->''I honestly wonder if at any point in time during the animation someone said "Yes, good job, but you can do better. Make them sag more". Someone get the witch some Duct Tape!''
-->-- '''Youtube comment''' on the Witch in ''WesternAnimation/TheThiefAndTheCobbler''

The act of drawing a female character with unusually large and buoyant breasts and [[{{Vaporwear}} without a bra]], then animating every individual jiggle, sway, bounce and bobble they undergo. Also known as Gainax Bounce or the Gainax Bounce Effect.

The motion so displayed is typically asynchronous -- each breast is animated separately and possesses its own individual movement.

The term was coined by fans some time before 1993 and makes reference to the anime production StudioGainax, many of whose earlier releases made use of this particular variety of {{fanservice}}. According to a Usenet post from 1993, one particular busty young woman from the Gainax anime ''OtakuNoVideo'' inspired a tongue-in-cheek unit of measurement for {{Gainaxing}}: one full bounce is apparently equal to one "MistyMay".

When a male does it, it's a PecFlex.

For a live action TV series built around this trope, see JiggleShow. For real-time generation of jiggling movement in videogames see JigglePhysics.

Do not confuse this with a GainaxEnding - there it's the individual parts of the viewer's brain that gets contorted in different directions.

[[folder:Advertising]]

* Bizarrely, advertisements for the UK insurance comparison website "Confused.com" do this very often, such as in [[http://www.youtube.com/watch?v=6nAvUKPMExc this advert.]] [[http://www.youtube.com/watch?v=4D15De1Ai6A And this one.]] [[http://www.youtube.com/watch?v=nZH6kslt30Y Oh, and this one.]] [[http://www.youtube.com/watch?v=tSZY72Hz9YA Whoops, almost forgot this one.]] And yes, they do get weirder and more overt each time. Especially odd because the main character evolved from a head-and-shoulders mascot with no apparent gender whatsoever.

[[/folder]]

[[folder:Anime & Manga]]
* The whole trope can pretty much be summarized by 300 boobs in 2 minutes, in this [[http://www.youtube.com/watch?v=yBQmh2wJTbA gloriously NSFW AMV]]. [[http://www.animemusicvideos.org/members/members_videoinfo.php?v=162704 And here you can download the original from animemusicvideos.org]].
* Parodied in ''JungleWaItsumoHaleNochiGuu/Hare+Guu'' in which Gupta thinks back to an anime he saw. [[http://danbooru.donmai.us/post/show/531741/bounce-breasts-brown_hair-city-gif-hairband-jungle see for yourself]] (NSFW).
* Plentiful in ''{{Gravion}}'' (which provides this page's picture), especially with [[MsFanservice Mizuki Tachibana]], who bounces considerably with the slightest movement, even ''swallowing''.
** Gainaxing is a signature of Gravion's creator, Creator/MasamiObari, present in his works, including the ''VideoGame/FatalFury'' anime adaptions and ''VideoGame/VoltageFighterGowcaizer'', in which it's put to the utmost extreme.
* ''Anime/CowboyBebop'' has the character Faye Valentine, who is breathtakingly beautiful with gigantic pneumatic breasts that seem to have minds of their own. Canon indicates that she does this on purpose [[DistractedByTheSexy to distract men]]. On one occasion, she wears a perfectly normal evening gown.
* The seventh ''OnePiece'' movie had the girls bounce from doing absolutely ''anything''. Hell, in a few scenes, Nami will simply be standing around, perfectly still, and her boobs will just randomly bounce quite forcefully all on their own.
** Used again slightly more subtly during the Spa Island {{Filler}} Arc. Also [[StupidSexyFlanders Chick Ivankoff]]. In the latter case, wheter it's {{Fanservice}} [[AttractiveBentGender or]] [[BrainBleach not]] is up to you.
** Used later in the Marineford Arc with scenes of Hancock's boobs bouncing every time she moved around.
** Also used in the tenth ''One Piece'' movie when Nami runs down some stairs.
* ''{{Gunbuster}}'' (called [[FanNickname "Bustgunner"]] by some fans) and ''OtakuNoVideo'' from Gainax are the two productions which allegedly inspired the term.
** Perhaps ironically, ''Gunbuster'' actually features what can be considered ''as close to realistic as possible'' physics for the bouncing breasts. Noriko's bounced so much mainly because she moved around a lot even when she wasn't wearing a bra.
* Just about any female character in the various ''BurnUp'' animes.
* Happens a few times in ''{{Slayers}}'', with the leading contender being the [[GagBoobs balloon-breasted]] Naga the Serpent. Surprisingly, Amelia, one of the protagonists, is quite busty (to the point that [[ACupAngst Lina]] hates her for it), but she isn't subjected to this trope, save for the ''[[NonSerialMovie Slayers Premium]]'' movie, where it's actually used as a part of her [[{{Flanderization}} flanderized]] [[TheChewToy chew toy]] status. Newer anime seasons also made up for this by having Amelia be subjected to breast-squeezing CombatTentacles in one battle, and then having her [[TheissTitillationTheory tunic partially ripped from her breasts]] after another battle.
* Mune-mune in Gainax's ''Anime/AbenobashiMahouShoutengai'' is a deliberate parody -- right down to her name, which actually translates as "Tits-Tits".
** [[{{Squick}} And she's]] [[spoiler:[[FanDisservice the main character's]] ''[[DeadAllAlong late grandmother]]''.]]
* Kurono Kurumu in ''[[RosarioToVampire Rosario + Vampire]]''. The movement of her breasts even produces audible sounds! And in episode 4, Kurumu's fat stalker (or rather, his belly).
* Chapter 95 of the manga ''{{Mx0}}'' plays this trope for satire with a magical liquid that makes some (already extremely buxom) girls' breasts experience only 1/6 normal gravity. The result is a ''lot'' of bouncing, first from falling, then from wind, then an earthquake.
* ''Manga/ToLoveRu'' seems overly fond of this. Espically Lala. Just watch the OVA opening, 1 minute and 30 seconds of pure bounce.
* Every female character that appears in the various ''RanmaOneHalf'' motion pictures -- even the ones who are supposed to be small-breasted. This contrasts with the main series where they never seem to move at all, since the show is kind of old and didn't have a huge budget.
** Especially since the characters are considerably ''less'' endowed in the television series.
*** May be at least partly [[AuthorAppeal Creator Appeal]], on the part of animation director Atsuko Nakajima, who was so infamous for drawing her characters this way in the mid-90s that it earned her the nickname "Knockerjima".
* The sheer quantity of gainaxing found in the anime ''PlasticLittle'' inspired [[Creator/ADVFilms ADV]], the North American distributor/dub house, to include an on-screen "Jiggle Count" meter as one of the special features in their DVD release.
* The anime ''ShinkonGattaiGodannar'' takes Gainaxing to the extreme, since even the mecha have breasts (and in one particular case, ''both'' the mecha and the pilot have humongous ''jiggling'' breasts). The only exception to this is Lou, the show's TokenMiniMoe.
* Taeko and a few others in ''Manga/AiYoriAoshi''.
* Practically every female role in ''DivergenceEve'' and its follow-up. It may be noted that outside of this and the {{fanservice}}y opener and closer, the series is remarkably serious in tone and tells its story in blissful.
* Caldina in ''MagicKnightRayearth''.
* Virtually any adult female in ''DevilHunterYohko''
* The opening credits of ''{{Landlock}}''.
* The title character in Amazing Nurse Nanako falls prey to this, making an otherwise well plotted series difficult to watch "[[http://www.animepalm.com/series-images/amazing-nurse-nanako.jpg]]"
* While not exactly as flagrant, Murrue Ramius of ''[[Anime/MobileSuitGundamSeed Gundam SEED]]'' has the dubious honor of having her bouncing chest be one of the few whose bouncing was actually animated and used as StockFootage every time the ''Archangel'' took a particularly nasty hit in battle. This seemed to be limited to her, until first officer Natarle Badguirel ended up in command of her own ship, whereupon she gained the suddenly bouncing breasts (albeit not as dramatically given her modest proportions), as did Flay Alster as part of her crew. Whether this is actually an accurate depiction of how breasts move in zero gravity is debatable.
** Murrue was also the first woman in the ''Franchise/{{Gundam}}'' franchise to have her jiggle ''in the opening credits of the actual series itself''. She was replaced in the HD Remaster by Fllay Alster. The [[Film/JamesBond James Bond opening credits level]] nudity is also bra-less and even had male viewers often going "...those don't work that way." Female tropers, on the other hand, winced in pain and often skipped those credits.
** "They wounded the burst-proof battleship in order to sway the heart of the captain." - ''{{Moetan}} II, volume 1'' (the book). Obviously, the word "heart" in the Japanese translation can also mean "breasts".
** Fllay also displayed quite a big of bounce in the flashbacks to [[http://fyeahkirafure.tumblr.com/post/14205211922 the sex scene with Kira]]
** Parodied in GundamBuildFighters episode 17. A DirtyOldMan really likes Ramius' bounce.
* Yoko, and Kittan's three sisters (who come in small, medium and large for your viewing pleasure) in ''Anime/TengenToppaGurrenLagann''. Guess who it's made by. In fact, [[http://www.youtube.com/watch?v=FXhU3H8KPZk the English trailer]] for Gurren Lagann contained the words "that famous Gainax bounce". Yoko is an especially amusing example because her breasts seem to ''spontaneously'' Gainax without any movement on her part, whenever any attention is called to them.
* Mikuru Asahina, the {{Moe}} character in ''[[SuzumiyaHaruhi The Melancholy Of Haruhi Suzumiya]]'', displays Gainaxing, particularly in the opening credits.
-->'''Kyon''': ''[[CrowningMomentOfFunny Too many beach balls]]!''
** Also very evident in [[http://www.youtube.com/watch?v=c5G5bD2Do-k the ending credits]], especially at 0:13-0:16 (she's on the right).
** It's even {{Lampshaded}} in a Season 2 dub [[HilariousOuttakes outtake]]: "Look at these things, they move ''independently'' of each other!"
* Rushuna Tendo, every episode of ''{{Grenadier}}''. However, as she [[VictoriasSecretCompartment keeps her ammo in her cleavage]], this is actually somewhat practical. The BigBad Setsuna, being similarly well-endowed and trained, does the same thing.
** And for extra Gainaxing, she uses her bounce to execute an UnorthodoxReload, which always gets plenty of MaleGaze.
* The [[FanVid AMV]] "[[http://www.animemusicvideos.org/members/members_videoinfo.php?v=7660 The Fanservice Video: Bouncing Back For More]]" by Zarxrax is dedicated to this effect.
* Almost every female character in the anime ''Manga/GirlsBravo''.
* Naga the White Serpent, from ''LightNovel/{{Slayers}}''.
** It almost got her killed once, her rack sprang back into shape after being pressed against a wall, nearly launching her over a cliff.
* Angela, an American visitor to ''{{Genshiken}}'', displays this conspicuously (complete with bouncing sound effects) to make the differences between Japan and America (or at least {{Eagleland}}) more obvious, and to highlight her more upfront attitudes about sex (she is an unashamed YaoiFangirl) and maybe a bisexual (she was at least interested in the male oriented hentai as well).
** Oono also gets this quite often.
* A certain animation team in the rotation for ''Anime/DigimonSavers'' used this technique on Rosemon, and it's probably not a coincidence that they animated [=BioLotusmon=]'s only appearance.
** It's worth noting that before ''Savers'', the only minor use of this trope was in the second ''Tamers'' movie -- Sakuyamon's bounce a bit when she's freed from a Parasimon tentacle.
* ''Anime/DigimonXrosWars'' has Lilithmon and her boobs (she even fondles with them), and then there's Mervamon for the good guys (the opening even has her boobs bounce!), who even fires lasers from her breasts.
* Siesta from ''LightNovel/ZeroNoTsukaima'', pictured [[http://static.tvtropes.org/pmwiki/pub/images/cit_zero_no_tsukaima_2_behold_the_power_of_siesta.gif here]]. You're probably not looking at the LoveBubbles surrounding her.
** Not to mention Kirche the Ardent.
** Siesta is ''nothing'' compared to Tiffania, who barely has to ''move'' to set her breasts bouncing around like {{Flubber}}.
** Used to great hilarity in one episode when the gang is trapped in a cave. They hear something approaching fast and prepare for a fight, until Saito realizes exactly what that sound is with a priceless look on his face while the viewers get the obligatory chest shot of the approaching Siesta (who's wearing the Sailor Fuku outfit Saito bought earlier).
* Mai from ''Anime/{{Mai-HiME}}'' dresses conservatively, but her somewhat large (but not GagBoobs-level) chest still has a bit of bounce to it. A scene early in the anime replicated during an argument with Yuuichi and Shiho gives them an audible "boing". According to [[AllThereInTheManual supplemental materials]], it's not even Mai who has the largest bustline. She's beaten out ever-so-slightly by ''Haruka'', who ''doesn't'' have a whole lot of bounce, but still looks good in a [[BeachEpisode swimsuit]].
** Strangely enough, while attention is frequently called to her [[{{Pettanko}} lack of a chest]] in the [[Anime/MaiOtome original series]], Arika in ''Anime/MaiOtomeZwei'' starts bouncing quite noticeably, especially whenever she prepares to use her signature move. One could argue, though, that she has filled out in the one year since the end of the series.
* ''MacrossFrontier'' features a whole raft of characters with sufficiently Gainaxed breasts, including Sheryl and the Miss Macross Frontier contestants (which makes [[ACupAngst Ranka]] uncomfortable.) Also, ''zero gravity bouncing''. Very unique.
** Interestingly the show also subverts the trope slightly: when a fully sized, thirty-foot-tall Zentraedi, Klan Klein has a rather terrifying bust that may actually be capable of ''killing'' a normal-sized human. Micronized, however, she doesn't possess anything that can ''be'' Gainaxed.
* ''[[Anime/ReadOrDie R.O.D. TV]]'' had one particularly infamous chase sequence where Nenene finally finds her long lost friend ([[LesYay love?]]) Yomiko Readman. Yomiko runs away and Nenene gives chase. As they sprint, their bosoms (which had been largely still until then) bounce and sway like jello earthquakes. It's also worth noting that Yomiko's bustline went from a mild C-Cup in the OVA well into DD territory for the TV series, set several years later. A late blooming?
** It isn't just the chase scene. Watch Nenene's bosom in the first episode. They ripple like water.
* This happens to Milly and Shirley during one of the SchoolFestival activity episodes in ''Anime/CodeGeass'' and to Kallen, the most noticeable example being her encounter with Suzaku on Kamine Island. You'd think that Kallen, having one of the larger chests of the female characters featured on the show as well as being the most physical girl, would get ''a lot'' more of this during the action sequences but the total count reaches no more than a handful.
** Well, [[WeirdScience any more than a handful is a waste.]]
* After the TimeSkip in ''MagicalGirlLyricalNanoha'', Nanoha and Fate, no longer young girls, displayed this trope during their TransformationSequence, as did Subaru.
** Before the TimeSkip, Arf displayed this trope whenever she got a chance to.
** Fate got it from Precia.
** If the video game is any indication, then Vivio's quite bouncy in her adult form as well.
** Shockingly, despite having one of the larger bust sizes in the series, Signum doesn't bounce very often. She apparently prefers to show some leg.
* Surprisingly, several girls in the ''{{Saiyuki}}'' anime jiggle around in action, even though the show is mostly fangirl fodder.
** Then again, ''Saiyuki'' was originally marketed as {{Shonen}}.
* Done poorly with Bekira in ''WagayaNoOinarisama''. Kind of {{lampshaded}} by Noboru taking a quick glance at Kou's assets for comparison. Subverted later on when it turns out those weren't actually her breasts.
* Parodied and [[LampshadeHanging lampshaded]] in an anime-original RPGEpisode of ''Manga/HayateTheCombatButler'' where the bouncing boobs of the RPG game's boss is focused on constantly and has a sound so audible a character points out that she hears the sound of the bouncing from a considerable distance away.
* In ''VisualNovel/AkaneIroNiSomaruSaka'''s eighth episode, whenever the camera focuses on Tsukasa, her breasts appear to take on a life of their own. The first scene, which is just a profile shot of her laughing, has them bouncing up and down like crazy.
* In one episode of ''Manga/{{Naruto}}'', the seriousness of Gaara transforming [[{{Narm}} is lost]] thanks to Temari's inexplicable Gainaxing, which is something that no character in the show had really shown before or since (even Tsunade, who despite having a bustline greater than a meter, no bra, and a very active combat style, has her breasts remain perfectly stable).
** It appears as though you haven't seen 106cm [[http://www.youtube.com/watch?v=ny7Fni193Jk]] (bad quality)
** Now Samui from the Cloud village has it
* Margery Daw in ''ShakuganNoShana'''s FestivalEpisode.
* Junko Asagiri from ''Manga/DesertPunk'', during the end credits.
** [[GagBoobs And, you know, everywhere else.]]
* Rosette does this in the third episode of ''ChronoCrusade'' -- unfortunately bad animation makes it look as if she had bags filled with water instead of breasts.
* Done with refreshing realism in ''GargoyleOfTheYoshinagas''. A character's breasts do bounce but only after another character steals her bra.
* Yurika in ''LightNovel/{{Akikan}}'' actually uses Gainaxing as a strategy. In a baseball game with Yell (who's [[AttentionDeficitOohShiny distracted by moving objects]]), she apparently plays without a bra on purpose, leading to very springy bouncing that Yell just can't take her eyes off of.
* Izumi in ''KemekoDeluxe'', all the time.
* Studio Gainax is responsible for animating the ''Re: CutieHoney'' {{OVA}}s. Hoo boy, is there ''ever'' {{Gainaxing}} in that show.
* ''NininGaShinobuden'' gives Shinobu a few good bounces in episode 4. Then again, the first half of the episode is a spoof of FanService anyway.
** The baseball episode has a ninja distracting himself by imagining Kaede in a tiny bikini, complete with bouncing. The ''real'' Kaede bowls him over because he's not paying attention.
* Parodied in ''SamuraiChamploo'' when small-chested Fuu decides to carry a couple of cherry bombs by [[VictoriasSecretCompartment sticking them down the front of her kimono.]] And then she goes for a run. The result is quite comical, which is compounded by the occasional viewer who didn't notice the cherry bomb thing and thinks that her breasts have just gone insane.
* The appropriately-named Bouncy Tiff, who is created to the real Tiff's dismay. She is drawn like a stereotypical magical girl and... err, deserves the "bouncy" portion of her name. Even the youngest character in the crew knows to cover his eyes. The anime she appears in? ''KirbyOfTheStars''.
* Miyuki in ''{{Basquash}}'', who has her bouncing breasts take up the entire screen for a good few seconds.
** Which is taken to the next level with Haruka Gracia, who we get to see jiggle on three separate occasions before actually seeing her face.
* Check the BeachEpisode of ''Anime/PleaseTeacher''.
* In the ''MakaiSenkiDisgaea'' anime, we have Jennifer, the female assistant of Captain Gordon, '''Defender of Earth!'''. The sight of her chest bouncing is enough to make Laharl sick.
* Team coach Momoe from ''OokikuFurikabutte''.
* ''VisualNovel/GreenGreen'', to a truly ''ridiculous'' extent.
* In the same vein as Mikuru and ''SuzumiyaHaruhi'' above, Kyou Fujibayashi of ''VisualNovel/{{Clannad}}'' Gainaxes like mad in the opening credits of the first season, ''while bouncing a basketball''.
** Kotomi also does so in the BaseballEpisode.
* Also on the same vein, [[OtakuSurrogate Patricia Martin]] displays it during while cheerleading in {{Lucky Star}}'s opening DancingTheme.
* The ''{{Shuffle}}'' OVA had Sia and Asa Gainax within the first three minutes. Then when Sia's dad replaces the water in the pool with eels, Nerine does as well.
* The anime of ''VisualNovel/UminekoNoNakuKoroNi'' gave most of the women and girls a bad tendency to do this, which would be fine if this were a comedy series. Unfortunately, Umineko [[KillEmAll is]] [[MindScrew not]] [[ParanoiaFuel a]] [[PsychologicalHorror comedy series]]. Poor Shannon has the worst of it. Every time she makes a sudden movement or reacts to something, her boobs also react, with a single bounce.
* In ''Manga/{{Bleach}}'', Rangiku's breasts bounce when she is frightened by Capt. Hitsugaya's intrusion. She even says that they almost popped out of her robe.
** When Orihime was about to change (in front of Uryu, [[InnocentFanserviceGirl uncaringly]]), her breasts just flopped down from her shirt. In the video games, she demonstrates this as well.
** [[ElegantGothicLolita Cirucci]] [[EvilIsSexy Thunderwitch]] has a blink-and-you-missed-it one in an {{omake}}.
* Even one of the more serene shows, ''Anime/UmiMonogatari'', gets a chance to indulge in this trope. Oshima, Kanon's rival, is flaunting her own bust size, when [[MessianicArchetype Marin]] comes running up to greet her. Marin, already halfway to being an InnocentFanserviceGirl, is not wearing a bra. The results leave Oshima stunned.
* [[GagBoobs Nodoka]] of ''Manga/{{Saki}}'' says hi. Just the simple act of walking could get her breasts jiggling.
** A critic from Website/AnimeNewsNetwork once noticed that her entire wardrobe is sewn in just the right way for her shirts to perfectly cup her chest.
* This happens in episode 19 of ''[[Manga/FullmetalAlchemist Fullmetal Alchemist: Brotherhood]]''; for unexplainable reasons beyond pointing out that Havoc likes big boobs, Lust's boobs bounce considerably.
* Mii in ''JungleDeIkou'' Gainaxes quite a bit, thanks in part to her huge rack (Mii's breasts are supposed to represent Earth's life-giving energy); this is taken to a somewhat absurd level when Mii uses her powers to turn into a giant.
* ''HighSchoolOfTheDead'' combines {{Gainaxing}} with BulletTime. [[http://www.youtube.com/watch?v=10x6aMvspis ''And it is ridiculously awesome!'']]
** According to [[http://www.reddit.com/r/anime/comments/ngelc/speed_of_sound_15_speed_of_boobs/ uncredited analysis]], the speed of the breasts in that shot [[http://i.imgur.com/etyLu.jpg exceeds 1800m/s]]!
* Another Studio Gainax creation, ''Anime/NeonGenesisEvangelion'', would always promise "more fanservice" in the next episode. Strangely, this was the one time Studio Gainax ''didn't'' follow this trope: the show did have a fair amount of tongue-in-cheek fanservice, but its overall animation style was less "cartoony" and trying to be photo-realistic, so unrealistic "breasts bouncing around like water balloons" didn't really happen that often.
* Studio Gainax made up for the lack of excessively mobile breasts in ''RebuildOfEvangelion''.
** Mari puts on her new plugsuit and comments how comfortable it is, demonstrating how well it can support her relatively huge chest. It was relatively realistic, tough. And she was wearing skin-tight, elastic clothing at that time.
*** Also seen at two moments later in the movie, when destruction of the bones guarding an angel's core caused its chest to lose its tautness, resulting in a bounce of building-sized breasts; and when a naked Rei gasped in surprise.
*** In 3.0 a fairly serious scene becomes a little less so when it cuts to Mari's breasts bouncing excessively from the impact of her Eva's running footsteps.
* In an odd variant, ''BraveCommandDagwon'' has this happen to Galaxy Luna's buttocks during her henshin sequence. ([[http://www.youtube.com/watch?v=u4Ajh989z0M&NR=1 Said sequence starts at 1:07]]).
* When Ukraine from ''AxisPowersHetalia'' was featured in episode 42 of the webcast, her GagBoobs received, well, ''[[MaleGaze quite]]'' [[MaleGaze the attention]]. And her shirt's front button popped out ([[CallBack followed by a later scene where she tries to sew the button back in place]]). ''And'' her boobs make an audible bouncing noise when she moves (which Latvia refers to as "booby bounce" in the English dub).
** [[http://community.livejournal.com/largetracts There's even a ([=NSFW=], obviously) community dedicated entirely to her breasts.]]
** [[http://www.facebook.com/search/?q=ukraine#/group.php?v=info&ref=search&gid=171711217885 And another!]]
* Done in the manga of ''MahouSenseiNegima'' through use of a sound effect. The sound of a bouncing breast is, strangely, [[spoiler:bwabitib]].
* Bouquet in the ''[[TheAnimeOfTheGame Blue Dragon]]'' series. Combined with MsFanservice, as her powers only activate when she's naked.
* [[HighlyVisibleNinja Kasuga]] from VideoGame/SengokuBasara series (anime) not only gets bigger boobs than in the game, but they visibly bounce around when she moves quickly. Seeing her status as MsFanservice, it's not surprising.
* ''GhostInTheShellStandaloneComplex''. The first view we have of the HospitalHottie who has come to give Major Kusanagi a new cyborg body is her bouncing breasts. The fanservice is increased tenfold when she starts making LesYay comments while [[CreepyPhysical examining]] the BiTheWay Major. [[spoiler:Subverted in that she turns out to be [[SickbedSlaying an enemy planning to kill her]].]]
** Notably averted with the Major herself, however, whose admittedly generous breasts are artificial, like the rest of her body, and actually animated that way.
* ''VisualNovel/HigurashiNoNakuKoroNi'' had this happening to Mion [[spoiler:(really Shion)]]. Like every other {{fanservice}} trope used, [[FanDisservice it came off as seriously creepy]].
* LadiesVersusButlers is full of this, having ample fanservice moments. Sernia Iori Flameheart in particular, she even gets the sound effects, generally the other girls don't.
* GoldenBoy did this quite a bit, especially in the first episode (from the owner of a computer software company).
* QueensBlade has this by the truckloads but episode nine of the first season is most appropriate example being a Cattleya centric episode
* Manga/{{Airmaster}} Mina has plenty of this but she's a Subversion of MsFanservice and her [[GagBoobs figure]] is played mostly for laughs as her breasts tend to bounce out of sync with the rest of her body and the movements are extremely exaggerated
* Chu's entire entourage in ''Manga/{{Mouse}}'', even the flat chested one.
* Done hilariously in the BeachEpisode of ''[[TokimekiMemorial Tokimeki Memorial Only Love]]'' with swimming team captain Koayu Utsumi, whose GagBoobs jiggle just from her merely looking around, complete with sound effects (and it doesn't help that it's getting all the attention of all the guys around, which she hates so much, and especially since she's on lifeguard duty at the time).
* Happens at one time or another to most of the female cast of the anime releases of the KoihimeMusou franchise who have large breasts, especially to Kannu. Ryuubi even gets to do it on purpose later in the series to [[DistractedByTheSexy lure someone into a trap]].
* The entire point of TrainingWithHinako.
* Haruhara Haruko in ''{{FLCL}}''. It is Gainax after all. Of particular note is the random bunny suit she wears during the big battle in episode 5.
* The eponymous Rio from ''RioRainbowGate'' has very bouncy assets, which get ample emphasis in the show. The fact that she dresses in an extremely revealing manner for a casino croupier, [[BareYourMidriff baring her midriff]] and [[DangerouslyShortSkirt wearing an ultra-short skirt]], only exacerbates this.
* PlayedForLaughs in SeitokaiYakuindomo with Aria Ichijou. Being MsFanservice, her boobs jiggle on occasion, often to emphasize how [[ACupAngst jealous the other girls are of her size]]. At one poimt, she ''willed them to bounce on their own'' when the discussion turned to them.
* PlayedForLaughs in the animated ''omake'' of Manga/BlackLagoon, when Rock wakes up [[GenderFlip as a woman]]... [[http://www.youtube.com/watch?v=BoSMtWykUq8 "WITH HUGE BOOBS!"]].
** In the series proper, Revy's very acrobatic GunFu causes this to occur during her fight scenes. More noticeable in some than others.
* ''MaicchinguMachikoSensei'' was perhaps the first anime to do this, although the gainaxing in that show is tame by today's standards.
* Happens a bit in the ''Manga/FairyTail'' anime with the various girls, most notably [[spoiler: [[ShesAllGrownUp Edolas!Wendy]]]].
* Seraphim often from ''KoreWaZombieDesuKa''
* [[ZigZaggingTrope Zigzagged]] between Takane and Azusa in the anime version of ''[[Anime/TheIdolmaster THE iDOLM@STER]]''
* In chapter 117 of ''Manga/BlackCat'', one panel has Saya Minatsuki dodging Creed's slashes, causing her breasts to swing in visibly different directions. She's far from the bounciest female in the series, but she does seem like the kind of girl that would go without a bra in the comfort of her own home (which is where she was when that asshole Creed barged in on her).
* ''VisualNovel/MajiDeWatashiNiKoiShinasai'' has Momoyo, whose BoobsOfSteel defy gravity.
* [[MsFanservice Kurokami Medaka]] has this ''all the time'' in the AnimatedAdaptation of ''MedakaBox''. Complete with the bouncy sound effect. Well, it ''is'' a StudioGainax anime...
* {{Sekirei}} is a WorldOfBuxom HaremGenre anime/manga that has the tagline ''Boobies for the win!'' and the nickname "''Franchise/{{Pokemon}}'' with tits". You do the math.
* Occurs frequently in the anime adaptation of ''LightNovel/IchibanUshiroNoDaiMaou''.
* Yuriko deliberately does this to Daichi while on the train in episode 6 of ''Manga/KotouraSan''. He {{ignore|TheFanservice}}s it, much to her frustration.
* In the anime of ''LightNovel/TheAmbitionOfOdaNobuna'' Katsuie has quite a bit of bounce to her breasts. Even wearing a ''solid steel breastplate'' doesn't stop her gainaxing.
** Louise Fróis also displays this.
* ''Manga/SakuraTrick'' does that on Haruka's self-declared D-cups. Kotone sometimes has this treatment.
* Played for FanDisservice in ''{{Berserk}}'' with Casca, as the only time we see this happen is [[spoiler: during her rape by Femto, where the gainaxing actually serves to show how violently she's being assaulted.]]
* ''Anime/KillLaKill'' has this with Ryuko and Satsuki, ''especially'' during their transformation sequences.
[[/folder]]

[[folder:Eastern Animation]]
* Animation/AachiAndSsipak has a female character that does this throughout the movie to hilarious effect. At one point, she somehow manages to find herself strapped to a motorcycle, riding on her rack, while bouncing down some stairs.
[[/folder]]

[[folder:Film]]
* A truly groan-worthy live action example in ''[[Film/{{Transformers}} Transformers: Revenge of the Fallen]]'', in which Mikaela (played by MeganFox) bounces like Pamela Anderson on ''{{Baywatch}}'' in Creator/MichaelBay slow-motion in what is supposed to be a dead-serious escape sequence. However, given that the ''entire sequence'' is in slow motion, she is running for her life, and they only had ''one'' take, it's somewhat more understandable.
* A rather disturbing one is present in ''WesternAnimation/DespicableMe'', near the start. as [[spoiler: the fake pyramid deflates, the escaping air]] causes an old woman's saggy...[[BrainBleach well, you get the picture]].
* The Z-grade film ''Hollywood Hot Tubs'' had Crystal, whose entire reason for existence was jogging braless in every scene, even jogging in place [[DepartmentOfRedundancyDepartment when standing still]].
* A similar film, ''Bikini Summer'', showed an extreme close-up of jiggling before the opening credits even began rolling.
* ''BlackMamaWhiteMama,'' every time Pam Grier (or many of the other nameless women) run.
* One of the ''Film/LaraCroftTombRaider'' movies had a particularly glaring example even for them, where Lara runs (in slow motion of course) at full pelt resulting in a lot of movement that looked like it would be quite painful really.
** That would be the first one. It looks like it ought to violate the laws of physics and biology, probably a result of the decision to enhance Angelina Jolie's breasts.
** WordOfGod states that the only part of Angelina Jolie that actually had any padding at all while filming was her breasts.
* In the Creator/UweBoll film ''Film/HouseOfTheDead'', Ona Grauer becomes outright pneumatic during a [[OutrunTheFireball slow motion run during an explosion]]. Like Jell-O on springs, indeed.
* There are a couple of noteworthy sex scenes in ''CabinFever'' prominently featuring CerinaVincent's breasts. But in particular, the second one involves a [[ToplessnessFromTheBack behind-the-back shot]] in which we can see an intense jiggle as she forcefully rides her lover du jour.
* In ''[[{{Zorro}} The Legend of Zorro]],'' there's a scene where Catherine Zeta-Jones runs away from dogs in a low-cut dress. It's probably not intentional, given the shortness of the scene.
* In the Adam Sandler movie ''Film/{{Click}}'', one of the uses Sandler's character finds for [[RewritingReality a remote control that works on the real world]] is to use the "slow" function on a buxom jogger.
* Becky (Creator/RosarioDawson) dancing on the roof of Mooby's in ''Film/ClerksII''. There's a less, uh, ''restrained'' example of her in ''Film/{{Alexander}}''.
* ''WesternAnimation/{{Animalympics}}'': one of Brenda Springer's scenes really could've ended slightly earlier than it did, but the animators apparently felt the shot wouldn't feel complete until all the jiggling stopped.
* Another particularly cringe-inducing example is when Caramon first realizes that Tika is a beautiful woman in the [[SarcasmMode amazingly wonderful]] ''{{Dragonlance}}'' [[AnimatedAdaptation film]].
* There's a bit of Gainaxing in the [[Film/SpeedRacer live-action Speed Racer movie]]. Take a look at Trixie (Christina Ricci) when she runs into the room during the [[InstantAwesomeJustAddNinja ninja fight scene]].
* Parodied in the LeslieNielsen film ''WrongfullyAccused'' -- while the female lifeguards are running in slow motion, their breasts make comically audible bouncing sounds.
* ''{{Airplane}}'' has a shot where we have a closeup on a wobbling jello plate while the plane is in turbulence, and then pans over to... well, [[SarcasmMode just guess.]]
** Also, the scene where the passengers panic after the line "Does anyone know how to fly a plane?" has a topless woman appearing out of nowhere, jumping around close to the camera.
* ''GIJoeTheRiseOfCobra'' has a scene where the team is exercising in their gym, and Scarlett (Rachel Nichols) just happens to be jogging on a treadmill.
* Both Miss Scarlett and Yvette do this in ''Film/{{Clue}}'', though moreso Yvette, due to [[FrenchMaid choice of attire.]]
* ''Franchise/StarWars ANewHope'', of all places. Suffice to say, they eventually had to tape down Carrie Fisher.
* ElizaDushku has had this in many of her roles, but special mention must go to her first [[FanService topless scene]] in ''Film/TheAlphabetKiller''.
* ''Epic Movie'' does this with three different jogging people:
** The first one is a scantily-clad woman.
** The second one is a shirtless man whose GagPenis bounces.
** And in a moment of FanDisservice, the third one is a fat hairy shirtless man with bouncing man-boobs.
* Creator/ScarlettJohansson in her opening fight scene in ''Film/TheAvengers''. Justified in that she's wearing a black cocktail dress which is ''not'' intended for the gymnastic martial arts moves she's using. Her Black Widow SpyCatsuit keeps her more... restrained.
* Probably the most horrifying instance of this is in the 2000 sequel to the Eddie Murphy remake of TheNuttyProfessor, with Granny Klump.
* In ''Film/MontyPythonsTheMeaningOfLife'', Arthur Jarrett is allowed to choose the manner in which he is executed. He chooses to be chased off a sea cliff by ten voluptuos women who are wearing sneakers, knee-pads, bikini bottoms and helmets. ''Cue slow motion chase scene'' Made even more funny because Arthur is played by Graham Chapman, who was gay.
* Linda Blair has a scene like this in ''Film/TheExorcist'' Part II, ''The Heretic''. She's tap-dancing (badly) in a school recital in a very low-cut costume. All anyone remembers from that scene is the fact that she badly needs a bra.
* We have Emma Frost's slow-motion bouncing near the end of ''Film/XMenOriginsWolverine'' before the helicopter.
* Trixie does this in Speed Racer during the "Non-ja" scene. Hey, it is a live action anime.

* LoisMcMasterBujold's ''[[Literature/VorkosiganSaga Diplomatic Immunity]]'' mentions the 'charming effect' zero-G has on the female form.
* In ArthurCClarke's ''RendezvousWithRama'', Commander Norton notes how distracting women can be in zero-gravity, particularly if "sympathetic vibrations" occur.
* There is an interesting description of this happening to Big Boobied-Bertha in one of the ''Literature/HowToTrainYourDragon'' books.

[[folder:Live Action TV]]
* ''Series/HappyEndings'' has a classic example in 'Secrets and Limos', Dave's GirlofTheWeek comes into Jane's house, takes her coat off and just does a little shimmy to get out of it, setting her mams a wobble. It is clearly noticed by both Brad and Jane
* ''Series/AlloAllo'' -- let's just say "vibrating ice cream truck".
* Elaine on ''AllyMcBeal'' invented a vibrating bra that would make the wearer's breasts twirl in circles.
* ''Series/TheBill'' -- a couple of incidents described as "Bouncy Bouncy Jo Masters".
* BBC Garden-show hostess Charlie Dimmock received a certain degree of fame for her tendency to go braless and jiggle.
** So, forty years ago, did ''children's TV'' host Susan Stranks. FetishFuel for the under-fifteen set, anybody?
* This video. So much bouncing, and no shirt! NSFW. http://www.youtube.com/watch?v=wTs96p88pcc&feature=channel
** [[spoiler:Bastard. For the record, it's a gentleman, possibly a sumo wrestler, who bounces and jiggles.]]
** There is also [[spoiler:a female (clothed) version]] [[http://www.youtube.com/watch?v=QfF695eO0oY&feature=relmfu here]] from the same show.
* ''{{Baywatch}}.'' Kind of a given, what with the cast containing so many gorgeous women in form-fitting swimsuits.
** This is the reason why Chandler and Joey from ''Series/{{Friends}}'' love the show. In "The One Where Eddie Moves In":
-->'''Joey:''' Hey, hey, they're running!
-->'''Chandler:''' See, this is the brilliance of the show. I say always keep them running. All the time, running. Run! Run Yasmine, run like the wind!
* PlayedForLaughs in memorable and very intended scene in the second paintball episode of ''Series/{{Community}}'', which shows Annie running in slow motion with a rather noticeable cleavage.
** Earlier in the same season, Troy and Abed are DistractedByTheSexy due to Annie's Gainaxing…while she's yelling at them about being treated as a sex object.
* Long before Pam Anderson hit the beach, Lynda Carter perfected the art of running in slow-motion in a bustier in the 70s ''Series/WonderWoman'' TV series. There is a reason why some say "the ''Baywatch'' run" was invented by this series. [[http://www.youtube.com/watch?v=QSR6isVJaEA Observe]]
* ''ThePriceIsRight.'' [[http://www.youtube.com/watch?v=noggIParXOA&NR=1 Now in slow-motion compilation form]]!
* Elliot from ''Series/{{Scrubs}}'' is pretty much the show's MsFanservice, and it often happens because she can be neurotic and excitable. A particularly notable one is when they are in a bar with J.D. and Turk playing a game, Elliot wants to play along too, saying [[http://www.youtube.com/watch?v=CtEVy_zjr9Y "Oh... Do me! Do me!" while jumping up and down]].
** Also after her makeover in "My All American Girl", walking down the hallway... bounce... bounce...
* Kelly Bundy from ''MarriedWithChildren'' often did this whenever she got excited.
** Actually, most of the women (who weren't flat-chested like Marcy or fat like the many customers in Al's shoe store) on ''MarriedWithChildren'' gainaxed, from Peggy Bundy to the many [[SatelliteLoveInterest shallow love interests]] Bud tried to score with.
* ''MyNameIsEarl'' had Catalina's stripper act entirely just jumping up and down. Another episode featured a claymation Joy whose breasts moved independently of each other, much to Randy's fascination.
* This also often happened to Chrissy Snow from ''ThreesCompany'' whenever ''she'' got excited, resulting in the coinage of the term "JiggleShow".
* ''Series/GhostWhisperer'' has taken numerous opportunities to have Jennifer Love Hewitt run in something low-cut. In fact she seems to find a way to introduce some jiggle to every project she's in, including the bra ads.
* Rachel Luttrell as Tayla Emmagan in Stargate Atlantis used to be known for this. Even in fight scenes. Especially in fight scenes! One director had her stop swinging a staff and * pose* in order to display her impressive chest to best effect.
* Nissan car commercial [[http://www.youtube.com/watch?v=zKO-tZGuFDg&feature=fvw]]
* On one episode of ''DancingWithTheStars,'' contestant Kelly Monaco was arguing with her partner, Val. She was trying to tell him how much Gainaxing occurs (and how uncomfortable it is) when you're doing the very bouncy quickstep when you actually have a set of breasts. To prove her point, she bought a bra, put a water balloon in each cup, put it on Val, and forced him to do the dance again. [[http://www.youtube.com/watch?v=zqkgKlS3Lkg He got the picture.]]
* It is the life's work of the protagonists of the reality show DoubleDivas to avert this. They make sure that all their customers leave with well fitting bras.
* In ''Series/AgentsOfSHIELD'''s "The Asset," a low-cut dress-wearing Skye makes her escape from villains by leaping out of a window into a pool, swimming out and making a run for it. Cue the Gainaxing.

A check falls in my lap and... I'm a producer. I never knew it was that easy. All this time I've been trying to write scripts and characters and plots and stories that had meaning... “Will there be titty?’ ‘Sure.’ Boom, I'm a producer now.
-->‘Where have you been all your life boy, we've been looking for you in Hollywood. What’re these titties gonna do?’
-->‘Uh… jiggle?’
-->BOOM! Another check falls in my lap. ‘You’re a fuckin’ genius. Give him another check. I can’t write enough checks for you. You’ve answered our prayers in Hollywood. Jigglin’ titties! Who woulda thunk of it?’
[[/folder]]

[[folder:Video Games]]
* The Sorceress in ''VideoGame/DragonsCrown'' shows some painfully blatant jiggle.
* In ''NinjaGaiden Sigma 2'' for the PlayStation3, the Gainaxing of all female characters is controlled by the motion sensor in the controller. Lampshaded hilariously in the [[http://www.destructoid.com/ninja-gaiden-sigma-2-boob-jiggle-commercial-is-amazing-148833.phtml commercial]].
** Ditto ''Ninja Gaiden III: Razor's Edge'' on the WiiU, since the Wii U gamepad also has a motion sensor.
* In Vampire:TheMasquerade-Bloodlines many female Vampires, noticably Jeanette and VV have jiggle animations.
* ''BanjoTooie'' has Mrs. Boggy, an obese polar bear who jumps up and down for no discernable reason.
* Watch Morwen in ''VideoGame/TheLordOfTheRingsTheThirdAge'' when she starts to walk around in the cutscene after you rescue her. Somebody on the animation team was inconsistent.
* Rayne, the main character of the ''VideoGame/{{Bloodrayne}}'' series of games, and most of the other female characters in it, was notorious for it and noted by the media several times for its 'realistic' breast physics.
** Though Rayne's breasts are immobile while speaking except for the first half second of every line when they bounce exaggeratedly.
* Mai Shiranui from the ''FatalFury'' and ''KingOfFighters'' series. The ''FatalFury'' anime movie, in particular, was infamous for the animators [[CensorSteam actually showing]] (very, very briefly) the inevitable wardrobe malfunctions her {{Gainaxing}} would cause in her [[{{Stripperiffic}} distinctive costume]] during fight scenes. Viz Video, who released ''FatalFury'' in the U.S., used to show her bouncing in the trailers while the narrator made enthusiastic reference to "dual-independent-suspension ninja girl Mai Shiranui". Although her design in the first few games was relatively more conservative, the anime (and the 2D JigglePhysics in the ''KingOfFighters'' videogames) resulted in her {{Flanderization}} into a walking incarnation of this trope. In fact, the latest incarnation of the ''King of Fighters'' takes this to SerialEscalation levels.
** Even in the NeoGeoPocket games where she appears her breasts jiggle!
* ''VideoGame/SoulCalibur III's'' shop girls, specifically what could be done by repeatedly hitting Triangle in their shops. Especially Valeria's.
** Giving Xiangua's style to a well endowed custom character in Soul Calibur IV will result in lots of bouncing
** Quite noticeable in Soul Caliber Legends, namely Ivy. Every movement made them bounce with really weird physics, including going in and out(...?)
** If any character is the ''VideoGame/SoulCalibur'' shining example of jiggle physics, it's definitely Taki.
* Rouge the Bat, from the ''VideoGame/SonicTheHedgehog'' series, although this has been toned down in newer games.
* ''VideoGame/DeadOrAlive [[XtremeKoolLetterz Xtreme]] Beach Volleyball.'' The breast movements were synchronous until ''Dead or Alive Xtreme 2'', when they consequently lost any resemblance to actual bosoms.
** The first game even gave the option of choosing between static, semi-normal, and downright comical JigglePhysics.
* ''Franchise/TombRaider'''s main character, Lara Croft, gets pretty jiggly.
** Especially in the sixth game in the series, ''[[VideoGame/TombRaiderAngelOfDarkness The Angel of Darkness]]''.
* Take a look at [[MsFanservice Isabela]] walking from the side in ''VideoGame/DragonAgeII''.
* ''VideoGame/CastlevaniaJudgement'' has [[TheVamp Carmilla's]] do this, and Sypha, even [[TheStoic Shanoa's]] a little bit, but she's more known for her SexyBacklessOutfit.
* ''VideoGame/SuperRobotWars'', despite being a video game where all the action is done by [[HumongousMecha Giant Robots]], has rather extensive bouncing in the anime-ish cut-in pictures. Very prevalent in the [[VideoGame/SuperRobotWarsAlpha Alpha series]], where you can expect any original female character to have {{Gainaxing}} bounce, unless her name is Ibis Douglas. This also gets carried over to the latter handheld ''SRW'' games, such as ''J'' and ''W''. (Un)fortunately, ''VideoGame/SuperRobotWarsOriginalGeneration'' somewhat mellowed or stopped this practice.
** Only for ''EndlessFrontier'' to bring it back in a grand fashion: 3 of the playable characters happily show off their bosom every time you perform their LimitBreak (two of them involving a mechanism specifically designed to remove the cloth covering their cleavage), and most female bosses are happy to do this as well.
*** Funnily enough, even Xiaomu, from [[CapcomVsWhatever Namco X Capcom]] has what little cleavage she has bounce. In fact, every female character with the exception of Suzuka and Kyon Feulion have bouncy breasts.
** It starts at Alpha 2 and Alpha 3 had the most extreme version of this (I'm looking at you Selena Recital). After that, the bounce is a bit more in line with realism. By Z, the bounce is fairly tame and looks fairly natural (which is impressive given Xine's impressive rack).
** In fact, there's a fan-made montage of these cutins in ''VideoGame/{{Super Robot Wars Z}}2: Saisei-Hen'', set to [[http://www.youtube.com/watch?v=SWHAeBODHec DYNAMITE EXPLOSION]]
* ''VideoGame/TalesOfSymphonia'' played with this with the well-endowed (but not shockingly so) female ninja Sheena. However, it's only most noticeable when using her as the party avatar walking around, and it's hard to spot normally (there are a couple of places where you can get a closer look and have her run in place). It's also present in the animated ending cutscreen on [[spoiler:Martel]], the credits credit Gainax themselves for said animation.
* Queen Valentina from the original ''VideoGame/SuperMarioRPG'' had a conspicuously long after-hit animation that consisted solely of her flinching and jiggling for a few seconds.
** It's notable that the jiggling part lasts about 3 times longer than the flinch.
** Flurrie from ''VideoGame/PaperMarioTheThousandYearDoor'' has a ''sound effect'' that goes with her breasts bouncing.
* April May in ''PhoenixWrightAceAttorney'' shook her stuff when flirting or when she got extremely pissed off.
** And then there's the [[SoBadItsGood hilarious]] hentai game ''Phoenix Drive'', in which female characters' breasts spontaneously Gainax every few seconds, much as humans' eyes spontaneously blink.
* Jessica from ''VideoGame/DragonQuestVIII'', to the point where she distracts from the action taking place on screen whether you like it or not.
* Lucia and Sheena, the unlockable characters of ''{{Contra}} 4''. That is, if you look closely at their sprites.
* Lyn, from ''FireEmblem: The Blazing Sword'', [[http://www.feplanet.net/sprites-archive-battle-animations/l/2160/2158 every time she attacks]] while wielding her end game weapon.
* In ''MetalGearSolid4'', the player can induce this manually by jiggling the SIXAXIS controller during cutscenes.
* No mention of ''Metal Gear'''s PSP {{Spinoff}} ''Metal Gear Ac!d 2''? They even gave you ''3D goggles'' for it.
* The ''VideoGame/{{Tekken}}'' spinoff 'Death By Degrees'' has "breast physics" as its (only) selling point (along with ClothingDamage in boss fights).
* In ''VideoGame/SkiesOfArcadia'', Belle, one of the crew members you can recruit, is rather bouncy. Especially since she's also a GenkiGirl and source of much [[InnocentFanserviceGirl Innocent Fanservice]]. Did we mention you can end up talking to her while she's [[DoesThisRemindYouOfAnything polishing an artillery shell]]?
** For that matter, Bellena has some impressive (though subtle) jiggle physics.
** For a male example, you have Pinta's belly jiggles.
** The ''really'' interesting bit is that your two female companions (and a vast majority of other female characters, including [[spoiler: Piastol, an otherwise leather-clad dominatrix-looking type]]) do NOT have any jiggle physics to speak of. This implies that it isn't an artifact of the physics engine, but instead something that someone spent development time on simulating.
* Fiona from ''VideoGame/HauntingGround'' suffers this. Especially noticeable when you unlock some of her other very revealing outfits.
* Nearly every female character that isn't flat chested in ''Franchise/{{Disgaea}}''.
* Marjoly in RhapsodyAMusicalAdventure. It's especially noticable in her VillainSong, "[[http://www.youtube.com/watch?v=S04aVglDlOc Evil Queen]]".
* ''VideoGame/WorldOfWarcraft'' features Gainax physics in the ears of the elven races, though more prominently in the Night Elves than the Blood Elves. The Night Elf ears stick out to the side and are very large so the bounce is easy to see. The Blood Elf ears stand straight up and are smaller but bounce just as much.
** Their boobs move around quite a lot too. But actually, the boobs that bounce around a lot in VideoGame/WorldOfWarcraft are on female ''undead''. Sort of justified as they probably aren't attached properly anymore.
*** They even have a /silly that implies that they were [[FrankensteinsMonster originally attached]] ''to someone else''. ("Yes, they're real. They're not ''mine'', but they're real.")
*** Take a look at the female dwarf's running animation; it's almost hypnotic. But other then the Night Elves and Dwarfs, the jiggling is surprisingly realistic for a game.
* The ''Franchise/{{Pokemon}}'' Nidoqueen actually displays this in the Stadium games upon release and before executing a physical attack.
** Blue-Eyes of ''VideoGame/PokemonRanger: Guardian Signs'', despite being a tiny sprite, has visible Gainaxing when she does her ActionPose.
* The World in her win animation in ''VideoGame/MagicalDrop II''.
** In ''Magical Drop III'' (and to a lesser extent in the previous titles) nearly all of the female characters get this to some extent, but it's in nearly every animation for The World.
* This happens during the opening cutscene of ''VideoGame/NamcoXCapcom''. Really establishes the character being from ''SoulCalibur''.
** Speaking of CapcomVsWhatever, we had Rogue and Psylocke doing this when the Marvel crossovers really [[IncrediblyLamePun took off.]]
* Early ''VideoGame/GoldenSun DS'' gameplay footage shows at least one summon with gainaxing.
* ''VideoGame/BlazBlue'' has [[ChineseGirl Lit]][[HospitalHottie chi]] [[KickChick Faye]]-[[{{Meganekko}} Ling]]. The resident MsFanservice, Litchi has an [[GagBoobs extremely large pair of knockers]] that [[http://img109.imageshack.us/img109/6722/litchistand.gif bounce even when she's seemingly]] ''[[UpToEleven standing still]]''. There's a reason she's called "[[FanNickname Boobie Lady]]", you know.
** Also, fellow MsFanservice [[LittleBitBeastly Mak]][[GeniusDitz oto]] [[CuteBruiser Nan]][[HotBlooded aya]] [[http://e621.net/data/6e/4c/6e4cdf316090dfb13e60228e40feadfd.gif?1304049473 has this going on]], although to a [[IncrediblyLamePun lesser]] extent. As an added bonus, if her theme music is playing in the background, her boobs bounce to the rhythm!
* ''VideoGame/TalesOfVesperia'': Estelle wishes she could bounce like [[MsFanservice Judith]]. [[http://www.youtube.com/watch?v=ukZgaevRyqY&feature=related Especially in the PS3-version.]]
* Kongiku from ''MuramasaTheDemonBlade'' has very large breasts that tend to wobble and jiggle constantly, even when she's not doing much other than standing there, breathing. The jiggle isn't as exaggerated as the most extreme examples of this trope, but is quite noticeable.
* The priestess Rao in ''VideoGame/{{Okami}}'' jiggles wildly every time you meet her, [[spoiler:including after she's [[DemonicPossession possessed]] by the demon Ninetails]]. [[ChivalrousPervert Issun]] rarely refers to her as anything but "busty babe", even to her face.
** It's mentioned in the game's official art book that one of the programmers created a "bounce and sway program" with "great attention to detail" to get Rao's breasts to jiggle just right.
** Rao isn't the only one. There's the {{Stripperiffic}} wood sprite Sakuya, as well as the [[SeashellBra Draconian Dancers.]]
* Zola in ''BlueDragon''. She's by far the better endowed of the two girls in your party(and it shows). So naturally, instead of a bra, she wears a blue tube top. Tube tops are not known for their supportive properties.
* Female Selkies from ''FinalFantasyCrystalChronicles''.
* The female protagonist from EpicBattleFantasy's breasts can be clicked on and they jiggle [[spoiler: there's even an achievement for it]]
* Every single game from Japanese [[{{Eroge}} H-game]] maker Illusion. Being strictly h-games they generally have controls that affect the size, shape, firmness, effects of gravity....
** Surprisingly, somehow they seem to have averted (mostly) in their latest game which uses a different, much more realistic ([[UncannyValley for varying degrees of realistic]]) engine versus their traditional anime-esque style games. There is still bounce, but much less Gainaxey.
* In one cutscene in ''VideoGame/BatmanArkhamAsylum'', Batman tackles the newly {{Stripperiffic}} Harley Quinn by jumping on her through a pane of glass, causing her breasts to jiggle slightly.
* Evident on ''{{Primal}}'s'' {{Transformation Sequence}}s. Especially when Jenn turns into a Wraith, which causes her breasts bounce faster than normally.
* Dr. Naomi in ''NoMoreHeroes2DesperateStruggle'' has a preposterous bounce animation triggered when the player speaks to her in the laboratory. The self-awareness of this is heightened by Naomi's comment, 'Quit staring at me! I know what you're thinking-- and NO!' a nod to the fact that she appears to have ''grown'' since the first game in the series and been put in an impossibly small top. It is a simply wonderful piece of FanService.
** It's also found in the [[http://www.youtube.com/watch?v=gqaz1kDz14w intro]] to Pure White Lover Bizarre Jelly, a parody of {{Magical Girl}}s and {{Moe}}.
* MsFanservice Kasuga from ''VideoGame/SengokuBasara'' previously never displayed this despite sporting some impressive AbsoluteCleavage. However the latest game corrected this with subtle yet realistic bouncing, as did the anime series (where her breasts are much larger than normal and it was not all subtle).
* Being based on the Wrestling/{{WWE}}, it's a given with the licensed games. It does get hilarious in one of the older PS2 games, when you encounter them in cutscenes and their breasts jiggle noticeably every time they revert to their default position between dialog lines.
* In ''[[TokimekiMemorial Tokimeki Memorial Taisen Puzzle Dama]]'', Yuko Asahina has some animated sprites where her breasts bounce.
** And ''Tokimeki Memorial 4'' has Fumiko Yanagi's breasts bounce in her LimitBreak 's [[http://www.youtube.com/watch?v=GGAmeo0Y27E#t=0m54s portait animation]] during battles, as well as when she appears in the game's mini-OVA.
* All the female classes with even a sightly {{fanservice}}y outfit in ''RagnarokOnline'' have this. Is quite fascinating and disturbing to see the cutesy sprites' boobs bouncing when in idle battle mode.
* There's an animated ad on this wiki for a game apparently called ''Pristontale2'', consisting of your standard blue-skinned Amazon in a backwards corset [[{{Gainaxing}} breathing in, breathing out, breathing in, breathing out...]]
* [[{{Stripperiffic}} Echidna]] from ''TheBouncer''.
* [[VideoGame/FinalFantasyVII Tifa]] in ''[[DissidiaFinalFantasy Dissidia: Duodecim]]'' has this for her intro. She also calls out [[VideoGame/FinalFantasyIX Zidane]] for staring at them.
** Averted with Cloud of Darkness, since in {{Cutscene}}s she tends to glide slowly as she moves giving not enough momentum. But doesn't stop Laguna from staring regardless.
** It's also in a few of [=FF7=]'s cutscenes. Too bad it took until 10 for such [[JigglePhysics physics]] to be in effect even in battle...
* ''GodsEaterBurst'' has a small amount, but disturbingly, not for the human characters. Some female shape Aragami such as the Zygote, Sariel and Arda Nova Gainax quite a lot, most notably in Arda Nova's death closeup. Hell, [[http://images2.wikia.nocookie.net/__cb20100526032344/godeater/images/thumb/0/04/Amateras.jpg/531px-Amateras.jpg one monster]] has a rack that may very well be visible from space!
* Selvaria of ''VideoGame/ValkyriaChronicles''. Most of her major scenes focus either on her flaming blue badassity, or her.. um, "talents", and the jiggling is truly astounding when the camera's on them. One particularly dramatic scene suffers because of the focus on her breasts bouncing around in ''different directions''.
* ''VideoGame/AkatsukiBlitzkampf'' gives us Marilyn Sue, who's popular with fans both for her powerful, hard-hitting fighting style and for her huge, ''huge'' jugs that bounce and swing every which way as she smacks around her opponents.
* Princess Gwynevere from ''VideoGame/DarkSouls'' has some subtle {{Gainaxing}} with her tremendous GagBoobs.
* The female Boss from SaintsRowTheThird Can fit into this trope if you slide her sex appeal all the way to 100.
* Dahlia in ''VideoGame/DuelSaviorDestiny'' supposedly, though since her sprites are static we only have sound effects and Taiga's reactions to go on.
* As of installment #13.5, ''Hopeless Masquerade'', even {{Touhou}} has gotten in on the action. Although only one character actually bounces.
* {{Shantae}}'s boobs (and those of her female supporting cast) seem to get bouncier each time the graphics are updated. It's more realistic and less painful-looking than most other examples on the page, though.
* ''VideoGame/ResonanceOfFate'' gives us [[MsFanservice Countess Barbarella]], is seen only once in the game while eating. While she does so, her breasts bounce enough to make the laws of physics cry in a corner. [[HandsomeLech Vashyron]] has a hilarious internal monologue about her [[UnusualEuphenism bunker busters]].

* The female character in [[http://www.youtube.com/watch?v=QLN4Mh3VjwE this Final Fantasy parody.]]
* Every single female in Akumi has Gainaxing breasts, although said breasts are smaller than you'd expect.
* On ''WebAnimation/ShutUpCartoons'' we have a few examples:
** Oishi from ''Oishi Highschool Battle'' is gainaxing all the time. Oishi breasts are actually prehensile, on occasion the reach out and smack people, or fire laser beams from her nipples.
** A sequence in ''Samurai Daycare'' opening is a close-up of asymmetrical breast-jiggle.
* [[http://boobsdontworkthatway.tumblr.com/ Boobs Don't Work That Way]] is a Tumblr devoted to providing examples of this trope and brutally mocking them.
* Germaine in ''NeuroticallyYours'' fell into this trope once her breasts became massive after gaining weight. Her breasts jiggle as much as she ''blinks''!
* Miss Hannah Minx, in her videos, often wears ''very'' revealing clothing that causes her nearly head-sized breasts to jiggle even with the slightest movements such as waving an arm.
* ''WebOriginal/CollegeHumor'' makes ''[[FanDisservice vile]]'' use of this trope in it's Furry Force videos. [[https://www.youtube.com/watch?v=h1Dyqas6Sm8 Be warned, it's not for the faint of heart]].

[[folder:Webcomics]]
* Nauseatingly parodied in [[http://www.cad-comic.com/cad/20061025 this]] ''CtrlAltDel'' strip.
* One ''GaiaOnline'' comic update shows Lex, Sasha, and Ruby jogging in anticipation of an Olympics-themed event. About half the fan-edits of said comic focus more on Ruby's bouncing jubblies than anywhere else.
* Referenced in [[http://www.webcomicsnation.com/shaenongarrity/skinhorse/series.php?view=archive&chapter=46522#184692 this]] SkinHorse strip where a hacked game of VideoGame/MarioKart is described (but not shown, tragically) as having Peach not wearing a shirt and having a "Gainax bounce".
* Discussed as a superpower in [[http://bakedgoods.thecomicseries.com/comics/4 this]] ''BakedGoods'' comic.
* Sahira's breasts bounce around rather notably in this ''Webcomic/{{Spinnerette}}'' [[http://www.spinnyverse.com/2011/02/11/02112011/ comic]]. Curiously, characters with even larger breasts such as Greta Gravity hardly gainax at all. Then again, Greta Gravity ''is'' a GravityMaster...
* Inverted in ''WebComic/ScandinaviaAndTheWorld''. Sister America's large (fake) breasts don't move at all. Apparently they're "like footballs glued to her chest".

[[folder:Western Animation]]
* Jessica Rabbit from ''Film/WhoFramedRogerRabbit''. Her breasts were purposely drawn to bounce in the opposite rhythm of a normal female's chest while walking; she bounces down when a real person would bounce up, and vice versa.
** And they go "boing"!
* In the 1937 Disney short ''Mickey's Amateurs'', Clarabella Cow and Clara Cluck both have unusually large bust, ''jiggling to the rhythm of the music'' Clarabella plays on the piano.
* ''BettyBoop'' was also known to do this in certain cartoons.
* Hell, it's not even breasts, but ''InvaderZim'' got away with this through Zim's zit, aptly named "Pustulio".
** Technically it was necessary though, as the whole jiggling thing gave the hypnotic effect it had.
* ''WesternAnimation/TinyToonAdventures'' seemed to have a little fun animating a female anthro bear character called Julie Bruin ([[InkSuitActor based on, and voiced by]], comedienne and singer Julie Brown) this way in one episode. [[http://www.youtube.com/watch?v=xirDE57RlDA Here's proof.]]
** That episode was animated by TokyoMovieShinsha. Coincidence?
* In the third ''BoskoTheTalkInkKid'' cartoon "Congo Jazz", a ''[[NonMammalMammaries palmtree]]'' does this, with coconuts substituting for breasts.
* ''WesternAnimation/TeenTitans'' got away with doing this to Starfire from time to time.
* ''JusticeLeague'' did this on rare occasion. In the episode "Grudge Match", Roulette did this in the second scene. Figures, as she was promoting a CatFight ring.
** In "The Cat and the Canary" the animators should've been given a bonus for the part where Black Canary takes off her jacket before she spars with Green Arrow.
* And ''WesternAnimation/TheBackyardigans'' does it with Tyrone's '''ears''', particularly in [[http://www.youtube.com/watch?v=L-rPOcm6clk&feature=related season 1's opening (who cares if it's in Spanish? Just pay attention to the bouncing)]].
** The "Caveman's Best Friend" episode has Tyrone control the bouncing of his ears, even though it looked more like flapping during that episode.
* Several episodes of ''WesternAnimation/KingOfTheHill'' seem to have a rather excessive amount of closeups of Luanne's breasts while they jiggle.
* Victor's mum from ''WesternAnimation/CorpseBride'' is subject to this trope, although it's hardly your typical case seeing as how she's [[FanDisservice middle-aged and overweight.]]
* ''TrippingTheRift'''s resident MsFanservice Six was animated this way.
* Ralph Bakshi's ''WesternAnimation/FireAndIce'' features a very early (1983) pair of life-drawn (but hugely amplified) {{Gainaxing}} breasts on [[EverythingsBetterWithPrincesses Princess Teegra]].
* Shadowcat from ''WesternAnimation/{{Wolverine And The X-Men}}'' had her breasts bounce when she went after the CreepyChild in the "Battle Lines" episode.
* In ''Disney/TheLittleMermaid'' Ursula, of all characters, got an inordinate amount of time spent on her to make sure she jiggled realistically.
* Endive from ''{{Chowder}}'' was animated like this for a few moments in at least one episode. You could argue about the amount of [[{{fandisservice}} fanservice]], though.
** Truffles got the treatment once, as well as [[{{Squick}} Reubens]].
* Mrs. Beady from ''{{Barnyard}}'' and ''WesternAnimation/BackAtTheBarnyard'' has her boobs jiggle, even when she gets up from the chair.
* Princess Vespa in G4's animated ''Film/{{Spaceballs}}'' adaption is usually animated this way.
* The animated short film, ''LocoMelones'', shows two of the women's boobs bouncing.
* The buxom old lady from ''WesternAnimation/{{Coraline}}'' bounces quite a bit, particularly when she shoves her sister out of the way using her breasts. The FanDisservice levels are [[UpToEleven cranked up to eleven]] later on when she appears to be jumping on a diving board... [[{{Squick}} naked.]]
* Leshawna from ''WesternAnimation/TotalDramaIsland'' quite often, but it's very subtle.
** This has happened on occasion to Lindsay as well.
** RareMaleExample with Alejandro.
* Manuela from the ''LesLascars'' film is the embodiment of this trope. Even when she does the smallest movement like turning her head, her boobs move. [[http://img695.imageshack.us/img695/7053/1295543792448.gif Here's an example.]]
* Mixed with the video game type in the ''WesternAnimation/MegasXLR'' episode "Viva Las Megas." Goat is at a gaming convention. While discussing a new beach volleyball game with a guy, he says "[[JigglePhysics I hope they improve the secondary motion engine]]."
* [[http://simpsons.wikia.com/wiki/Titania Titania]], a bartender from ''WesternAnimation/TheSimpsons'' used this (combined with her natural talents) to her advantage in order to try and win the "Beer-Tender of the Year" contest. She loses when she refuses to throw out a drunk, telling Duffman that she slept with him to get out of participating in that part of the contest (Duffman's response: "Duffman says a lot of things! Oh, yeah!")
* Like every female character, and some of the heftier guys, in [[http://www.youtube.com/watch?v=HxdA9_BLyVE&feature=mfu_in_order&list=UL this]] Confused.com commercial.
* ''WesternAnimation/RegularShow'':
** In the episode "Muscle Woman", both Starla AND Muscle Man get this a lot, effectively squickifying the episode.
** The episode "Bald Spot" features Muscle Man gainaxing ''as a plot point.'' Specifically, he kept flexing his pecs (which translates in this case to jiggling his manboobs) throughout the ''entire'' episode in order to distract Starla from his bald spot on his head.
* ''WesternAnimation/FamilyGuy'''s interpretation of [[http://www.youtube.com/watch?v=53CCyomA2u8 SabadoGigante.]]
* {{Zatanna}} does it in the BatmanColdOpen to the ''WesternAnimation/BatmanTheBraveAndTheBold'' episode "Chill of the Night!".
* ''WesternAnimation/AvatarTheLastAirbender'' does small amounts of this with shadows. Rather than showing the actual breasts jiggling, the shadows do it instead. It can be quite hard to notice most of the time, and it's only very slight, but it's still something of a {{Fanservice}} ParentalBonus
* Averted in ''WesternAnimation/TheLegendOfKorra'', however. Although Korra is a relatively busty young woman and her breasts do move around when she's in action, the "breast physics" are very realistic and not Gainaxish at all. It seems more like just part of the animators' meticulous attention to detail than any sort of fanservice.
* Bob Clampett's directed Mr. Hook cartoon "Tokyo Woes" features a rather ample young lady walk across the screen [[IncrediblyLamePun in full swing]] as the eponymous Mr. Hook contemplates what he needs after the war. [[http://youtu.be/Rieb-xDvPxI?t=3m41s Look at the lust in the boy's eye! ]]
* In ''WesternAnimation/{{Archer}}'', Lana's bust is quite jiggly.
* [[MsFanservice The Bimbettes]] in ''Disney/BeautyAndTheBeast'' are quite... bouncy.
* ''WesternAnimation/SpongebobSquarepants'': In the episode "Party Pooper Pants", this happens to Minnie Mermaid at Patchy's party. Because this is live action, it is obviously more realistic than the rest of the examples in this folder.
