History Memes / Undertale

* "call it knochen könig and have it be for storyshift sans" [[labelnote:Explanation (spoilers)]]On [=SoundCloud=], some fans make remixes of the game's music where they combine certain characters' leitmotifs with other characters' leitmotifs for fanmade [[AlternateUniverse AUs.]] There's a bit of a [[BrokenBase debate]] over whether "Megalovania" is Sans' leitmotif, Genocide Chara's leitmotif, or the Anomaly's leitmotif. And fans who think it's Chara's theme would make remixes of "Bergentrückung" and "Asgore" and apply "Megalovania" to it, and fans who think it's Sans' theme would harass the uploaders telling them to rename it to "Knochen König", which is German for "Bone King". And people eventually just started jokingly saying it on remixes of completely different songs.[[/labelnote]]

* "You're blue now. That's my attack!" [[labelnote:Explanation]]Papyrus' famous "blue attack" turns your SOUL blue.[[/labelnote]]
* "Sans! Stop plaguing my life with X!" [[labelnote:Explanation]]The original line was "incidental music." When Papyrus discovers that his bone collection has been stolen by the Annoying Dog, Sans pops his head out of his room just to play LosingHorns for the occasion. Papyrus responds with this line.[[/labelnote]]

* "Undyne suplexes a huge boulder, just because she can." [[labelnote:Explanation]]One of the descriptions in the dialog box during the fight with Undyne reflecting her {{Hot Blooded}}-ness.[[/labelnote]]
** "Undyne suplexes a _____, just because she can."
** "Undyne suplexes herself, just to prove that nothing is impossible."

* OOHH YEEES~ [[labelnote:Explanation]]Mettaton [[SuddenlyVoiced says]] this in a very sexual manner upon transforming into his [[BishonenLine EX form]]. It's one of the very rare quotes in the game not to use VoiceGrunting. His "YEAH," the sound he makes when you hit him during his boss battle, also qualifies as a meme, although it's less common.[[/labelnote]]
* Similar to Papyrus, anyone familiar with WebVideo/{{Markiplier}} tends to use his voice for Mettaton.

** On a similar note, the cynical and surprisingly badass gem: "I can't go to hell. I'm all out of vacation days."

* Misremembering Heats Flamesman's name.

** [[https://www.youtube.com/watch?v=CaPrrncGo3M Don't touch the Child!]] [[labelnote:Explanation]] from the ending of Underpants' true ending, where Toriel, a Royal Guard, and then all the monsters beat up Flowey (and later Asgore) for hurting Frisk. [[/labelnote]]

* shut up loser (GASTER BLAST)[[labelnote:Explanation]]A reaction image with Gaster that started getting spread in 2023.[[/labelnote]]

* Similar to Papyrus, anyone familiar with LetsPlay/{{Markiplier}} tends to use his voice for Mettaton.
** Even LetsPlay/{{Markiplier}} himself decided the character sounded like him… leaving him to do an impression of himself for all Mettaton's dialogue.

* Undying [=ZUNpets=] / Undyne the unused Touhou Boss. [[labelnote:Explanation]] In a recent crossover meme with the Franchise/TouhouProject a lot of people have noticed how Touhou's memetic "[=ZUNpets=]" sound extremely similar to the Trumpets used in Undyne's "Battle Against A True Hero" boss theme. Not only that, but Undyne is one of the definitive difficulty spikes in Undertale's Genocide run, so people commonly joke that Undyne channeled her inner Touhou to make the Bullet Hell segments of her bossfight much harder. [[/labelnote]]

* Don't sexualize goat mom. [[labelnote:Explanation]]Shortly after the game's release, Toriel became a prominent source of {{Rule 34}} primarily from the UsefulNotes/FurryFandom. This is a common response to said smut, or a message not to make it.[[/labelnote]]
* "if you were the toriel cosplayer who gave me a blowjob at dragoncon, PLEASE inbox me. i think you took my wallet. it looks like an NES" [[labelnote:Explanation]]An infamous Tumblr post. Nothing more can be said, aside from the fact that it's fake ([=DragonCon=] occurred ''before'' the game's release).[[/labelnote]]

* Papyrus is [[WesternAnimation/SpidermanIntoTheSpiderVerse Uncle Aaron]].[[labelnote:Explanation]] [[https://twitter.com/Clocky99565893/status/1672824219258744832 A Twitter user noticed]] that Uncle Aaron has a similar head shape as Papyrus. This has lead to memes and edits about them secretly being the same person, in a similar vein as the "Steven After Not Surviving" meme about Sans, often with acronyms like "Prowler After Perishing".[[/labelnote]]

* Let Papyrus say fuck day [[labelnote:Explanation]]On Tumblr June 16 is "Let Papyrus say fuck" day, with fanart of Papyrus saying fuck

* Let Papyrus say fuck day

* WesternAnimation/{{Steven|Universe}} [[FunWithAcronyms After Not Surviving]] [[labelnote:Explanation]]Someone ([[https://www.youtube.com/channel/UCzysEHp6XaSBji4FEjYn1LQ LouLouVZ]], creator of ''Webcomic/{{Spaicy}}'') [[https://imgur.com/eMDvDUa posted]] what was ([[PoesLaw probably]]) a parody of the more outlandish theories, suggesting that Sans is Steven Universe after dying of cancer. Naturally, this sparked a further escalation of [[SerialEscalation increasingly absurd]] fan "theories" trying to one-up each other in terms of sheer implausibility, leading up to acronyms like "Secretly Actually [[VideoGame/{{Earthbound}} Ness]] Skeleton" (see above) or "WesternAnimation/{{Shrek}} After Nuclear Strike." This meme would later on be referenced in ''Deltarune's'' "$pamton's $weepstakes" event where one of the items in the website for the event (a jar of white sand with a pink ball and a yellow ball) was referred to as "Spamton After Not Surviving".[[/labelnote]]

* [[http://knowyourmeme.com/memes/monika-t-posing-over-sans This image]] of [[VisualNovel/DokiDokiLiteratureClub Monika]] T-Posing over Sans. [[labelnote:Explanation]]A fan art made by sansurichin, the pose is used to depict dominance from one side (Monika) and the other side cowering in fear (Sans). As ''DDLC'' came to be another genre-subverting SurpriseCreepy game of the later 2010's, the similarly [[MetaGuy meta-aware Monika]] came to become as memetic as her peer Sans. Monika's full-blown BreakingTheFourthWall habits made her incredibly GenreSavvy even in comparison to Sans, thus the joke being that a random high school girl was able to intimidate a MemeticBadass into submission. Label edits of this particular image became very, very popular soon after.[[/labelnote]]

* Undying [=ZUNpets=] / Undyne the unused Touhou Boss. [[labelnote:Explanation]] In a recent crossover meme with the Franchise/TouhouProject a lot of people have noticed how Touhou's memetic "[=ZUNpets=]" sound extremely similar to the Trumpets used in Undyne's "Battle Against A True Hero" boss theme. Not only that, but Undyne is one of the definintive difficulty spikes in Undertale's Genocide run, so people commonly joke that Undyne channeled her inner Touhou to make the Bullet Hell segments of her bossfight much harder. [[/labelnote]]

** "Would you smooch a goat?" [[note]]An offshoot of the above meme, based around the Dreemurs.[[/note]]

* Foam Shower [[labelnote:Explanation]]For the Undertale/Deltarune Newsletter on April 1, 2023, Toby Fox randomly sent multiple photo of himself in swim trunks covered in foam to 1,000 random subcribers, claiming that they were accidentally added to the "Foam Shower" tier. This image received many edits and memes due to its bizarre nature.[[/labelnote]]

* "The internet! I'm quite popular there!" [[labelnote:Explanation]]In-universe, this is just Papyrus being a [[ComicallyMissingThePoint comically oblivious]] SmallNameBigEgo as usual. He's twelve away from a double digit follower count; think about that for a second. [[FridgeLogic How did Papyrus get -2 followers?]] ''Out-of-universe'', he's possibly second only to his brother in overall popularity among the ''Undertale'' cast.[[/labelnote]]

* Baby Bones [[labelnote:Explanation]]A post on Undertale's subreddit showed an image from the game of Sans saying that Junior Jumble is for "Baby Bones", with the poster misinterpreting this line and asking if Baby Bones is the third skeleton brother. This has led to many other posts about Baby Bones or other posts wildly misinterpreting out of context lines from the game.[[/labelnote]]

* [[NudeColoredClothes Chara's flesh stripe.]][[labelnote:Explanation]]Due to [[{{Retraux}} the limited color palette]] of Chara's sprite, the stripe on their shirt is the exact same color as their skin. This has led to all sorts of alternative interpretations of their appearance, from Chara wearing a [[BareYourMidriff crop top]] to [[GenuineHumanHide their clothes being made of flesh]].[[/labelnote]]

!!Mettaton:

!!Asgore:

* Flowey:
** "[[UnusualEuphemism Friendliness Pellets]]". [[labelnote:Explanation]]Flowey attempts to trick the player at the beginning of the game by telling them to touch his deadly magic bullets, saying that they're actually "friendliness pellets" that monsters communicate with. It's Flowey's EstablishingCharacterMoment, so they're often connected to him and "LOVE" in general.[[/labelnote]]
** "In this world, it's kill or be killed". [[labelnote:Explanation]]One of Flowey's first, most memorable, and also [[CatchPhrase most frequently used]] phrases. Much like Sans' "do you wanna have a bad time?", this phrase is frequently altered and accompanied with a conksuck drawing of Flowey or paired with an image of a flower with a face.[[/labelnote]]
*** It also spawned a lot of derivatives following the format "In this world, it's [X] or be [X]ed".
** Omega Everyone [[labelnote:Explanation (spoilers)]]As the final boss of the Neutral route, Flowey gains a [[OneWingedAngel monstrous]] [[ArtShift photorealistic form]] known as "Photoshop Flowey" or more commonly "Omega Flowey". It is common for fanartists to create similar Omega forms for other characters, such as [[http://i2.kym-cdn.com/photos/images/original/001/042/276/406.gif Temmie]], [[http://i0.kym-cdn.com/photos/images/original/001/056/640/60d.png Papy]][[http://i1.kym-cdn.com/photos/images/original/001/057/004/471.png rus]], [[http://i2.kym-cdn.com/photos/images/original/001/057/318/7dc.png Aaron]], [[http://i2.kym-cdn.com/photos/images/original/001/057/319/ab5.png Woshua]], [[http://i0.kym-cdn.com/photos/images/original/001/048/981/4c8.jpg Burgerpants]], [[http://i2.kym-cdn.com/photos/images/original/001/056/961/544.gif Lesser Dog]]... and [[http://i2.kym-cdn.com/photos/images/original/001/054/866/873.png Donald Trump]]?[[/labelnote]]
** ______ is now playing Undertale\\

** Big [[PrecisionFStrike boner]] down the lane [[labelnote:Explanation]]A silly-sounding DummiedOut bit of text in the game's files. The phrase gained popularity after a [[https://www.youtube.com/watch?v=Bo5l_lbfxJ4&t=580s video of a corrupted version of the game]] showed Flowey saying it right before his boss fight.[[/labelnote]]
** But it refused. [[labelnote:Explanation (spoilers)]]In Asriel Dreemurr's fight, dying will cause your SOUL to break apart, but it refuses to die and continues the fight. The text accompanying it, "But it refused.", has been used for strength and encouragement in the fandom, and is also used whenever something that someone doesn't want to happen occurs anyway, and vice versa.[[/labelnote]]
** Wide Asriel [[labelnote:Explanation (spoilers)]]When Asriel transforms into his final form, he briefly widens his body. This scene is often compared to the "Wide Presidents Walking" meme.[[/labelnote]]
** Emo Asriel and his edgy OC [[labelnote:Explanation (spoilers)]]Asriel is often portrayed in not-so-serious fanworks as an EmoTeen, and his final form (and less commonly, Photoshop Flowey) is often joked to be his OC that he created before he died, to the point that some treat it as {{Fanon}}. Became HilariousInHindsight when the artbook revealed that Toby Fox considered giving him "boyband hair".[[/labelnote]]
* Toriel:
** Goat Mom is Best Mom. [[labelnote:Explanation]]Although a clear example of MyBelovedSmother, she really does want only the best for the protagonist. Today, there's tons of art showing her being genuinely motherly to either the protagonist, or other characters.[[/labelnote]]
** Don't sexualize goat mom. [[labelnote:Explanation]]Shortly after the game's release, Toriel became a prominent source of {{Rule 34}} primarily from the UsefulNotes/FurryFandom. This is a common response to said smut, or a message not to make it.[[/labelnote]]
** "if you were the toriel cosplayer who gave me a blowjob at dragoncon, PLEASE inbox me. i think you took my wallet. it looks like an NES" [[labelnote:Explanation]]An infamous Tumblr post. Nothing more can be said, aside from the fact that it's fake ([=DragonCon=] occurred ''before'' the game's release).[[/labelnote]]
** [[https://twitter.com/nanamisegg/status/662782447009009665 Toriel vaping.]] [[labelnote:Explanation]]More specifically, pictures of a person in a Toriel fursuit vaping that caught on due to how much it [[OutOfCharacterMoment contrasts with Toriel's personality.]][[/labelnote]]
** tuTORIEL [[labelnote:Explanation]]A portmanteau of tutorial and Toriel. This is usually inserted into Undertale tutorial videos as a comment. Ended up reaching AscendedMeme status in ''VideoGame/{{Deltarune}}'', where Chapter 2 sees Kris' prison cell in Queen's mansion decorated with items based on their search results, including two piano-playing Toriel holograms because they searched "video game piano tutoriel".[[/labelnote]]
** Homophobic Toriel. [[labelnote:Explanation (spoilers)]]Some players have noticed that Gerson talks about how Toriel and Asgore used to display affection in public when they were married, while Toriel stops Undyne and Alphys from kissing in front of Frisk in the True Pacifist Route. Fans have started jokingly theorizing that this means that Toriel is homophobic, and the reason she and Asgore are divorced in ''VideoGame/{{Deltarune}}'' is because she disapproved of Asgore's feelings for Rudy.[[/labelnote]]
** my child you are breaking my [[red:heart]] [[labelnote:Explanation]]In the [[https://m.youtube.com/watch?v=1Hojv0m3TqA release trailer]], there's a scene where a CGI Toriel crashes into blocks with the above text, with the text "Probably not actual game footage?" under it. Needless to say, [[TrailersAlwaysLie this scene isn't actually in the game]]. This scene is probably the trailer's most well-known scene due to its absurdity, and the CGI Toriel has since also appeared in the Nintendo Switch trailer and the 6th anniversary livestream.[[/labelnote]]
* Papyrus:
** "That's the trash can. Feel free to visit it any time." [[labelnote:Explanation]]Papyrus says this during the date if you examine his trash cans. Fans have re-appropriated it for a variety of purposes, the most popular being the "Sans dies first and Papyrus becomes a vengeful badass" {{Fanon}} as his variant of the "get dunked on" quote above.[[/labelnote]]
** "The internet! I'm quite popular there!" [[labelnote:Explanation]]In-universe, this is just Papyrus being a [[ComicallyMissingThePoint comically oblivious]] SmallNameBigEgo as usual. He's twelve away from a double digit follower count; think about that for a second. [[FridgeLogic How did Papyrus get -2 followers?]] ''Out-of-universe'', he's possibly second only to his brother in overall popularity among the ''Undertale'' cast.[[/labelnote]]
** "I didn't cry! I just… [[SandInMyEyes caught something in my eye]]." "What did you catch?" "'''TEARS'''!" [[labelnote:Explanation]]An exchange between Papyrus and Sans that's used when referring to the [[TearJerker sadder]] moments of the game.[[/labelnote]]
** Papyrus and [[TrademarkFavoriteFood spaghetti]]. It's become a symbol for him.
** "Oh, no! You're meeting all my standards!" [[labelnote:Explanation]]If you flirt with Papyrus at the beginning of the battle, he asks what your redeeming qualities are, warning you that he has very high standards. Regardless of what you choose (and your choice is between "I can make spaghetti" and "I have zero redeeming qualities") he reacts with this line, which is used as a form of SelfDeprecation on the fandom's part whenever they find someone sharing their interests.[[/labelnote]]
** "You're blue now. That's my attack!" [[labelnote:Explanation]]Papyrus' famous "blue attack" turns your SOUL blue.[[/labelnote]]
** "Sans! Stop plaguing my life with X!" [[labelnote:Explanation]]The original line was "incidental music." When Papyrus discovers that his bone collection has been stolen by the Annoying Dog, Sans pops his head out of his room just to play LosingHorns for the occasion. Papyrus responds with this line.[[/labelnote]]
** Referring to [[https://tcrf.net/images/1/1b/Undertale_Papyrus_concept_art.png concept art Papyrus]] with various bastardized names such as the Alright Papyrus, Papaya, Paperpenis, or Popeye.
** [[DespairEventHorizon Papyrus no longer believes in you / "I'm going to have LOTS OF FUN!"]] [[labelnote:Explanation (spoilers)]]Two quotes mentioned within videos of [[AlternateUniverse Genocide Papyrus]], the first connecting with his Genocide theme, [[https://www.youtube.com/watch?v=UWoXEumwQXM Disbelief]], and the comic video, [[https://www.youtube.com/watch?v=Et2rvbpPx_w Papyrus no longer believes in you]], while the other comes from the comic video itself.[[/labelnote]]
** Nobody kills Papyrus / The hardest boss of Genocide run. [[labelnote:Explanation]]Papyrus has developed a reputation for making Genocide runs very difficult — not because he's hard, far from it (on Genocide, he immediately spares you and refuses to attack), but because players simply ''cannot'' bring themselves to harm Papyrus.[[/labelnote]]
** Reading Papyrus' dialogue in [[WesternAnimation/HeManAndTheMastersOfTheUniverse1983 Skeletor's]] voice is practically a requirement now.
** "Papyrus, what's your favourite food?" [[labelnote:Explanation]]On the one-year anniversary of ''Undertale''’s release, Toby Fox made a [[https://undertaleqa.tumblr.com/ Q&A blog]] where he proceeded to answer ten user-submitted questions. The submission page used an example of "Papyrus, what's your favourite food?" At least ten users submitted that as their questions, and [[TrollingCreator Toby ended up only answering that question]].[[/labelnote]]
** RED X ARE IMPASSABLE! YOU CANNOT WALK ON THEM! YELLOW X ARE ELECTRIC! THEY WILL ELECTROCUTE YOU! etc. [[labelnote:Explanation]]Whenever Undertale fans see a picture of a bunch of colored squares, or pretty much anything that comes in a lot of colors, it's pretty common to see comments quoting Papyrus' explanation for the tile puzzle's rules.[[/labelnote]]
* Undyne:
** "Undyne suplexes a huge boulder, just because she can." [[labelnote:Explanation]]One of the descriptions in the dialog box during the fight with Undyne reflecting her {{Hot Blooded}}-ness.[[/labelnote]]
*** "Undyne suplexes a _____, just because she can."
*** "Undyne suplexes herself, just to prove that nothing is impossible."
** "ANIME'S REAL, RIGHT?!?!"
*** ♥ Anime is real
*** Anime is not real. [[labelnote:Explanation (spoilers)]]At the end of the "date" with Alphys, Undyne has a brief crisis when she's faced with the possibility that [[{{Otaku}} "human history"]] is not actually truthful, and asks you the truth in her panic. [[MundaneMadeAwesome It's given as much attention as some far more important choices in the game]], and the sheer ridiculousness has led to this question being tossed around as SeriousBusiness. Also, anything relating to Undyne the Undying will be met with at least one person saying that, yes, anime ''is'' real.[[/labelnote]]
** Her [[MundaneMadeAwesome cooking methods]]. Mostly because it connects with Papyrus and his spaghetti.
** "WELL??? Are you CHERISHING??? CHERISH HARDER!!!" [[labelnote:Explanation]]If you befriended Undyne and call her in the room with the bird that flies you over a disproportionately small gap, she tells you to cherish the bird. Calling her again causes her to say this line. Fans of course adapted it to cherishing all kinds of things.[[/labelnote]]
** Fish Vriska [[labelnote:Explanation]]Undyne bears many resemblances to Vriska Serket of ''Webcomic/{{Homestuck}}'', both in appearance and personality.[[/labelnote]]
** Undying [=ZUNpets=] / Undyne the unused Touhou Boss. [[labelnote:Explanation]] In a recent crossover meme with the Franchise/TouhouProject a lot of people have noticed how Touhou's memetic "[=ZUNpets=]" sound extremely similar to the Trumpets used in Undyne's "Battle Against A True Hero" boss theme. Not only that, but Undyne is one of the definintive difficulty spikes in Undertale's Genocide run, so people commonly joke that Undyne channeled her inner Touhou to make the Bullet Hell segments of her bossfight much harder. [[/labelnote]]
* Mettaton:
** Mettaton going "Awooga." [[labelnote:Explanation]]A joke he makes if you compliment his voice during his boss battle — he has the ''voice of a siren,'' see.[[/labelnote]]
** Mettaton's flamboyant posing is a meme in and of itself, often being compared to ''Manga/JoJosBizarreAdventure'' or Music/DavidBowie.
** "Would you smooch a ghost?" [[labelnote:Explanation (spoilers)]]Partway through Mettaton's quiz, he asks the player this question, and rigs it so that it can't be answered with anything but "Heck Yes", because Mettaton ''is'' a ghost and is inflating his ego as usual. Fans use it for both Mettaton himself (mainly his attractive EX form), as well as resident adorable ghost Napstablook.[[/labelnote]]
*** "Would you smooch a goat?" [[note]]An offshoot of the above meme, based around the Dreemurs.[[/note]]
** Mettaton's legs. [[labelnote:Explanation (spoilers)]]It's become popular to add his EX form's legs onto other characters from the game (mainly Sans, for the comedy inherent in his being one of the shortest characters). Possibly in response to his line, "Who needs arms, with legs like these?" if you remove his arms during the battle.[[/labelnote]]
*** ''leg so hot, hot hot leg, leg so hot, you fry an egg.'' [[labelnote:Explanation]]This predates ''Undertale'' by at least a few years, but it seems to have become the standard response to anything that involves Mettaton's legs.[[/labelnote]]
** Mettaton NEO is infamous for being a literal ZeroEffortBoss despite [[AnticlimaxBoss looking awesome and having a badass buildup]]. Many [=YouTube=] videos and Vines exist dedicated to mocking how ridiculously easy the battle is. Or, alternatively, to try to give him an opportunity to shine and to [[AdaptationalBadass be a badass]].
*** Some have joked that NEO stands for [[FunWithAcronyms Non-Effective Obstacle]]. However, this joke is dead as of Chapter 2 of ''VideoGame/{{Deltarune}}'', whose secret boss, Spamton NEO, not only is the strongest boss in the chapter, but he even turns NighInvulnerable in the Weird Route.
** OOHH YEEES~ [[labelnote:Explanation]]Mettaton [[SuddenlyVoiced says]] this in a very sexual manner upon transforming into his [[BishonenLine EX form]]. It's one of the very rare quotes in the game not to use VoiceGrunting. His "YEAH," the sound he makes when you hit him during his boss battle, also qualifies as a meme, although it's less common.[[/labelnote]]
** Similar to Papyrus, anyone familiar with LetsPlay/{{Markiplier}} tends to use his voice for Mettaton.
*** Even LetsPlay/{{Markiplier}} himself decided the character sounded like him… leaving him to do an impression of himself for all Mettaton's dialogue.
* Asgore:
** Asgore "You Must Be This Tall To Live" Dreemurr [[labelnote:explanation]]Due to being partially, if not completely, responsible for the deaths of (what were likely) 6 children, the fandom loves to create nicknames [[https://sailorbeefcake.tumblr.com/post/133814953301 like]] [[http://i.imgur.com/bwoL0vu.png these]] for him.[[/labelnote]]
** ASGORE YOU USELESS FUCK [[labelnote:Explanation]]Probably due to [[http://phillip-bankss.tumblr.com/post/131503174249/i-hope-you-dont-have-a-fetish-for-buff-legs-i this]], a common joke is that the barrier isn't that big of a deal like Asgore makes it out to be, and that there were probably several workarounds that he could've used to free everyone instead of waiting for humans to drop in (such as digging under the barrier).[[/labelnote]]
** Asgore Did Nothing Wrong [[labelnote:Explanation]]Asgore's fans have taken it upon themselves to create a counter-meme to the above.[[/labelnote]]
** Asgore "Epic Divorce Man" Dreemurr [[labelnote:Explanation]]The result of a tumblr combining tweets from the infamous "Blog/{{Dril}}" account with pictures from Undertale ([[https://twitter.com/dril/status/333222895100760064 this one]] in particular). Has probably been strengthened with the release of ''Deltarune'', as it seems that Toriel and Asgore's wholesome marriage really does tend to end with the two of them on bad terms in every universe.[[/labelnote]]
** NO MERCY/Asgore Fight In A Nutshell [[labelnote:Explanation]]It's very common to edit videos involving someone smashing an object into bits into parodies of Asgore destroying the Mercy button before his fight, as shown [[https://www.youtube.com/watch?v=r1jNJN77PX0 here]].[[/labelnote]]
** Asgore [[GiverOfLameNames named]] X. [[labelnote:Explanation]]Asgore is quite known for his GiverOfLameNames characteristic, so when there is something named [[ExactlyWhatItSaysOnTheTin absurdly specific]], this is a common response.[[/labelnote]]
** Burgertrucking [[labelnote:Explanation]]A frequent [[RougeAnglesOfSatin misspelling]] of Asgore's pre-battle theme, which led to some fanart of Asgore running a burger truck.[[/labelnote]]
* The Fallen Human/[[HelloInsertNameHere Chara]]:
** 201X/The first human has fallen. [[labelnote:Explanation]]This meme began circulating around New Year's of 2019. Since the year Chara fell down was "[[YearX 201X]]" according to the game's intro, this means that 2019 is the last time ''Undertale'' could have taken place in. [[https://mobile.twitter.com/yukimura_4/status/1212870184647741440 With the revelation that there is an actual Mt. Ebbot in Spain]], people began speculating that Chara had already fallen down the mountain, and that the events of the game will take place in the future. [[https://mobile.twitter.com/tobyfox/status/1212868916881563648 Even Toby Fox got in on this meme.]][[/labelnote]]
** I am [insert something silly] [[labelnote:Explanation (spoilers)]]When you meet [[GreaterScopeVillain Chara]] at the end of a Genocide run, they introduce themself: "I am [player's name]". Fans jumped on the opportunity to humiliate the [[HateSink detested child]] by [[HelloInsertNameHere inputting stupid things at the start of the game]] and [[http://i1.kym-cdn.com/photos/images/original/001/052/703/f33.jpg watching Chara]] [[https://web.archive.org/web/20160414161114/http://i3.kym-cdn.com/photos/images/original/001/061/228/e5a.png insult themself]]. (The latter screenshot is obviously edited, but it's still possible to have Chara say that, minus the rainbow effect. Also note that the fallen child's name cannot exceed six characters without editing the game. However, even with these limitations, [[https://www.reddit.com/r/Undertale/comments/m3v32q/did_an_entire_genocide_run_just_to_make_this_joke/ some still make jokes with the name.]])[[/labelnote]]
*** You're not actually [something stupid], are you? [[labelnote:Spoilers]]Likewise, Asriel's line from the Pacifist route gets [[https://knowyourmeme.com/photos/1044566-undertale abused]] as well.[[/labelnote]]
** '''[[red:No chocolate.]]''' [[labelnote:Spoilers]]A sentence pronounced (or thought) by Chara in red letters [[https://nochocolate.tumblr.com/post/156278132600/why-does-chara-say-no-chocolate-in-the-genocide when looking in Asgore's fridge in a No Mercy run]]. Because of its [[NightmareRetardant silly and unexpected nature]], especially when you think it is [[OmnicidalManiac the character whose obsession is to kill everyone who says that]], the Fallen Human's [[SweetTooth taste for chocolate]] has been [[{{Flanderization}} flanderized]] [[https://www.youtube.com/watch?v=GlMkenmTVq8 to obsession]] [[https://www.reddit.com/r/Undertale/comments/ftoofm/chara_may_be_bad_but_shes_not_evil/ on the]] [[https://www.deviantart.com/allve/art/Chara-Undertale-No-Chocolate-618421690 Internet]], making them a DracoInLeatherPants.[[/labelnote]]
*** Chara hates white chocolate. [[labelnote:Spoilers]]Among chocolate-lovers, white chocolate is frequently compared unfavorably to milk and dark chocolate thanks to it consisting mainly of cocoa butter with no actual cocoa solids. Consequently, several members of the fandom have decided that the chocolate-loving Chara holds similar disdain for white chocolate. [[http://askfriskandcompany.tumblr.com/post/146878684477/do-u-prefer-milk-chocolate-white-chocolate-or An example here.]][[/labelnote]]
** Discussions about Chara's morality are a meme by themselves. While [[https://www.reddit.com/r/CharaArgumentSquad/ some still want to argue peacefully]] ([[TeamSwitzerland or simply refuse to take one side or another]]), two radically opposite "squads" formed to convince every other fan with their ideas:
*** Chara Protection Squad [[labelnote:Explanation (spoilers)]] Because of the longstanding debate over whether Chara/the Fallen Human is actually evil or not, those who believe they are good have labeled themselves the "Chara Protection Squad" (or "[[https://www.reddit.com/r/Charadefensesquad/ Chara Defense Squad]]"). This has crossed over to other works with other Character Protection Squads.[[/labelnote]]
*** Chara Offense Squad [[labelnote:Explanation (spoilers)]] In contrast with the above, those who believe Chara to be truly evil to some degree call themselves "[[https://www.reddit.com/r/CharaOffenseSquad/ Chara Offense Squad]]" in contrast with the ones above, accusing them of being too biased and ignoring important points of the story. They also ask themselves [[https://www.reddit.com/r/CharaOffenseSquad/comments/mvudzp/which_evil_chara_interpretation_do_you_prefer/ how much the Fallen Human really cared for the monsters and their adoptive family.]][[/labelnote]]
** Chara's name debates.[[labelnote:Explanation]]Among the [[BaseBreakingCharacter many aspects of Chara that are hotly debated]], one of the sillier/more minor ones is how to pronounce their name. Fans are split between calling them "Car-a", "Care-a", and "Char-a", although one thing they all seem to agree on is that it should ''never'' be pronounced "Chair-a".[[/labelnote]]
** Comparing (Genocide) Chara to [[VideoGame/{{Hatred}} Not Important]].[[labelnote:Explanation]]They both want to kill everyone, if for wildly different reasons. Also may have to do with how he proclaims "[[HilariousInHindsight My genocide crusade begins here]]" in the teaser trailer for the game.[[/labelnote]]
** [[https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcTHOP0U1vIEJZW0FIgVK_vHmPKQQ_U9dGHwPudYaTnMYloUxRNr4wYlcMfwuQ You can't spell DETERMINATION without TERMINATION.]] [[labelnote: Explanation]] Is sometimes used when players talk about the Genocide run. Most of the time it is pasted over a picture of Chara.[[/labelnote]]
** [[NudeColoredClothes Chara's flesh stripe.]][[labelnote:Explanation]]Due to [[{{Retraux}} the limited color palette]] of Chara's sprite, the stripe on their shirt is the exact same color as their skin. This has led to all sorts of alternative interpretations of their appearance, from Chara wearing a [[BareYourMidriff crop top]] to [[GenuineHumanHide their clothes being made of flesh]].[[/labelnote]]

* Music/TobyFox is either really lazy or a fucking genius. [[labelnote:Explanation]]Most songs in the game's soundtrack share musical phrases with one another, with some being different arrangements of the exact same song. As such, fans have described Toby as both lazy for re-using so many melodies and as a genius for being able to do this so well, given how subtle some of these recyclings are and what their significance is in each song. A few fans also joke that he was too lazy to make something interesting with certain areas, those areas being the useless show rooms of Mettaton during the Genocide run.[[/labelnote]]

** SANS, WHAT ARE YOU DOING? SANS! '''SANS!''' [[BigShutUp SHUT THE]] [[PrecisionFStrike FUCK]] [[BigShutUp UP]], SANS![[labelnote:Explanation]]Papyrus' response to the above.[[/labelnote]]

** Comparing Chara, mainly Genocide Chara to [[VideoGame/{{Hatred}} Not Important]].[[labelnote:Explanation]]They both want to kill everyone, if for wildly different reasons. Also may have to do with how he proclaims "[[HilariousInHindsight My genocide crusade begins here]]" in the teaser trailer for the game.[[/labelnote]]

** EarthBound SoundFont > Overdriven Guitar [[labelnote:Explanation]]The specific sound used for the ostinato used in Megalovania is a sample originally recorded by Shigeru Miyamoto on his guitar for the finale of EarthBound, which in the first stage sports a fairly heavy rock-style boss theme. Being instantly recognisable nowadays due to Undertale's popularity, the extremely compressed sample has become somewhat of an inside joke among those knowledgeable in music production.[[/labelnote]]

* Sans Undertale [[labelnote:Explanation]]Sans' popularity eventually got so intense and overbearing that his fandom caved in on itself, leading to this meme being used to poke fun at him and his remaining fans. It began as just a bastardization of his name, and was later accompanied by a picture of a poorly drawn Sans or another massively popular character from another fandom (most commonly Nagito Komaeda from ''Franchise/{{Danganronpa}}'' who received a similar treatment) badly photoshopped over a picture of the [[spoiler:Judgement Hall at the end of the game]]. Later on, this mutated into anytime Sans, the song Megalovania, or both appear out of nowhere in videos or other games. This meme has since reached a level of ubiquity to the point where pretty much any fictional character you can think of has been referred to as if their last name was the name of the work (written as one compound word if necessary).[[/labelnote]]

** "In this world, it's kill or be killed". [[labelnote:Explanation]]One of Flowey's first, most memorable, and also [[CatchPhrase most frequently used]] phrases. Much like [[spoiler:Sans']] "do you wanna have a bad time?", this phrase is frequently altered and accompanied with a conksuck drawing of Flowey or paired with an image of a flower with a face.[[/labelnote]]

** Wide [[spoiler:Asriel]] [[labelnote:Explanation (spoilers)]]When Asriel transforms into his final form, he briefly widens his body. This scene is often compared to the "Wide Presidents Walking" meme.[[/labelnote]]
** Emo [[spoiler:Asriel]] and his edgy OC [[labelnote:Explanation (spoilers)]]Asriel is often portrayed in not-so-serious fanworks as an EmoTeen, and his final form (and less commonly, Photoshop Flowey) is often joked to be his OC that he created before he died, to the point that some treat it as {{Fanon}}. Became HilariousInHindsight when the artbook revealed that Toby Fox considered giving him "boyband hair".[[/labelnote]]

** "That's the trash can. Feel free to visit it any time." [[labelnote:Explanation]]Papyrus says this during the date if you examine his trash cans. Fans have re-appropriated it for a variety of purposes, the most popular being the [[spoiler:"Sans dies first and Papyrus becomes a vengeful badass" {{Fanon}} as his variant of the "get dunked on" quote above]].[[/labelnote]]

** [[spoiler:[[DespairEventHorizon Papyrus no longer believes in you / "I'm going to have LOTS OF FUN!"]]]] [[labelnote:Explanation (spoilers)]]Two quotes mentioned within videos of [[AlternateUniverse Genocide Papyrus]], the first connecting with his Genocide theme, [[https://www.youtube.com/watch?v=UWoXEumwQXM Disbelief]], and the comic video, [[https://www.youtube.com/watch?v=Et2rvbpPx_w Papyrus no longer believes in you]], while the other comes from the comic video itself.[[/labelnote]]

** [[spoiler:Mettaton NEO is infamous for being a literal ZeroEffortBoss despite [[AnticlimaxBoss looking awesome and having a badass buildup]].]] Many [=YouTube=] videos and Vines exist dedicated to mocking how ridiculously easy the battle is. Or, alternatively, to try to give him an opportunity to shine and to [[AdaptationalBadass be a badass]].
*** Some have joked that [[spoiler:NEO]] stands for [[spoiler:[[FunWithAcronyms Non-Effective Obstacle]].]] However, this joke is dead as of Chapter 2 of ''VideoGame/{{Deltarune}}'', whose [[spoiler:secret boss, Spamton NEO]], not only is the strongest boss in the chapter, [[spoiler:but he even turns NighInvulnerable in the Weird Route]].

** Comparing [[spoiler:Chara, mainly Genocide Chara]] to [[VideoGame/{{Hatred}} Not Important]].[[labelnote:Explanation]]They both want to kill everyone, if for wildly different reasons. Also may have to do with how he proclaims "[[HilariousInHindsight My genocide crusade begins here]]" in the teaser trailer for the game.[[/labelnote]]

* "Dogsong" in general, due to its wackiness. Thanks to it being used in places like [[spoiler:the "Spare Sans" NonStandardGameOver and the Hard Mode ending]], and its connection to the [[AuthorAvatar Annoying Dog]], it's become associated with Toby Fox being a huge {{Troll}}, and trolling in general.
