. -- often ending in "... and sixteen cents" (the page image is an exception).
** In the climax of "The Crazy Quiz Show", Donald Duck's final question (and his UnexpectedlyObscureAnswer) was the following:
--->'''Q:''' How many drops of water pass over Niagara Falls in a week?\\
'''A:''' [[LudicrousPrecision Nine trillion multipadillion, six hundred and eighty-six squadrificillion, fifty octodecimadillion, eight hundred and sixty-three centrifipillion, nine hundred and forty overplusillion, six hundred and five duplicatillion, thirty-three impossibadillion, seven hundred and ninety-one compounded ultrafatillion, three hundred and forty super trillion, fifty-nine duper dillion, twenty-nine billion, seven hundred and fifty million, four hundred and six thousand, five hundred and thirty-three drops]].
* The ninth issue of the ''ComicBook/{{Madballs}}'' comic book published by defunct Creator/MarvelComics subsidiary Star Comics had the villains demand a payment of twenty-seven quillion dollars.
* The fortune of ComicBooks/UncleScrooge is always expressed in this way, as shown in the page picture.

* "Did you know women prefer Old Spice for their men one bajillion times more than ladies' scented body washes? Did you know that I'm riding this horse backwards? Hyah!"
* There's an ING commercial where one man is carrying around a sign that reads 1.2 million dollars which is the amount that he knows he needs to have in order to live comfortably in retirement. His next door neighbor has a sign that says "A Gazillion" to illustrate that he doesn't know what he requires for retirement and thus needs the company's services.

* In ''MyImmortal'', Enoby shoots Snap and Loopin a gazillion times with her gun. [[GunsAreWorthless This only manages to break the video camera.]]
* Parodied and subverted in ''YuYuHakushoAbridged''.
--> '''Sakyo''': $20 billion on the intruders.
--> '''Tarukune''': Sakyo, quit bustin' my balls. Stop makin' up numbers.
--> '''Giles''': A billion ''is'' a real number, sir.
--> '''Tarukune''': I've just been informed that a billion is a real number.
* ''Fanfic/CalvinAndHobbesTheSeries'': Thunderstorm mentions he could make a zillion [[KillerRobot Shadow]] [[MesACrowd clones]] using a portal.

[[folder:Films -- Animated]]
* ''Disney/{{Hercules}}''
-->'''Hades:''' Uh, yeah, Poseidon, about a zillion times...
* In the beginning of ''WesternAnimation/ToyStory'', the wanted poster of Mr. Potato Head shows the "$50 bzillion" reward. Of course, the drawing was done by a six year old boy.
* ''WesternAnimation/TheLegoMovie'': Captain Metalbeard describes Lord Business's office as being on the "infinityth floor" of the Octan Tower.

-->'''Nancy Kendricks:''' Well it's going to be worth a bazillion times that.
* ''Film/WhoFramedRogerRabbit''
-->'''Eddie Valiant:''' We were investigating a robbery at the First National Bank of Toontown. [snip] Anyway, this guy got away with a zillion simoleons.
** Might actually be justified (and not just by RuleOfFunny). "Zillion" might in fact ''be'' a number in Toon, and one wonders if there's an exchange rate for "simoleons".
*** Or you could always spend them in VideoGame/SimCity.
* ''Film/UndercoverBrother''
-->'''The Chief:''' Didn't you cause about a ba-zillion dollars worth of damage?
* ''Film/StarshipTroopers'' (also used in [[Literature/StarshipTroopers the book]]).
-->'''Trooper:''' Bugs, Mr. Rico! Zillions of 'em!
* To modern ears, ''Film/BackToTheFuture'''s famous "1.21 jiggawatts" sounds like this, but it's really just an outdated pronunciation of "gigawatts".
** Either that or the power generated by [[ThePowerOfRock dancing 1.21 jigs]].
* ''Film/AustinPowers'': Dr. Evil holds the world hostage for "1 billion, gagillion, fafillion, shabolubalu million illion yillion...yen". The UN deems it a reasonable price.
** This was a reference to the two previous films:
*** In ''Film/AustinPowersInternationalManOfMystery'', Dr. Evil decides to hold the world hostage for "one ''million'' dollars!" A large amount of money in 1967... not so much in 1997. NumberTwo convinces him to hold the world ransom for the more reasonable amount of "one hundred... ''billion''... dollars." When he calls the UN to give them his demands, he accidentally gives them the one million dollar price and they laugh in his face - and are then shocked when he gives the real amount.
*** In ''Film/AustinPowersTheSpyWhoShaggedMe'', Dr. Evil contacts the White House and demands the sum of "one hundred billion dollars!" He's met with ridicule because it's 1969: there isn't that much money ''in the entire world''. He then gives the one million dollar figure and they predictably panic.
** He also states in the second film "Why make trillions when we can make billions", which [[OnlySaneMan Scott]] proceeds to angrily correct. Seems Dr. Evil just really sucks at both math and economics.

* ''Donald Rumsfeld briefed the President this morning. He told Bush that three Brazilian soldiers were killed in Iraq. To everyone's amazement, all of the colour ran from Bush's face, then he collapsed onto his desk, head in hands, visibly shaken, almost whimpering. Finally, he composed himself and asked Rumsfeld, "Just exactly how many is a brazillion?"''

* ''Not for a Billion Gazillion Dollars'' by Paula Danzinger.
* From ''Literature/TheLordOfTheRings'': Bilbo proclaims, "Today is my 111th birthday: I am eleventy-one today!" The term is apparently normal for hobbits, who live longer than humans. It's derived from Old English: ''hund endleofantig'').
* In ''Literature/LifeTheUniverseAndEverything'', the Krikkit Wars apparently resulted in two grillion casualties.
* ''Literature/{{Discworld}}''
** A conversation in ''Discworld/WitchesAbroad'' between Magrat and a rather bratty Literature/LittleRedRidingHood:
--->"Bet you a million trillion zillion dollars you can't turn that bush into a pumpkin," said the child.
--->"Nothing. Just thinking. And you owe me a million trillion zillion squillion dollars."
** A variation in ''Discworld/TheScienceOfDiscworld'', in which imaginary numbers are parodied with the Bursar suggesting that there's an extra number between three and four called 'umpt'. A StealthPun about 'umpteen', umpt presumably being that minus ten.
* Creator/DaveBarry once proposed that Congress should use the "Whomptillion", defined as "an amount of money so huge that every time a Congressman says the word, your taxes go up 5%".
* In the last RamonaQuimby book, Ramona turns ten, but refers to herself as "zeroteen" because she thinks the way the first three double-digit numbers get left out of the "teens" is arbitrary and unfair.
** In ''Beezus and Ramona'', when she's five, she weighs herself and comes up with "fifty-eleven pounds."

** ''Celebrity Series/{{Jeopardy}}'' [[http://snltranscripts.jt.org/99/99qjeopardy.phtml Tobey Maguire was playing Keanu Reeves]]:
-->'''Alex Trebek:''' [to Keanu] Let's see what you wagered: Eleventy billion dollars. That's not even a real number.
-->'''Keanu Reeves:''' Yet.
** In another episode, Alex threw out the final category and told the contestants to write down any number at all in order to win. Jimmy Fallon's French Stewart went with "threeve" and then wagered "$Texas."
* Parodied on ''Series/ThatMitchellAndWebbLook'', in a [[{{Calvinball}} Numberwang]] sketch where an "Imaginary Numbers" round is played. Somehow, while "Twentington" and "Frilve hundred and Neeb" are accepted, "Shinty-six" (depicted as fifty-six with a reversed five) is rejected as a real number, as in the popular phrase, "I only have shinty-six days left to live."
* Timmy Mallet's children's breakfast show from TheEighties, ''Wacaday'', popularised "squillion". This recently re-emerged when UsefulNotes/NickClegg used it in one of the British prime ministerial debates.
* In the episode "Culture for the Masses" in ''Series/TheGoodies'', Tim buys a painting at an auction for "one million billion quintillion zillion pounds and two and a half new pence", which it goes without saying that he does not have. They leave thirteen pence as a deposit. By ContrivedCoincidence, the National Gallery have all their paintings insured for exactly one million billion quintillion zillion pounds. HilarityEnsues.
* The TV Series of ''Series/TheHitchhikersGuideToTheGalaxy'' extends a line of dialogue from the book and puts in a new number:
-->'''Ford Prefect:''' I think this ship is brand-new, Arthur.
-->'''Arthur Dent:''' Why, have you got some exotic device for measuring the age of metal?
-->'''Ford Prefect:''' No. I just found this sales brochure on the floor. It says, "The Universe can be yours for a mere five quilliard Altairian dollars."
-->'''Arthur Dent:''' Cheap?
-->'''Ford Prefect:''' A quilliard is a whole page full of [[UsefulNotes/BritishEnglish noughts]] [''[[UsefulNotes/AmericanEnglish zeros]]''] with a one at the beginning.
* ''Series/MrShow'' featured a sketch set in the 1890s which revolved around a marching band competition judged by the "Eleventy-Twelfth President of the United States".
* There was a series of sketches on ''Series/{{MADtv}}'' parodying ''WesternAnimation/SchoolhouseRock'' and one of the songs parodied was [[http://www.youtube.com/watch?v=IHYtYE8_bzU&feature=related "Three is a Magic Number."]] The lyrics went like:
-->''3, 6, 9''
-->''12, 47, 90''
-->''Something, next, 100''
-->''3 times 10 is -2''
-->''3 times 5 is elevendy''
-->''3 times 2 is I dunno''
* ''Series/HowIMetYourMother'': "I would bet you a gazillion dollars -- no, I'm even more confident -- I would bet you a ''floppity-jillion'' dollars."
* ''Series/BabylonFive'': "Elventy" is used in one episode, with Lennier mentioning his "eleventy-fifth year" of religious caste training. [[WordOfGod According to JMS]], this is actually an aversion, and "eleventy-fifth" is "sixteenth" as expressed in Minbari base-eleven style (though poor Londo looked as bored as if he ''had'' been listening to 115 years' worth of anecdotes).

* Music/JayZ's "Allure":
--> "The game is a light bulb with eleventy-million volts"
* Music/{{Usher}}'s "Burn" has this:
--> "It's been fifty-eleven days, umpteen hours,\\
I'm gonna be burnin' 'til you return!"

[[folder:Newspaper Comics]]
* ''ComicStrip/CalvinAndHobbes'':
** On a math test, Calvin asks Suzie for an answer, and she responds "three hundred billion gazillion." This is then lampshaded, as Calvin proceeds to snark her for giving such a "helpful" answer. Susie then follows up by saying that it's a 3, followed by 85 zeroes, and Calvin writes it down.
** Spaceman Spiff also tends to use these kinds of "-illion" numbers.
** When Calvin asks Hobbes for help with his math homework, Hobbes notes that it requires calculus and imaginary numbers, "You know, eleventeen, thirty-twelve, and all those." ([[http://en.wikipedia.org/wiki/Imaginary_number Imaginary numbers]], by the way, are a real mathematical concept, [[RightForTheWrongReasons but not the way Hobbes puts it]].)
* ''ComicStrip/{{Dilbert}}'' has "frooglepoopillion".

* ''Pinball/DrDude'' boasts of having {{Pinball}}'s first-ever ''Gazillion'' Jackpot.

* In "The Rain Song" from ''Theatre/OneTenInTheShade'', Starbuck boasts that he knows "forty-'leven different methods" for bringing rain.

* The [[VideoGame/BillyVsSNAKEMAN Eleventy Billionth HoKage]] insists that "eleventy" means "[[LogicBomb eleven more than everything]]"
* One selling point of ''VideoGame/{{Borderlands}}'' was its "87 bazillion" guns. The actual number of weapon combinations is quite high, but doesn't even come close to the "billion" moniker.
** VideoGame/{{Borderlands 2}}: ''"87 bazillion guns" just got [[UpToEleven BAZILLIONDIER]].''
* In ''[[VideoGame/EarthBound Mother 2]]'' (the Japanese Version), Porky's dad claims Ness' family owes him an unrealistic value, something equivalent to "hundred million jillion dollars". In the US version, it was changed to a realistic value of hundred thousand dollars or more. Later in the game, Ness and company acquire a diamond said to be worth a similarly unrealistic value, but the translation made it worth an even one million.
** Inversely, [[YearsTooEarly it is a gazillion years too early]] to oppose [[EldritchAbomination Giygas]]! Well, according to [[spoiler: Porky]], anyways, who used an actual number (not to be taken literally) in the Japanese version.
* When [[WebAnimation/HomestarRunner Strong Bad]], and [[WebComic/PennyArcade Tycho]] argue over whose website gets more hits per month in ''VideoGame/PokerNightAtTheInventory'', [[JerkAss Strong]] [[BadButt Bad]] argues that Tycho's gets about a few blajillion. On Monday, several katillion hits. On Tuesday, [[OverlyLongGag half a blazill-illion.]]

* In ''Webcomic/{{Sinfest}}'', [[http://www.sinfest.net/archive_page.php?comicID=3251 Uncle Sam will sell Lil' Evil the warhead for 900 billion jillion dollars.]]
* In ''Webcomic/{{Homestuck}}'', the [[InfinityPlusOneSword Warhammer of Zillyhoo]] costs one zillion units of Zillium grist to [[ItemCrafting alchemize]].
** Given that John was nowhere near an alchemiter, the "ONE ZILLION" thing was probably just his imagination.
** In Act 6 it's confirmed that the Warhammer and the other Zilly-weapons (plus Dirk's Unbreakable Katana) actually do cost one zillion Zillium each. Of course, all this alchemization takes place during [[SillinessSwitch Trickster Mode]], so who knows whether that number really means anything.

[[folder:Web Original]]
* [[WebAnimation/WeeblAndBob Insanity Prawn Boy]] likes to use the number "fifty-twelve". Incidentally, he lives in apartment 512.
* According to the first episode of ''WebVideo/OuranTheVaguelyAbridgedSeries'', Haruhi Fujioka needs "eight million jillion quadrillion malalalalilion shoo-ba-da-da-do-bop-bop-ian" in order to pay off a broken vase. Also note that value doesn't have a currency attached to it.

** There's a villain who always says he wants a buh-million dollars (denoted as $BUH.000.000).
** In fact, the number "eleventy billon" is thrown around quite frequently, presumably meaning 110×10[[superscript:9]], or 110,000,000,000. Even ''Father'' says it in ''WesternAnimation/OperationZERO''.
* On ''WesternAnimation/ThePenguinsOfMadagascar'', when Kowalski is asked about a number that's less than nothing, he comes up with "neg-finity".

-->'''Shego (pushing SSJ aside):''' Hi, he's new at this. A billion dollars apiece will do just fine.
* The WesternAnimation/DuckDodgers episode, [[Series/TheSixMillionDollarMan "The Six Wazillion Dollar Duck"]] lampshades this completely.

* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' episode "Normal Boy", Jimmy becomes dimwitted and during school he answers a math problem (what's the square root of 144?) with "eleventy-six".
* A couple examples from ''WesternAnimation/{{Arthur}}'': in the episode "Arthur Babysits," he flashes back to D.W. jumping on the couch as Arthur attempts to read to her. She chants "Forty-eleven, forty-twelve, forty-thirteen..." while doing so. Additionally, in the episode "I'd Rather Read It Myself," the Tibble Twins tried to prove to D.W. they could tell time. They pointed to the grandfather clock in Arthur's living room and said the time was "eleventy-twelve," when the clock actually read ten past four.
* ''WesternAnimation/{{Metalocalypse}}'' does this quite often, mainly because each member of Dethklok is at the very least, a multi-billionaire, and each album the Band releases dramatically affects the Stock Market and Global Economy.
-->'''News Anchor''': World markets rose sharply again on the shipping of the Dethklok album, which is expected to give a huge boost to the economy. As a result, the U.S. Treasury issued a new denomination of currency; the Klokillion. That's one million krillions, folks!
* In the ''WesternAnimation/AdventureTime'' episode "Five More Short Graybles", the storyteller informs the viewer that the theme of the episode can't be the five fingers because [[FourFingeredHands nobody's had five fingers for over "20 mabillion glables".]]
* In the episode "Assisted Suicide" of ''WesternAnimation/TheVentureBrothers'', Eros and Thanatos argue over whether "quadrillion" is a real number. (It is. 10[[superscript:15]] in short scale, or 10[[superscript:24]] in long scale.)

[[folder:Real Life]]
* The technical name for a googol, if you were to [[http://en.wikipedia.org/wiki/Names_of_large_numbers extrapolate from the usual naming convention]], would be "ten duotrigintillion", or "ten thousand sexdecillion"/"ten sexdecilliard" on [[http://en.wikipedia.org/wiki/Long_and_short_scales the long scale (where a billion equals one million millions)]], or we could just say 10^100 and call it a day.
** Hilariously, the term was supposedly coined by mathematician Edward Kasner's young nephew upon being asked for a large number.
* TruthInTelevision: [[http://en.wikipedia.org/wiki/Graham%27s_Number Graham's number]] is so ridiculously huge that we have to use [[http://en.wikipedia.org/wiki/Knuth%27s_up-arrow_notation another notation]] to write it.
** If we were to use the normal notation, we'd need a new universe to write it, as this one is entirely too small. For a time it was the largest number ever used seriously in a mathematical proof, though it's since lost this title to other numbers.
*** We would need ''many'' universes the size of this one just to write the number for ''how much too small'' the universe is to write g1, the ''first term'' in an expansion that increases so ridiculously fast that it makes "exponential increase" look like a flat line (to give some idea, the expansion that results in g1 itself starts "3, 7.6 trillion, ..." and there are over 7.6 trillion terms in that expansion alone). Graham's number is g''64''.
** It is so ridiculously huge that the amount of information required to write it down completely in your head is enough to ''literally collapse your head into a black hole''. [[http://www.youtube.com/watch?v=XTeJ64KD5cg&feature=relmfu This video]] gives an idea of how huge it is.
* And, of course, there [[TheWikiRule exists]] an [[http://googology.wikia.com/ entire wiki]] devoted to studying and naming such numbers. Graham's number is on the ''low end'' of the numbers listed there.
* There is an [[http://forums.xkcd.com/viewtopic.php?f=14&t=7469 entire thread on the XKCD forums]] dedicated to creating ever larger and larger numbers. After about 5 pages of this, the numbers being thrown around make Graham's Number seem like a speck of dust in comparison. After another 10 pages... let's just say that the numbers are so large that the math to ''understand'' these numbers gets progressively harder and harder to understand.
** Probably set in motion by [[http://xkcd.com/207/ this comic]]. The [[http://en.wikipedia.org/wiki/Ackermann_function Ackermann Function]] tends to return huge values for even the smallest numbers (Wiki/TheOtherWiki says A(4,3) has 6.031*10^19727 digits). Now imagine Graham's number as the input. "AUGHHH" indeed.
*** Although this number is still provably less than g65, so it's really not actually a huge improvement...
* The S.I. prefixes for large numbers go "tera" (trillion), "peta" (quadrillion), "exa" (quintillion), "zetta" (sextillion), and "yotta" (septillion). People can get very creative thinking up prefixes for numbers larger than these.
** For the next quanitity 1000 times bigger than yotta, the prefix "hella" was proposed. The mass of the Earth, for instance, would be 6 hellagrams.
** You could, theoretically, string multiple prefixes together, so a megayotta would be one million yotta. The [[HiroshimaAsAUnitOfMeasure length of a football field]], expressed in the super tiny unit called the Planck length, would be a little over 5 terayottaPlanck lengths.
* Numbers in French.
** The same principle as "twelve" ("douze") is continued up to 16 ("seize").
** "Seventy" ("septante") has only some rare regional use outside of France. Usually, it's "sixty-ten" ("soixante-dix").
*** Though it's useful to know that only the french use "soixante-dix (70), quatre-vingts (80), quatre-vingts dix (90)" and the rest of french speaking people (Swiss, Belgians and Québecois) use "septante (70), huitante (80), nonante (90)"
** "Eighty" ("octante") is even rarer; the standard French term for 80 is "four-twenties" ("quatre-vingts"). This is comparable to the slightly dated English term "four score".
** "Ninety" ("nonante") is as rare as "seventy" ("septante"). 90, bizarrely, would be "four-twenty-ten" ("quatre-vingt-dix").
* When you get right down to it, since numbers go on forever, all that's necessary is to somehow give those numbers an official name. But until then, numbers like 'zillion' or 'gluglomwomalomadumdummillion' will stay non-existent unless they are given a definition as a specific number.
