!!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]].
* BetterByADifferentName: Inverted by WebVideo/TheNostalgiaChick, who said that this film was a remake of ''Film/TheCraft'', only PlayedForLaughs, without the witchcraft, and a better film for it.
* CultClassic
* DesignatedHero: Janis. She is just as manipulative as Regina, taunts her by revealing her manipulations in front of the entire school, [[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: A highly quotable movie, a lot of the lines from it have taken on their own meaning and get quoted frequently.
** Karen in particular.
* FridgeBrilliance: Regina's line referring to Gretchen's nomination for Spring Fling Queen, saying that "She's not even pretty." In the original script, Gretchen was intended to be average at best, ugly at worst - mostly desirable because of her expensive clothes and lavish lifestyle. When the obviously pretty Lacey Chabert was cast for the role, this line was left in, and rather than just a statement, it becomes an insight into Regina's character. She truly believes that she is the queen bee because she deserves it, because she is superior to Karen and Gretchen. YMMV on which girl is most attractive, but fans can all agree that each of them is gorgeous, and only Regina's inflated ego could have resulted in such a surprise at Gretchen's nomination.
* 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 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 [[TheWildThornberrys Eliza Thornberry]], who traveled around exotic lands with her parents like Cady.
** Though it also counts as a FunnyAneurysmMoment depending on your view, the movie follows [[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]]
** From the sequel, Jo, the protagonist who is mercilessly tormented by the AlphaBitch, is portrayed by Meaghan Jette Martin, who [[CampRock would later go on to play an Alpha Bitch herself.]]
** 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.]] 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).
* 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.
* LGBTFanbase: Ridiculously popular among both gay men and women, and is something of a modern faux-camp classic.
* MagnificentBitch: Janis Ian. Regina George herself has her moments too.
* 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!"
* MemeticMutation, FountainOfMemes: 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.
* 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.]]
* SomeAnvilsNeedToBeDropped: Saying hurtful things about others, directly or indirectly, is extremely painful to everyone.
-->'''Cady:''' Calling somebody else fat won't make you any skinnier. Calling someone stupid doesn't make you any smarter. And ruining Regina George's life definitely didn't make me any happier. All you can do in life is try to solve the problem in front of you.
** Another very wise line from Ms Norbery: "You have ''got'' to stop calling each other 'sluts' and 'whores'. It only makes it easier for [[SlutShaming guys to]] [[MyGirlIsNotASlut call you]] [[MadonnaWhoreComplex sluts and whores]]."
* 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 TheBBC's Radio 1, invoked this when trying to persuade the DJ's producer (a man) to see ''Mean Girls'', pointing out its brilliance and adding "Plus it's [[Creator/LindsayLohan got]] [[Creator/RachelMcAdams four]] [[Creator/LaceyChabert hot]] [[Creator/AmandaSeyfried girls]]."
* WhatCouldHaveBeen: [[http://bust.com/mean-girls-10th-anniversary-reunion-cast-spills-secrets.html In an article for "Entertainment Weekly"]], the actresses were asked about what they imagined their characters as and TinaFey regretted not writing a sequel.
---> ''Karen:'' Manage or own a store that sells really cool dog attire, like Swarovski dog collars and Halloween costumes for animals.
---> ''Cady:'' In Africa with [[OprahWinfrey Oprah]] working at children’s schools with family, teaching girls to be nice.
---> ''Gretchen:'' Running the Toaster Strudel Empire. She has curly hair and worked everything out with Jason.
---> ''Regina:'' She’s a [[TheRealHousewives Real Housewife]] and has found all her other Reginas.

!!The sequel:
* ContestedSequel: 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.
* JerkSue: Jo.
* 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.
