Gag Boobs is another ancient trope that has serious misuse problems. It's for large boobs played for laughs in some way but is more often used for giant boobs in general. A wick check is here and it's bad. I found five examples of giant breasts played for laughs (and two borderline examples that may qualify with a rewrite) out of 64 examples on 52 pages. All the other examples were either just giant boobs in general, sinkholes, or ZC Es.

I suspect the name is part of the problem and think a rename at minimum is the best option. As a proposed name, Hilariously Large Bosom might work (though that may draw similar misuse) or Large Boob Comedy. Alternatively, we could rename and expand the trope to include all examples of breasts in general being used for comedy, instead of just limiting it to large boobs. In which case, I would suggest naming it something like Boob-Based Gag, Comedic Boobs, or something similar.

If it's decided to cut/redirect/disambig the page, unless I'm explicitly forbidden from doing so, I'll grab any examples of boobs being used for comedy and see if there's enough for a TLP. if there is, I'll go ahead and run it.

BTW, the trope description itself admits to widespread trope decay. From there: "Contrary to what widespread Trope Decay would have us believe, this trope is not synonymous with "any pair of breasts bigger than a D cup", but refers specifically to large breasts regularly and intentionally used to comedic effect."

• (Laser Hallway) In Good Luck Ninomiya Kun, this trope is combined with gag boobs to comical effect. After much careful sidestepping, eventually Tsukimura Mayu's breast obscures one of the (sensory-only) beams and sets off the security response. Needs a rewrite, though
• (Characters.Ladies Versus Butlers) Gag Boobs: Selnia boobs are the main source of this. For example, in episode 5, when Sanae trips once again falling onto Akiharu, dessert from his tray lands on Selnia's chest. And it was standing. Even lampshaded by both Tomomi and Akiharu. Again, could stand a rewrite
• (Characters.Skullgirls Main Characters) Gag Boobs: Certainly not as Gag-worthy as others, but she measures at 36E and lists "Back pain" as one of her dislikes.
  • It's actually made into a constant visual gag, as many of Valentine's animations have her adjusting her top or supporting her breasts as she pulls items from her cleavage.
  • Eliza makes note of her cup size in her pre-round introduction, rather than trash talking like she would with anyone else.
  Are you blessed by Taweret^note The Egyptian goddess of womanly fertility, or a scalpel? Borderline
• (VideoGame.Tales Of Xillia) Gag Boobs: Not in a direct way, while Milla has big knockers, they instead use Jude's lack of knowledge about that for humor (TEACH ME ABOUT BAZONGAS!). After all, 'bazongas' is a slang word for 'boobs'. Definitely could stand to get more detail, though
• (VisualNovel.High School Romance Magi Trials) Gag Boobs: When turned into a girl, Shaun finds himself with rather big mammaries. Both he and Charlie poke fun at their size, the latter at one point claiming that she could use them as cupholders.

• (Acceptable Religious Targets) Family Guy (after it got renewed) is an incredibly easy target on this very website. A specific example would be the episode "Not All Dogs Go To Heaven". Brian initially seemed to be a deist but as the series wore on (especially after it was Un-Canceled) he was Flanderized into a particularly arrogant atheist. Especially since he's actually met Jesus, and witnessed a pair of miracles performed at Peter's request. This was lampshaded by Stewie in a later episode: "Jesus lived with us for like, a week!"
• (Entertainingly Wrong) Uzaki-chan Wants to Hang Out!: Hana's mother Tsuki Uzaki is all about this. When Hana brings her senpai Shinichi to visit her house and meets him, at one point Shinichi stares at her, and she assumes he's ogling at her (very large) chest, while he's just looking at the cat she has on her lap. Later when she visits Hana at work, a few misunderstandings leave her assuming that Shinichi is a cougar chaser, but after that is cleared up, she overhears Hana and Shinichi talking in a way that makes her believe they're having sex in a storage room (she just accidentally ripped a bag of coffee and spilled the grains). Bottom line, she's somehow convinced herself that Shinichi desires both her and her daughter sexually.
• (Feet-First Introduction 1/2) Who Framed Roger Rabbit: The first thing we see of Jessica Rabbit is one of her legs peeking through a curtain. Followed by one of her breasts.
• (Moe Anthropomorphism 1/2) The notorious OS-tans are moe versions of operating systems and programs; their boob size is often proportional to memory requirements. Windows ME-tan is the Ensemble Dark Horse, who became a popular character for her good intentions but decidedly unstable nature (and her cute Idiot Hair). Windows 2000-tan is a professional, reserved woman, Windows XP-tan has excellent graphical capabilities, and Windows Vista-tan has transparencies and even more memory requirements (except for Basic-tan who's a tsundere little girl). Windows 95-tan is a Yamato Nadeshiko carrying a katana, destroying Microsoft's PC competition once and for all, and eats very little memory. Norton Anti-Virus is portrayed as a lecherous, ghostly doctor who makes the girls strip naked even for the most minor ailments; McAfee as a faith healer; and AVG as a handsome student doctor. Also with theme song.
• (Moe Anthropomorphism 2/2) Habanero-tan is an incredibly cute pepper thing based on a habanero-flavored snack chip. There's also Jalapeño-tan, Habanero-neesan, and Milk-san. Jolokia-tan, the hottest pepper in the world (at the time) is the Alpha Bitch.
• (Anime.Canaan) Running Gag:
  • Yunyun and her, uh... inventive use for pork-buns.
• (Characters.El Santos 2/2) Breast Expansion: She was flatter as a table in the comics, but in the film she gets a pair of bigger assets, due to Tetona being now her boss.
• (Characters.Phantasy Star Online 2 ARKS Guardians) Boobs Of Steel: Any female Player Character with a large chest, of which there are no shortage. And then there's the breast pad accessory...
• (Characters.X Blaze Code Embryo 2/2) Marshmallow Hell: An inevitable result of her glomping someone.
• (JustForFun.Inherently Funny Words) Oppai
• (Memes.Hetalia Axis Powers) Ukraine's "huge tracts of land". Even people who have never heard of the series would probably get the euphemism.
• (PlayingWIth.Video Game Perversity Potential) Straight:
  • Trope Quest has a Level Editor. Players use it to build structures shaped like certain parts of the human anatomy.
• (Podcast.Not Another Dn D Podcast) Big, Thin, Short Trio: Hardwon stands over 6 feet tall though slightly shorter after becoming a half-elf, Moonshine is lean, if top-heavy, and Beverly is a halfling, and a young one at that.

• (Adjustable Censorship) Elvira and the Party Monsters has an option to disable Elvira's more suggestive sound clips. In addition, the game came with a "modesty decal" to cover her Gag Boobs on the backglass.
• (Beach Episode) For about a week, Schlock Mercenary had comics with two female characters (one of whom had Gag Boobs) talking in bikinis. This was lampshaded.
• (Censored Title) The Mexican movie El Santos contra La Tetona Mendoza had to be censored since Tetona is spanish slang for Big Tits. The movie poster had a black box over the word with "Voluptuosa" (voluptuous) written on instead.
• (Feet-First Introduction 2/2) In Brain Dead 13, when Lance stumbles into Vivi's Salon and gets up, the first thing he sees is her neon purple high-heeled shoes before the camera pans up from her legs to her Gag Boobs, and finally to a close-up of Vivi herself, looking at her facial mirror.
• (Sarashi) Ryuubi wears those under her martial arts uniform in Ikki Tousen Dragon Destiny to keep her ENORMOUS breasts under check. Of course, it only works to a degree.
• (A-Cup Angst.Videogames 1/2) Fire Emblem: Awakening: In her special CG in the Summer Scramble DLC, Cordelia is mortified by how much her swimsuit shows off—namely, that it reveals that her breastplate doesn't actually hug her breasts.
  • In Fire Emblem Warriors, a cut conversation between Cordelia and the much more well-endowed Camilla would've addressed this with Camilla remarking that Cordelia has many other fine physical features.
• (Anime.Strange Love) Gag Boobs: Chizuru is incredibly stacked for a girl so rail thin, a fact that gets mocked ruthlessly on Anime Abandon when Sage compares her to a "G-Cup version of Olive Oyl" from Popeye.
• (Bowdlerise.Western Animation) Boomerang UK has no problem airing the Mr. Bean: The Animated Series episode "Bean in Love" with the busty and bouncy Roxy, but they cut out the part where she puts Bean's pencil in her Victoria's Secret Compartment. Oddly, Nicktoons UK aired it uncut.
• (Characters.Aesthetica Of A Rogue Hero) Gag Boobs: Her breasts are so big that it's rather difficult to find shirts and jackets that fit her. Her shirts tend to rip or pop buttons.
• (Characters.Bleach Visoreds And Exiled Soul Reapers) Gag Boobs: Subjects a teenaged Byakuya to Marshmallow Hell as a way of greeting him in the Turn Back The Pendulum arc, and while her chest isn't as big as Matsumoto's or Orihime's it's still big enough to warrant Yachiru nicknaming her "Boobies". Best fits here, IMO
• (Characters.Kan Colle Four) Gag Boobs: Due to the unusual size of her breasts even when unremodeled, she is often seen bouncing with them in fanworks. Also includes a fan reaction in what is supposed to be an objective trope
• (Characters.Our Last Crusade Or The Rise Of Anew World 1/3, subbullet) Gag Boobs: Mismis literally can't keep her balance while running because of them, Nuff said. Also her petite stature only makes her already impressive bust look even larger! Could easily fit in the first category with a rewrite
• (Characters.Our Last Crusade Or The Rise Of A New World 2/3) Even the Girls Want Her: While visiting Lord Mask, his maids are let mouth agape as the shadow of her breasts eclipses them.
• (Characters.Our Last Crusade Or The Rise Of A New World 3/3) Gag Boobs: In Chapter 27 of the manga, Lord Mask's maids are in awe at the sight of her breasts. The Sexy Silhouette that they cast in the same panel is rather exaggerated.
• (Characters.Time Stop Brave) Gag Boobs: Her breasts are ridiculously huge, which Sekai frequently lampshades.
• (Characters.Valkyria Chronicles 4 Squad E 1/3) Bare Your Midriff: Riley's summer swimsuit does this, and it's the part of her body the swimsuit emphasizes the most as opposed to Kai's emphasizing her rear and Minerva's emphasizing her Gag Boobs.
• (Characters.Valkyria Chronicles 4 Squad E 2/3)Gag Boobs: It's obvious from the start that they're big, since even her uniform can't hide them. But the only way you'll get to see just how big they truly are is with the "Squad E, to the Beach!" DLC. Even Raz, who usually only has eyes for Kai, couldn't help staring or shouting his appreciation for Minerva's massive mammaries.
• (Characters.Valkyria Chronicles 4 Squad E 3/3) Third-Person Seductress: Once she's unlocked, her Gag Boobs can be clearly seen from many angles, and they have a notable bounce to them. After her swimsuit is attained in the DLC, she becomes the epitome of this, as her bikini is so revealing that the camera can be rotated to explore every inch of her, from her legs and thighs, toned midriff, and of course her Boobs Of Steel. She also doesn't lose the glasses.
• (Characters.Wings Of Dawn) Gag Boobs: Dawn makes a quick comment that no one on board could match Leona in the chest department.
• (Characters.X Blaze Code Embryo 1/2) Gag Boobs: Easily the bustiest chararacter in XBlaze. She actually looks like she could rival Litchi.
• (Fan Nickname.Hololive 1/2) Moons - The Moonafics' nickname for Moona's Gag Boobs, in a similar nature to Sana's "Jupiters".
• (Fan Nickname.Hololive 2/2) The Ground Pounder/Watson's Shaft - This is what fans call the dirt platform Gura made when she was pranking Amelia in Minecraft by adding Gag Boobs to her pixel-art statue. After the installations were done, she made said platform waist-high and center so she could review her work and only realized what she did when she fell off it, got back up and took a look from below the shaft. Seen here.
• (Fanfic.Big Human On Campus) Gag Boobs: Kurumu; Female Ranma's breasts have been described as big as Kurumu's.
• (Funny.Caddicarus Main Seasons 8 To 13) Caddy briefly talks about how young kids and games usually ends in "total cocking disaster", showing a bunch of games targeted at said demographic. In there, however, one can see a game with a huge-breasted woman in a bikini on the box, complete with it advertising "bouncin' boobs technology". ^explanation Viewers of Brutalmoose might recognise it as Lula 3D, a game that is decidedly not for kids.
• (Funny.Lucifer 2016) Lucifer's hilariously childish drawing of Chloe, complete with Gag Boobs.
• (Funny.Markiplier FNAF) Part 9:
  • Mark interrupts the action to show off a Christmas gift he got from Amy: a Lady Dimitrescu mousepad that includes textured Gag Boobs.
• (Funny.Musical Hell) In the commentary track, Christi on the well-endowed singer:
  Diva: With those flotation devices in her chest, she probably survived the sinking. Seriously, some Italian animator was indulging himself!
• (InMyLanguageThatSoundsLike.Real Life Japanese) In the same way, Korean and Japanese have some words which sound similar but differ in meaning:
  • Korean Oppa (big brother) sounds similar to Oppai (Japanese for Big Boobs).
• (Manga.Machimaho I Messed Up And Made The Wrong Person Into A Magical Girl) Gag Boobs: Nako has a huge rack that Kayo can't stop getting bothered to look at, calling her "tits for brains".
• (Series.ANT Farm 2/2) Running Gag: Although all of the A.N.T.s have been in costumes at various times, Olive does this way more than the rest of them, Examples included:

  • A Nightclub singer circa 1930 with Yogurt-filled Gag Boobs. Why it's a third level bullet, I don't know

• (TheSimpsons.Tropes S To Z) Sexy Backless Outfit:
  • In the "Large Marge" episode (which involved her getting Gag Boobs and becoming a Booth Babe), Marge Simpson wears a sexy backless red dress that emphasizes her new "attributes" for a public appearance.
• (WesternAnimation.The Black Cauldron) Gag Boobs: Orwen of the three witches, who is on the heavier side and well-endowed enough to lose track of a frog in her cleavage. Could end up in the first category with some rewriting by someone familiar with the work
• (YMMV.Paper Mario The Thousand Year Door) Character Perception Evolution: Madame Flurrie was widely hated at first. Not only was her design very unusual for the Mario series, being a humanlike cloud spirit with Gag Boobs and Gag Lips, but she was also derided as weak compared to the game's other partners. Her two attack skills, Body Slam and Lip Lock, were both single-target, and Gale Force was seen as a Useless Useful Spell that many players assumed would instantly KO enemies at the cost of not receiving experience, since that's how One-Hit KO skills worked in the first game. However, as the years went on, it became better known that not only does Gale Force award experience for each enemy KO'd with it, making it more worth using, it has a high success rate against aerial enemies—including some of the most challenging foes in the Bonus Dungeon. In addition, her defense-piercing, self-healing Lip Lock skill is more recognized for its ability to help her tank powerful blows. Now she's more of a Base-Breaking Character: some fans still hate her design or find her moves too gimmicky for their taste, but her ability to easily defeat difficult foes in a single attack and stand on her own against tough bosses is more recognized.

• (A-Cup Angst.Videogames 2/2) Mayu Uzaka of Lightning Legend: Daigo no Daibouken is very conscious about her cup size, and demeaning her this way is her Berserk Button. Of course, this is used for maximum comedy during her encounters with resident snarky Gag Boobs character Misa Atago. There's even an unlockable concept art where Mayu and Misa are wearing swimsuits, and in which Mayu has a jealous look towards Misa's rack.
• (Characters.Devil Survivor 2 Party Members) Gag Boobs: In the peeping scene, it's directly acknowledged that "she wins".
• (Characters.El Santos 1/2) Gag Boobs: Heck, her name means Big-titted in Spanish. Bolding theirs
• (Characters.Fairy Without Wings Mermaid Heel) Gag Boobs: Kagura isn't exactly flat and yet supposedly Undine makes her feel inadequate.
• (Characters.Gantz Other Teams 1/2) Gag Boobs: Which her team's Gantz very much appreciates.
• (Characters.Gantz Other Teams 2/2) Gag Boobs Found already commented out
• (Characters.Rosenkreuzstilette) Gag Boobs: When Strudel nestles herself into Sichte's cleavage after Freudia defeats her.
• (Fanfic.Thawing Permafrost) Gag Boobs: Kurumu. Kind of a given.
• (Series.Ant Farm 1/2) Gag Boobs: It's a part of Olive's disguise in the pilot.
• (Series.Spitting Image) Gag Boobs: Claire Rayner.
  • Madonna: in one sketch nobody notices her until she shows them.
• (VideoGame.Cyborg 2007) Gag Boobs Already commented out
• (Webcomic.Busty Girl Comics) Gag Boobs: Invoked and deconstructed.
• (Webcomic.Fletcher Apts) Gag Boobs Already commented out

... "Assets" slang, however. 'Comedic "Assets"'? Too vague.
