* AlternativeCharacterInterpretation: Are Kaorin's feelings towards Sakaki really SingleTargetSexuality like she claims or is she just [[{{Gayngst}} in denial about being gay]]?
%%* AwesomeEgo: Tomo and Kagura
* SugarWiki/AwesomeMusic: The opening and closing themes, as well as many of the image songs. In particular, Kagura's "Ashita wa Makenai! GO! FRIEND!" and Sakaki's "Kokoro wa Shoujo de PARACHUTE".
* BaseBreaker: Depending on who you ask, Tomo is either considered to be one of the funniest or one of the most annoying characters in the series.
%%* CrazyAwesome: Osaka, Kimura and Chiyo-chichi
* DudeNotFunny:
** Some of Tomo's pranks on Chiyo and Osaka can fall under this.
** Along with Yomi coercing Osaka into eating spicy food that Osaka ''specifically says she doesn't like to eat'', and then doing nothing to help the resulting hiccups.
*** The manga version of this has Kagura fill Tomo's role of trying to beat the hiccups out of Osaka, and that time ''it actually really looked like it hurt'' and unlike Tomo, ''Kagura doesn't apologize.''
* EarWorm:
** If you can listen to ''Soramimi Cake'' (aka "{{Mondegreen}} Cake") without it getting it stuck in your head, you are officially immune to any EarWorm.
** Also, there's ''E'ye'' or ''E'ye 2''; the songs used for the eye-catchers during the commercial breaks? If that tune doesn't turn into a ringtone for your cell phone, then you officially are deaf to any and all EarWorm.
%%* EnsembleDarkhorse: Chiyo-chichi and Kimura-sensei.
* FountainOfMemes: Judging by the videos out there, [[http://wiki.ytmnd.com/Osaka Osaka had this going for her from the start.]]
* FunnyAneurysmMoment: There's a joke in the supplementary lessons about Osaka thinking it will be a good day because she woke up early, only for an earthquake to rock the school a moment later. By the way, the school is in Tokyo.
* IronWoobie: No matter how hard the world tramples on her, Sakaki never gives up trying to be a good person.
* JerkassWoobie: [[AlternateCharacterInterpretation If her dreams are any indication]], [[InferioritySuperiorityComplex Tomo has massive insecurities, which leads to her]] being such a {{Jerkass}}.
* MarySue: A complicated case with Sakaki: she's tall, beautiful and athletic, intelligent and educated, is kind and polite and has a wonderful singing voice and may or may not be rich. Except she doesn't want any of this, she just wants to be small and cute and tend to cats, but all cats everywhere [[spoiler: well, mostly anyway]] seem to instinctively attack her viciously. And the wounds she gets from those attacks, combined with her calm demeanor and her physical size make her seem to other students more like a scary delinquent than anything. Or, in case they don't think she's a delinquent, they admire her beauty and athleticism from afar and never approach her.
* MemeticBadass: [[http://mastafuu.deviantart.com/art/Hunted-Predator-20292897 That little moment with the knife gets stuck in peoples' heads...]]
%%* MemeticMolester: Osaka and Kimura.
* MemeticMutation:
** "Mai waifu", as first spoken by Kimura when introducing his [[UglyGuyHotWife hot]] "waifu" to the girls. Used by fans to describe anime or video game women that are, in their opinion, "desirable". Also, [[NightmareFuelStationAttendant Osaka is evil]].
** OH MY GAH!
** The Caipirinha meme originates from video of Tomo's taunting dance of Chiyo from episode 20 set to "Capirinha", a song about Brazil's national drink.
** Let's not forget Osaka's weather prediction.
** For some reason, Yomi has become the mascot for various image boards' "war on [[AcceptableTargets furries]]". It has to be from the episode with Tomo in the mascot outfit.
** A text drawing of Osaka was used in a [[http://c64.org/~jgb/osakaphone.swf short viral flash video]], set to a sped-up version of Raffi's "Bananaphone". Later became the mascot for AMVHell, after being used in a [[http://www.youtube.com/watch?v=ceV9K0zxd_s parody of the infamous Ellen Feiss Apple commercial]].
** Rachel Handelbarz goes great with mustard.
** [[InherentlyFunnyWords Sata Andagi! Sata Andagi!]] [[OverlyLongGag Sata Andagi! Sata Andagi!]]
** [[http://www.qqdaxia.com/qiandaibaba.html The Chiyo-dad emoticons]], also known as the "dead cats".
** [[GratuitousEnglish And of course]]; '''"HARRO EVERYNYAN!"'''
* MemeticPsychopath
** Osaka after the "Wake Up Frying Pan Fiasco."
** Yomi, mainly when it relates to furries.
* {{Moe}}: The series itself is something you can curl up with, but Chiyo-chan is Moe to the ''n''th degree (''[[UpToEleven especially]]'' [[UpToEleven when she's in the penguin suit]]), and Osaka and Kaorin are also incredibly cute. Osaka may actually be at least partially responsible for the popularization of the concept, placing second in the 2002 Saimoe Tournament. Hell, this series is sort of [[UrExample proto-moe]] itself. It [[TropeCodifier codified]] a lot of tropes related to the "genre".
* MostAnnoyingSound: In Tomo's dream. "Nandeyanen?"/"Why in the heck?"
* NeverLiveItDown: Osaka almost stabbing Yukari; Yukari almost didn't live it down either. Which is why, among a few other moments, [[RonTheDeathEater Osaka is frequently portrayed as a cold-blooded killer in some fanworks.]] In canon, she's probably the sweetest and most harmless.
* OneSceneWonder: [[MegaNeko Chiyo's Dad]] shows up in maybe five skits total. Everyone that knows this show will remember him without fail.
* SuperlativeDubbing: While fans give the English dub mixed to positive reviews, most official reviews don't hesitate to compliment the dub cast, and they ''do'' deserve props for getting just about every cultural reference across to Western viewers quite well.
* TastesLikeDiabetes: "Aaa shit, you're so cute!" Yomi says to Chiyo, with an exasperated expression.
* UncannyValley:
** [[http://www.mangatoshokan.com/read/Azumanga-Daioh-Hoshuu-hen/692/1/7 Sakaki doesn't care for the place.]]
** Osaka's unusual manner of thinking combined with her often DissonantSerenity can make her NightmareFuel to some viewers, especially when she has a knife.
* ValuesDissonance: Sakaki's lack of self-esteem, especially when comparing herself to Chiyo, seems downright ludicrous to western viewers who don't understand the difference between Japanese standards of beauty and their own.
* WhatAnIdiot: What was Yomi thinking when she [[http://www.youtube.com/watch?v=6yefMRQFjbU bought bear stew for Sakaki?]] Though it doesn't seem as though she knows too much about what Sakaki is like deep down at that point. [[AlternateCharacterInterpretation Either that or it's another example of her mean sense of humor.]]
* {{Woolseyism}}:
** "Hey y'all, I'm Osaka..."
** Episode 2 has Osaka deliver a pun: "That's not bean knowledge (a Japanese idiom meaning "trivia"), it's knowledge about beans." In the dub, it's changed to "That ain't no grain of truth, that's the truth about grain."
** The omnibus of the manga's English translation changes it to, [[ItMakesSenseInContext "That's not a fun fact, it's a fungus fact."]]
* TheWoobie: Pretty much everyone.
** You may feel sorry for Chiyo after all the abuse she cops from the two resident {{jerkass}}es, and how she sometimes has trouble being taken seriously due to being much younger than her classmates.
** Animals seem to have it in for Sakaki despite the fact that she adores them; her woobieness is rarely so highlighted as the time she lets Kamineko sink its fangs into her hand... and Sakaki doesn't pull her hand away so that she can finally pet him with the other one. Also noteworthy is the attempts Sakaki's friends make to please her. They try to be friendly and warm to her, but unintentionally end up hurting her feelings. Kagura is particularly guilty of this when the two first meet.
** It's hard not to feel for Osaka's inability to stay focused, let alone succeed sometimes.
** Kimura's after Kaorin, much to her despair. You can't NOT feel bad for her, even though it's funny.
