* In ''[[{{Fanfic/AceCombatTheEquestrianWar}} Ace Combat: The Equestrian War]]'', [[{{TheLeader}} Firefly]] does two F-Strikes, both being aimed at [[{{TheHeroine}} Rainbow Dash]]. There are different reasons for it, however.
** In chapter 12, while Rainbow is suffering from a HeroicBSOD:
-->'''Firefly''': You know what? TO [[{{HoldYourHippogriffs}} HAY]] WITH YOU!
** In chapter 16, when Rainbow tries to calm her down:
-->'''Firefly''': I CANT CALM THE BUCK DOWN!
** In chapter 19, she does it for the third time, this time aiming it at [[spoiler: Black Star]]:
-->'''Firefly''': I DON'T GIVE A FLYING FEATHER ABOUT YOUR ORDERS!
* Of all people, Nia calls Yoko a "bitch" in ''FanFic/TengenToppaGurrenSolvernia''. [[spoiler:Because of a LoveTriangle, and the fact that Kamina had died, Nia was completely [[BreakTheCutie broken]] and then Kiyal [[IdiotBall thought]] it would be a good idea to have them talk about their feelings, that they could support each other. Things went from bad to worse, really worse. But, after their discussion, both Nia and Yoko are totally remorseful of it.]]
* FanFic/AGrowingAffection is over 650K words long and uses 'shit' exactly five time (the 'F' word does not appear at all).
** 1) Anko says 'Oh shit' in surprise when Naruto and Hinata walk into the restaurant where she and Iruka are having dinner (their relationship is supposed to be a secret from Naruto).
** 2) Kankuro's only thought is 'Oh shit' when his team is attack by the unleashed One-Tail.
** 3) Naruto says 'Holy shit, Hinata!' when she suddenly and unexpectedly strips down to some very sexy lingerie.
** 4) Kayo of the Grass promises to round up 'everyone who isn't a traitor or too chicken-shit to help'.
** 5) A random grey Shozoku proclaims 'Shit' when realizing her squad has fallen into the heroes' trap.
* ''Fanfic/AddressUnknown'' has Rainbow Dash's exclamation of "''Bastard!"'', after learning how Derpy's previous boss put her on probation and then fired her at the first opportunity, over an accident that was actually Twilight's fault. She follows it up with an [[NarrativeProfanityFilter undescribed]] ClusterFBomb.
* The ''Manga/RanmaOneHalf''/''WesternAnimation/TeenTitans'' crossover duology ''FanFic/DarkTitans'' uses a PrecisionFStrike as a CrowningMomentOfAwesome; near the end of ''The Titans and the Lost Boy'', [[BigBad Brother Blood]] has a laser blade to Kasumi's neck, and has ordered the Nerima Wrecking Crew and his rebellious students -- including some of the Nerima regulars, themselves recruited earlier in the story -- to [[HostageSituation kill the Titans or else]]. Both sides appear to be hopelessly stuck... until Kasumi quietly calls Blood... ''[[TWordEuphemism something]]''... and shocks him so badly that she's able to break his grip and [[WaifFu judo throw him]].
* ''MyImmortal'': "WHAT THE HELL ARE YOU DOING YOU MOTHERFUKERS!" Shocking because it's the ''Dumbeldore's'' IncomingHam moment.
* ''[[Fanfic/TiberiumWars Yea verily, though I charge through the valley of the shadow of death, I shall fear no evil, for I am driving a]] [[TankGoodness house-sized mass]] [[SophisticatedAsHell of "fuck you."]]''
* [[http://www.fanfiction.net/s/5145477/1/Deaths_Redemption "Look me in the eyes, Light damn you!"]]
* [[http://tvtropes.org/pmwiki/pmwiki.php/FanFic/MegaManAtMcDonalds Mega Man At McDonalds]]: in the first chapter, Proto Man sees Mega Man accidentally kill one of his coworkers with volcano sauce (Made with actual lava) and yells "HOLY SHIT WHAT HAVE YOU DONE?"
** "YOU SMEGMA CONE CUNTCHILD!"
* Pulled off to great effect by [[ShrinkingViolet Hinata]] in [[http://www.fanfiction.net/s/2731239/8/Team_8 Team 8]]: "That's bullshit!" ''([[{{Beat}} pause]], [[DidIJustSayThatOutLoud slaps hands over mouth]])''
* [[FanFic/PrettyCurePerfumePreppy "DON'T CALL ME PIT, DAMMIT!"]]
* ''Fanfic/FinishingTheFight'' [[spoiler: MC vs Matron Baenre. During the assault on Mithril Hall, Baenre Teleports out. The MC's response? "Shit!"]]
* ''Fanfic/ThoseLackingSpines'', about entering Voreland: "ABSOLUTELY FUCKING NOT!"
** There's also chapter 12, when the [[spoiler: Grand Master Fangirl's]] evil plan has finally been revealed, and we get this:
-->"Well, now what?" Lexaeus sighed.\\
"It would seem we are" Vexen murmured.\\
"Lost for options?" Xaldin suggested.\\
"In a tight spot?" Lexaeus added.\\
"Between a rock in a hard place?"\\
"In hot water?"\\
"Verily fucked," Vexen answered.\\
"Ah."
* If you can get the Roleplay/DCNation universe version of [[GreenArrow Connor Hawke]] to the point of swear words, it's usually one of those.
* For the most part, the Shocker fan fic [[http://www.fanfiction.net/s/5124106/1/Polarity Polarity]] avoids any swearing worse than "damn" or "crap." Even after fighting zombies, avoiding heroes, brawling with villains, and getting his ass handed to him night in and night out, Herman Schultz and company keep the language tame...until [[spoiler: Big Bad the Grim Reaper shows Shocker what happened to the last guy who turned him down, revealing the Punisher trussed up like a stuck pig slowly being bled to death.]]
--> After my jaw dropped for a few seconds, I decided it was time to sum up this entire situation in a very simple and succinct phase. "You're fucking nuts."
* In ''FanFic/PrettyCureHeavyMetal'' episode 24, Shugo fakes an Australian accent and lands a [[NWordPrivileges precision N strike]] in a parody of the N word privileges supposedly held by white Australians. The rest of the N words are spoken by the [[TokenMinority token black]], who has all the N words in episode 25.
** Later, in episode 51, Shugo drops an uncensored F bomb right before [[spoiler:she dies from her wounds]], just to maximize the impact. [[spoiler:She gets better.]]
* In FanFic/KiraIsJustice: "Oh crap." Bear in mind that the author almost never uses any curse words in his writing. Not even "stupid".
* In Fanfic/RelationshipsSeries story "Pain", Shamal asks "what the hell happened" to a badly injured Yuuno. Vita notices that this is the only time she has heard Shamal swear.
* Takeru Takaishi from the ''FanFic/TamersForeverSeries'' delivers one of these:
-->''"Do you understand now? We're not going to a fucking walk in the park. This is not a goddamned picnic."''
* ''FanFic/ElementalChessTrilogy'': "You leave my family alone, you cowardly son of a bitch!" It's a CrowningMomentOfAwesome for the speaker, and an odd sort of CrowningMomentOfHeartwarming since the "family" in question are the speaker's TrueCompanions. It's also the only time in the entire series that anyone uses a swear word other than "damn."
* ''Literature/HarryPotter'': Draco nails this trope in ''[[http://www.fanfiction.net/s/7093944/1/Yea_Though_I_Walk Yea, Though I Walk]]'' when he [[spoiler: explains to Hermione, that killing Snape won't stop the demon that is claiming the Death Eaters from possessing his body]] The cursing and Draco's grief due to [[spoiler: [[MercyKill mercy killing]] his possessed father in vain, and her mother sacrificing herself to the demon to save her son]] really highlight that the situation seems completely hopeless.
--> '''Draco''': You can't kill a fucking demon with a pillow!
** In another ''Literature/HarryPotter'' fan fic straight-laced Percy realizes that [[spoiler: the Minister of Magic is under the Imperius curse, which could only mean Voldemort is controlling him]]. His mental response: "Oh, ''shit''."
* ''FanFic/TheGift'': While other characters seem not to mind colorful language, [=JoJo=]...''doesn't''. Except when the [[{{AI}} invisible hologram]] explains that she's part of a [[QuantumLeap time experiment gone awry]], she combines it with a spoonerism:
--> '''[=JoJo=]''': "What the ''talk'' are you fucking about?"
* In ''FanFic/HogyokuExMachina'', after being told by [[Manga/{{Bleach}} Ichigo]] ([[TimeTravel who has]] [[PeggySue traveled from]] [[HaveWeMetYet the future]]) that his plan to [[spoiler: take down the BigBad by acting as a mole and assassinating him will ultimately not work]], Gin's eyes are [[EyesAlwaysShut wide open]] and he says, Well....shit.
* In the fifth chapter of [[http://www.fanfiction.net/s/7436420/1/Pocky_in_Ramen this]] ''Manga/DeathNote'' fanfic, Mello finds out that [[BrilliantButLazy Matt]] scored ''a lot'' higher than he'd assumed. It turnes out [[spoiler:the two of them made a SideBet, with Mello assuming that he'd win. Well it turns out things didn't go that way...]]
-->'''Matt''': I'm getting a codename.
-->'''Mello''': [[OhCrap You're kidding me]]
-->'''Matt''': Nope
-->'''Mello''': [[ThisIsGonnaSuck So that means...]]
-->'''Matt''': That means [[HalloweenCosplay for Halloween]], [[DraggedIntoDrag you're going as]] [[SuperMarioBros Peach]].
-->'''Mello''': Shit.
* ''WebAnimation/TurnaboutStorm'':
** [[Franchise/AceAttorney Phoenix]] drops a pair of "Dammit"s through the story. It doesn't go unnoticed.
-->'''Phoenix:''' Dammit! She knows!\\
'''[[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight]]:''' Phoenix! Language!
** Gilda drops a few "Damn"s in her interrogation out of anger (which makes Twilight DeathGlare ''Phoenix'' [[ButtMonkey for some reason]]). She also leaves out a "Crap", but given the circumstances, no one calls her out on it.
* The normally unflappable Prowl has a couple of these in ''[[FanFic/ThingsWeDontTellHumans Things We Don't Tell Humans]]'', one as a child, establishing his intense dislike of Sentinel Prime, and another when [[RenownedSelectiveMentor Terratron]] allows his students to gather together in public.
* ''Fanfic/MassEffectInterregnum'':
-->'''Garrus:''' I don't say this often, so understand that I really, really mean it: go fuck yourself.
* The first sentence of [[http://www.fanfiction.net/s/4245303/7/ Chapter seven]] (or six, not counting the prologue) of FanFic/KOTORTheProdigyOfRevanBookOne ends with Carth noting [[ProudWarriorRaceGuy Jack's]] mood isn't the most [[UnstoppableRage ...civil.]]
** Considering the whole [[spoiler: Zalbaar-being-captured-by-Gamorean-slavers]] circumstance, it's understandable
* In ''FanFic/PrettyCureHollywoodStars'', Lina gets a Precision Black Strike, and because she's white it is ''NOT'' the N word (it's been stated numerous times in-story that she isn't racist, though she does drop an epiphet from time to time and gets called on it by either one of the other characters or the [[AuthorAvatar narrator]]). Here's a hint: think [[GranTorino Clint]], for whom the author named her.
* In {{Fanfic/Reconciliation}}, this happens at two different points in a single chapter, as Lilly [[spoiler:is undergoing an emotional breakdown after her husband Hisao's funeral]].
-->'''Akira''': "Help me to understand here, Lilly, because right now Im getting really fucking scared. Ive never seen you like-
-->'''Lilly''': Thats bullshit. [[spoiler:My husband is dead. Hes dead, Hanako, and hes not coming back]].

* Talking of Gurren Lagann fics, Nia also gives a PrecisionFStrike in ''[[http://www.fanfiction.net/s/4138412/1/Sound_of_Pulling_Heaven_Down Sound Of Heaven Pulling Down]]'', during a discussion, but she doesn't seem to be aware of the meaning of the word "fuck". Simon even lampshades it, saying he won't swear next to her anymore.
* ''FanFic/TheStarsWillAidTheirEscape'' has one from Applejack, aimed at [[BigBad Herald]], after the latter has [[spoiler: [[SealedGoodInACan banished the Princesses]]]]:
-->"What did you do [[spoiler: to the Princesses]] you bucking son-of-a-bitch!?"
* In ''StreetSharks Redux'', Bends mentally gives a "fuck" when he realizes that [[MadScientist Paradigm]] likely saw a note he left, proving that he had been in contact with the Boltons after they were experimented on.
* Used in ''{{Fanfic/Human Curiosity}}'', after [[spoiler:Italy, Japan, and Canada regain their memories and find the other free nations.]]
--> "Sir, we can faintly detect [[spoiler:North Italy, Japan and Canada]]!"
--> "Where are they?"
--> "... Oh shit."
--> "Sir, we do not tolerate such language in this-"
--> "Sir, they're [[spoiler: with America, Germany, Spain and South Italy in the USA, a couple miles away from Canadian borders.]]"
--> "Shit."
* ''[[http://www.fanfiction.net/s/8514012/2/Keena-the-Defendants-of-Constan-Magic-Academy Keena & the Defendants of Constan Magic Academy]]'' has ''two'' from Keena herself to Mr. X in chapter 2:
--> '''Keena''': FUCK! YOU! [[ContinuityNod You almost attempted to molest me and I never even bothered to fight back somehow! Kurone should have punched through your goddamn brain and left you for dead!]] Those are my two cents of you, mister!
* "Christ, what an asshole!" in ''FanFic/WhoSilencedEllyPatterson''. Surprising in that it's ''Anthony'', the rather bland CreatorsPet from ''ForBetterOrForWorse'' who said it.
* [[http://www.fanfiction.net/s/7832146/1/Swapping-The-Cage Kuushou]] aka Kyuubi doesn't necessarily shy away from cursing. However, one occasion that really stands out is when he learns that virtually every ninja skill (including chakra control exercises) is considered advanced training, and thus not taught until after graduation.
--> '''Kuushou''': "For fuck's sake! How in Kami's name did you let those kids graduate?"
* Three in ''Fanfic/PerfectionIsOverrated''
** When [[MaiHime Mai]] encounters Nao in the hospital, learns about her comatose mother, the incident that led to that, and that Nao had to let that incident happen to avert a temporal paradox, she offers her condolences, but Nao, embittered and thinking of most people's expressions of sympathy as being empty and insincere, shoots back with "You're ''fucking sorry''?".
** Natsuki utters OhCrap verbatim when she suffers a PsychosomaticSuperPowerOutage that leaves her defenseless when [[spoiler:Yukariko reveals that she has betrayed the Himes]].
** Mai, when faced with a last ditch attempt by the BigBad at convincing her to accept his plan.
-->'''Mai''': "[[ShutUpKirk To hell with your new world that is only perfect for you! We'll decide our own future]]!"
* In ''Fanfic/LillyEpilogueFamilyMatters''
** After Hisao learns that Lilly's parents are coming, and fears they might force her to come home.
-->'''Hisao''': [[OhCrap Oh fuck]].
** After Lilly's father decides to KickTheDog by ''deliberately'' insulting Hanako's burn scars and ShrinkingViolet nature.
-->'''Akira''': I can't believe that asshole!
** Even Lilly gets in on this, after [[spoiler:her father insulting her best friend and her boyfriend pushes her over the edge and she, for the first time, calls him out for leaving her in Japan for six years]].
-->'''Lilly''': [[spoiler:[[CallingTheOldManOut YOU HARDLY RAISED ME AT ALL, YOU BASTARD]]!!]]
* After 18 chapters of nothing worse than "damn", "hell" and "arsehole" in ''Fanfic/WarriorsOfTheWorld'', the character most likely to swear calls someone else a "little shit". This turns out to be an OOCIsSeriousBusiness moment, as he only swears that severely when he's trying not to resort to violence or anger.
* Earl Flatbroke in the ''Fanfic/EmpathTheLuckiestSmurf'' adaptation of ''WesternAnimation/TheSmurfsAndTheMagicFlute'' delivers one: "I don't give a flying fig for what they'll say."
* A relatively mild one from ''Fanfic/CanYouImagineThat'' (do keep in mind that it imitates a children's movie):
--> '''Worker:''' [[ItMakesSenseInContext Why do [the kids] need a milkshake?]]\\
'''Retro:''' How the hell should ''I'' know?
** Also leads to a {{narm}}y moment when Retro later yells "YOU SKANKS!"
* In the ''FanFic/PonyPOVSeries'', during the FinalBattle between Shining Armor and [[GeneralRipper General-Admiral Makarov]] (the BigBad of his arc), Makarov wants the captive Shining to say "I surrender, Solomon". What he gets is "[[DefiantToTheEnd Go fuck yourself]]" (and actually the f-word, not the pony substitute word "buck", as Makarov is a male half-deer).
* In ''Fanfic/SakiAfterStory'', while there is a fair amount of profanity, Sumire's screaming "WHAT THE FUCK IS WRONG WITH YOU?" when finding Teru beating up her younger sister Saki (as well as Nodoka when she tries to help).
* Coupled with OOCIsSeriousBusiness in ''Fanfic/TheNextFrontier''. [[TheStoic Bill's]] startled yell of "Holy shit!" immediately alerts Jeb to the fact that something major is going down.
* In ''[[http://web.archive.org/web/20011030045917/http://www.fortunecity.com/lavendar/pimlico/131/monster.html Monster Movie]]'', when [[MysteryScienceTheater3000 Crow]] tries to contact Joel after [[spoiler:Joel's caught by the shadow-thing that the SOL picked up]], [[OOCIsSeriousBusiness Joel]] tells Crow to "Shut the fuck up and leave me alone!" This horrifies Crow because Joel would never say that to him.
* In ''FanFic/MegaManDefenderOfTheHumanRace'', [=ProtoMan=] drops the fic's single f-bomb upon seeing Dark Man 2.
* In ''Fanfic/BleachFanWorks'', Jolene Meyers, an in-universe fanfic writer, does this [[DearNegativeReader in response to a fictional reviewer]].
-->'''Jolene Meyers''': If you don't like my character, then fucking don't read.
* ''Fanfic/{{Bait and Switch|STO}}'':
** In chapter three, when Gaarra manages to corner Eleya in the USS ''Bajor''[='s=] officers' gym after she spent the first three days of the voyage avoiding him ([[IntroductionByHookup they'd had a one night stand before she found out he was her new ops officer]]). The tricky bit is, since the two of them are actually speaking Bajoran dubbed as English, it's also a combination of PardonMyKlingon and TranslationConvention.
--> '''Gaarra:''' Well, look at it this way: You think it's any easier for me? You fucked your ops officer, ''I'' fucked ''my'' commanding officer.
** In the {{prequel}} "Fanfic/TheUniverseDoesntCheat":
*** From Commander Hackett after Eleya rams her way past the initial encounter with the Klingons.
--->"Holy ''shit''! Did you see that?!"
*** Eleya is a SirSwearsALot, but she still has an example by swearing in English instead of Bajoran as is more usual for her. This is after Captain Sivuk asks her opinion on no-win scenarios.
--->"Oh, I believe in no-win scenarios. I also believe they mostly take place because somebody ''fucked up''!"
* Valkron in ''Fanfic/WarriorsOfTheWorldSoldiersOfFortune'' never swears any worse than "hell" or "damn" throughout the entire story despite what happens. Which makes this one quite effective.
--> "Look here, you little ''shit''."
