!!The first film:
* AcceptableTargets: The popular girls, hoo boy. Especially blondes.
* AlternativeCharacterInterpretation: Back when Janis and Regina were friends, Janis was the [[AlphaBitch queen bee]] and Regina was the innocent friend (like Cady) who was [[FromNobodyToNightmare slowly evolving]].
%%* CultClassic
* DesignatedHero: Janis. She is just as manipulative as Regina, taunts her by revealing her manipulations in front of the entire school (throwing Cady under the bus in the process), [[MoralDissonance and gets cheered for it]]. This, combined with her HollywoodHomely appearance, has only fueled some fans' theories that Janis is herself a [[FallenPrincess former]] AlphaBitch.
* EnsembleDarkhorse: Special mention has to go to Glen Coco. To put this in perspective, he appears on screen for about 4 seconds, the only part of him shown is the back of his head, he does not speak, and we only hear a single line about him:
--> Glen Coco? Four for you Glen Coco! You go Glen Coco!
** According to the special features, the Mathletes were the favorite characters of the cast and crew.
%%* FountainOfMemes: Karen.
* GeniusBonus: The whole "We should kill Caesar" speech may just be a history report, but when taken out-of-context it sounds like something an actual Roman senator would say about Creator/JuliusCaesar.
* GirlShowGhetto: Subverted. It's still generally considered a "girls' movie," but it's gotten a generous amount of positive word-of-mouth from men who were pleasantly surprised by it.
* HilariousInHindsight:
** Regina's "I couldn't have a lesbian at my party..." took on a whole new (and funny) meaning when Creator/LindsayLohan picked up a girlfriend, and now that Creator/AmandaSeyfried has done [[Film/JennifersBody two]] [[Film/{{Chloe}} movies]] in which her character [[GirlOnGirlIsHot makes out (and in one case, has sex) with another woman]].
*** For an added bonus, take a look at the list of songs during the credits. One of them is performed by Samantha Ronson, Lohan's on-and-off girlfriend.
** The fact that the film was toned down to PG-13 after Lindsay Lohan was cast, due to her being too "family-friendly" to star in an R-rated film.
** And that Lohan considered that starring in the film as a "mean girl" would hurt her rep.
** Before playing Gretchen Wieners, Creator/LaceyChabert was the voice of [[WesternAnimation/TheWildThornberrys Eliza Thornberry]], who traveled around exotic lands with her parents like Cady.
** Though it also counts as a HarsherInHindsight depending on your view, the movie follows [[Creator/LindsayLohan Cady]] as she falls in with the wrong crowd and goes from a mild-mannered nice girl into a party-happy temperamental bitch. Lohan's constant arrests and trips to rehab afterwards have led to the [[MemeticMutation widespread idea]] that Regina got the last laugh on Cady in the end.
** Cady sees two girls making out at the Halloween party and looks very dismayed.
** [[http://static.tvtropes.org/pmwiki/pub/images/mean_girls_xl_05--film-A.jpg This shot]] has become surprisingly prophetic. [[note]]Yes, that is Lohan in the garbage bin.[[/note]]
** Neil Flynn, who at the time was best known for his then-current role as the Janitor from ''Series/{{Scrubs}}'', plays a father so clueless and passive as to come off as almost purposely apathetic -- which also very closely describes Mike Heck, Flynn's current role in ''Series/TheMiddle''.
** At the end, [[spoiler:Regina channels her rage into sports, specifically field hockey]]. At the climax of ''Film/RedEye'', Creator/RachelMcAdams's character goes to town on the villain with a hockey stick. Also, the high school photo of Lisa playing hockey in ''Red Eye'' is a screenshot from this movie.
** Daniel Franzese (Damian) [[http://www.advocate.com/arts-entertainment/2014/04/22/mean-girls-actor-daniel-franzese-comes-out really is too gay to function]].
** The fact that Lindsay Lohan was the only actress to go under the knife, in a movie that labels the ''villains'' as "plastic".
** If one watches season 6 of ''Series/PartyOfFive'', Lacey Chabert's character plays a Cady-type character to a Regina type (though this one is more of a LovableAlphaBitch).
** Damian asking Cady to talk about Creator/AshtonKutcher, considering that his name later appeared in Lindsay's infamous list of lovers.
** Let's see... Creator/RachelMcAdams (Regina) and especially Creator/AmandaSeyfried are both still very successful actresses, and Creator/LindsayLohan (Cady) is still famous (or maybe just infamous) due to her presence in the tabloids. As for Creator/LaceyChabert... "And none for Gretchen Wieners, bye!"
** Regina's little sister, seen shaking her ass to trashy pop music at [[TroublingUnchildlikeBehavior way too young an age]], is named Kylie, sharing her name with [[http://en.wikipedia.org/wiki/Kylie_Jenner another rich girl]] who, ten years later, would herself become famous for wearing skimpy clothes and dating rappers at [[JailBait way too young an age]]. The ages even line up: Nicole Crimi, the girl who played little Kylie in ''Mean Girls'', was born in 1996, just one year before Kylie Jenner.
* HollywoodHomely:
** Lizzy Caplan as Janis Ian. Anybody who's seen her in anything else she's done (especially ''Series/TrueBlood'' and ''Series/MastersOfSex'') knows that she is drop-dead gorgeous in real life. In fact, she almost didn't get the part, as the casting director [[AbilityOverAppearance thought she was too pretty at first]]. As such the costume designers deliberately gave her an alternative/goth type look, rather than trying to dress her down. Caplan's beauty is probably a contributing factor to the theory that Janis is a former Queen Bee.
** Averted with Gretchen, who was originally written as a much homelier character who was only popular because she was rich. This was changed when Lacey Chabert was cast in the role, and while the occasional line to this effect still shows up, it can easily be written off more as cattiness than her actually being viewed as unattractive.
* HollywoodPudgy: Regina's weight gain is almost entirely informed. Wardrobe allegedly stuffed Rachel McAdams' sweatpants and gave her an oversized hoodie to give her the appearance of having gained weight...but her upper half is swimming in the hoodie, and the pants only appear to be a trifle snug.
* LGBTFanbase: Ridiculously popular among both gay men and women, and is something of a modern faux-camp classic.
* MagnificentBitch: Janis Ian, and Regina George herself once she catches on to the scheme against her.
* MemeticBadass: He doesn't get any lines, but he still gets a lot of play on the internet, "Four for you Glen Coco! You go Glen Coco!"
** Also Regina George for the "How do I begin to explain Regina George?" meme, which makes her something of an in-universe example.
* MemeticMutation: On Website/{{Facebook}} and Website/{{Tumblr}} (''especially'' Tumblr), there is not a single line from this movie that is not memetastic. Seriously, it's too many to count. [[Memes/MeanGirls So we made a page for it.]]
* MisaimedFandom: Oddly, this movie seems to be most popular with the same kinds of people that it mercilessly makes fun of.
** And with PeripheryDemographic: This movie is popular with a lot of guys, particularly those who had a thing for Lohan back in the day and are nostalgic for her pre-trainwreck career or are fans of [=McAdams=], Seyfried or Chabert curious about their early careers. Also heavily related to TestosteroneBrigade listed below.
** People that work with teenage girls, such as middle/high school faculty, find this movie very comical and a little too close to home.
*** And even a few SNL aficionados by way of Fey. ''Still'' very much related to Testosterone Brigade in this case.
* {{Narm}}: Janis's TitleDrop "You're a mean girl!" can come off as this, considering most of her vocabulary is composed of nothing but profanity.
* OlderThanTheyThink: The often quoted line "It's like you've got ESPN or something" is a [[{{Malaproper}} malapropism]] probably almost as old as the channel itself.
* PopularityPolynomial: Mean Girls was moderately successful when it first came out before fading into obscurity. Its popularity suddenly exploded in TheNewTens into [[MemeticMutation one of the most quoted movies ever.]]
* RetroactiveRecognition: The jock Shane Oman is played by Diego Klattenhoff, who currently has a main cast role as FBI Agent Donald Ressler in ''Series/TheBlacklist''.
* TestosteroneBrigade: While written by [[Creator/TinaFey a woman]] and marketed heavily to teen girls, it was released at the height of Creator/LindsayLohan's [[HollywoodHypeMachine "it girl"]] popularity, and features Lohan and a number of other young women in provocative dress throughout. Lots of men went to see it for the hot high school chicks.
** Creator/BellaThorne, when promoting ''Film/TheDuff'' on Creator/TheBBC's Radio 1, invoked this when trying to persuade the DJ's producer (a man) to see ''Mean Girls''[[note]]that's right, she was promoting a different movie - luckily Paramount and CBS Films, which made ''The DUFF'', are part of the same corporate family[[/note]], pointing out its brilliance and adding "Plus it's [[Creator/LindsayLohan got]] [[Creator/RachelMcAdams four]] [[Creator/LaceyChabert hot]] [[Creator/AmandaSeyfried girls]]."
----

!!The sequel:
* FirstInstallmentWins: Fans of the original generally consider the sequel to be unnecessary and inferior to its predecessor.
* FunnyAneurysmMoment: It's mentioned Tyler goes to Penn State in the epilogue. It's not the best school after the Sandusky scandal.
* InformedWrongness: What Jo did to Hope is pretty bad, but her tattling on Chastity for making out on school property is treated the same, even it is against school rules.
* ReplacementScrappy: Obviously, Mandi is no Regina George.
* {{Sequelitis}}: Apart from the element of Jo creating a group of Anti-Plastics and the climactic football game, the film is pretty much a remake of the first film, without the laughs. Also Jo's friends turning against her is extremely forced.
** Tina Fey repeatedly turned down offers to make the sequel. Now that the sequel was done without her, she regrets turning down the offer.
* UnintentionallySympathetic: Mandi's step-brother is ''really'' callous towards her. It's not exactly undeserved but since she seems to like him, Taylor can come across as a bit of a jerk and arguably even as a contributing factor to Mandi's bitchiness.
