[[caption-width-right:342:Holy crap, look at [[TheStoic that girl]], [[ComicallyMissingThePoint she isn't panicking!]]]]

->'''T-Rex''': Wow! The plants are nice and the birds are singing and the sun is almost down from the top of the sky. What a beautiful day!
->'''Dromiceiomimus:''' But T-Rex, what if beauty is nothing but an illusion? [[DreamApocalypse What if we're all nothing but dreams within dreams that, for an instant, imagine themselves to be real?]]
->'''All:''' OH SHIIIIIIII[[CurseCutShort -]]
-->--''Webcomic/DinosaurComics'', [[http://www.qwantz.com/archive/001457.html "add a few Is every time you do it"]]

Sometimes serious, but often a comedy trope. When faced with something, most or all cast members in the scene ''panic''. Related to CrowdPanic, except it's not about the LivingProp characters. Expect TheStoic or OnlySaneMan to get everyone to shut up for long enough to deal with the problem.

----
!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* In ''Anime/CodeGeass'', Lelouch gives an OhCrap moment to the whole world (that includes some 90% of the cast, too) in the end.
** Of all people, ''Nina'' gives one to dozens of people when she shows up with the Ganymede, packing what is essentially a ''home-built nuke''. The nuke is not actually operational but no one knows that at the time, resulting in [[BunnyEarsLawyer Lloyd Asplund]]'s shrill "'''[[OhCrap IKENAI !!]]'''" when he sees the Ganymede and remembers just what Nina was working on. The second part of this particular Mass Oh Crap comes in the second season when a fully working version goes off... and [[SphereOfDestruction vaporizes a spherical chunk of real estate into thin air]]. Then to hammer it in even further, the next one has a blast radius ''measured in the tens of kilometers''. And what allows Lelouch to pull his aforementioned global OhCrap moment is getting control over an entire arsenal of these things. So yes, when it comes to Mass Oh Craps, Code Geass '''delivers'''.
* ''Manga/DragonBall'' does this a lot. When Goku or his opponent powers up, Krillin and anyone watching will get really scared. Just like with the BigEater thing, they never, ''ever'' get used to seeing this done, and stand gape-mouthed throughout the entire scene. Jeez, Krillin, at least make yourself useful and bring the guy some Gatorade!
* Dead serious one in ''[[Anime/NeonGenesisEvangelion End of Evangelion]]'' when [[spoiler: Instrumentality starts.]] Repeated in ''Anime/RebuildOfEvangelion'' under slightly different circumstances.
* ''Manga/{{Bleach}}'' likes this trope:
** Aizen's reality-bending, Xanatos-piling shenanigans cause this several times. Chapter 364 and 376 are this trope for all the Shinigami. And again in Chapter 392 where it turned out that the person Hitsugaya stabbed [[spoiler: was not Aizen, but [[TheWoobie Hinamori]].]]
** [[TheEmperor Yhwach's]] CombatPragmatist tactics in the Thousand Year Blood War Arc do this to Soul Society ''twice'' in quick succession. First, in Chapter 490, [[spoiler: Yhwach's herald announces the invasion of Soul Society in 5 days...then Yhwach begins the attack a few hours later.]] Second, in Chapter 546, [[spoiler: Yhwach gets around his inability to leave his own realm for more than a short time...by ''transporting Seireitei INTO his own realm''.]]
** In Chapter 577, nearly everyone in Soul Society, Shinigami and their enemies the Vandenreich alike, do this when [[spoiler:Gremmy Thoumeaux summons a giant meteor to crash down on them. Fortunately, Kenpachi destroys it in time.]]
* A RunningGag in ''Manga/OnePiece'' is the normal folks' responses to the Straw Hats' over-the-top antics.
-->(After Zoro has just [[ImplausibleFencingPowers cut a train car in two]])\\
'''Lulu:''' Y'know, if you guys are gonna keep doing stuff like that, you should tell us first!\\
'''Luffy:''' You heard me say "cut this," right?\\
'''Lulu:''' I didn't think he '''COULD!!'''
** That, along with the faces the Straw Hats (minus [[TheStoic Robin]]) themselves make when ever they're surprised by something, as seen in the page image above.
*** The fact that Robin never has such expressions is a running gag within a running gag, no matter ''how'' insane the situation is. Even if the utterly fearless Luffy and Zoro have OhCrap expressions, Robin will always be [[TheStoic completely unfazed]].
*** Of course, these are a few exceptions. Most notably, when the Straw Hat Crew see these towering silhouettes standing in the fog (Of course, [[spoiler:it's just a weather effect from being up in Skypeia, but the crew doesn't know that]]). There's a chilling silence where everyone looks like they're about ready to wet themselves, including Robin. Even a massive gorilla man they were fighting a minute ago looked like he was about ready to freak the hell out.
** At Marineford when [[spoiler:Luffy unconsciously uses his Haoushoku Haki, knocking many {{Mooks}} out in the process, this is the reaction of every marine who has even an inkling of what he just did.]]
** Even earlier, when Whitebeard realized who Luffy is and why he's here, he says the younger captain won't live through this battle. Luffy promptly tells "[[WorldsStrongestMan Whitebeard]]" [[PhysicalGod Edward]] [[TheDreaded Newgate]] to [[DidYouJustFlipOffCthulhu shut up]], because that's not for him to decide. The ''[[UpToEleven entire planet's military force]]'' proceeds to Oh Crap en masse.
** When [[spoiler: Blackbeard ''steals Whitebeard's Devil Fruit Powers'', the ''entire world'' goes OhCrap.]]
* The grand finale of ''Manga/DeathNote'', where [[spoiler: team leader Light is outed as the mass murderer Kira that the team have been hunting.]] Their reaction is mostly this strong because [[spoiler: Light's reaction to Near's accusations is to take an EvilLaugh and make it quite thoroughly his own.]]
* A ''huge'' one in the ''LightNovel/FullMetalPanic: The Second Raid'' finale. As Sousuke unleashes the full power of the [[FullContactMagic Lambda Driver]] and blows away Gates, his teammates are like '''holy crap'''.
** A smaller one is also in the first season finale. After defeating Gauron one last time, TheStoic Sousuke uses the opportunity of parting words to pull off a PrecisionFStrike. Cue to everyone gasping loudly. Justified in that he never, ever swears -- not even by accident -- so him calling someone an S.O.B. is quite a shock for others.
* In ''Franchise/{{Digimon}},'' split screens of the whole cast staring in horror is pretty much standard procedure whenever last week's FinishingMove proves to be this week's [[TheWorfBarrage Worf Barrage]]. Typically, one character after another is added to the split screen with a rapidfire choom-choom-choom sound effect until all are shown.
* The manga ''Manga/LittleHouseWithAnOrangeRoof'' has one of these after Shoutaro and Natchi realize they both got conned into buying the same house.
* In ''Anime/YuGiOhGX'' when [[spoiler: Judai's eyes turn gold after Mad King Brron 'killed' his friends in front of him and he begins to be as brutal as you can be in a card game]], everyone watching the duel but Judai.
* ''Anime/YuGiOh5Ds'': Everyone in Neo Domino City when [[spoiler: [[PersonOfMassDestruction Aporia]] is formed, summons his Machine Emperor and starts pelting them with lightning]]. [[spoiler: Then when they think it's all over, [[FromBadToWorse the sky cracks]], and the [[OminousFloatingCastle Ark Cradle]] appears, [[ColonyDrop on a collision course with the city]].]]
* ''Manga/FullmetalAlchemist'' had a couple of these, but the most memorable would be when [[spoiler:the [[BadassArmy Briggs troops]] subdue and capture 90% of Central Headquarters,]] and everyone starts celebrating. All of a sudden:
--> [[spoiler: Bradley/Wrath:]] *over the broadcasting system* [[OhCrap Hello everyone.]]
** A more humorous one in the [[Anime/FullMetalAlchemist 2003 anime version]] where Edward hides in a crowd while duking it out with Mustang, not that it stops Mustang from unleashing a huge fireball at Ed and everyone else in range.
* ''{{Anime/Pokemon}}'' gives us one through ''Facing Fear With Eyes Wide Open''. [[note]]The entire premise of the episode is that Ash is trying to get his Oshawott to stop freaking out and closing his eyes whenever he goes underwater - the point of all this is that it will give Aqua Jet a non-zero accuracy rating. As a result of Scraggy [[IdiotBall agitating a bunch of Foongus]], Ash and Oshawott are forced to go underwater and grab some seaweed to cure the resulting poison; needless to say, the local Tympole and their Palpitoad boss aren't willing to share. Oshawott is getting bombarded by Bubble attacks from every direction and attacking aimlessly in the process... up until he finally decides to give opening his eyes a shot. Once he realizes that there's no problem with his vision underwater, Oshawott effortlessly thwarts the latest barrage with one swing of Razor Shell. While a Tympole's eyebrows never really move, their facial expressions and the sound of their voices at this development literally scream "'''''WE'RE FUCKED!!!'''''"[[/note]]
* ''Manga/{{Toriko}}'' tops them all with a ''global'' OhCrap. [[PersonOfMassDestruction Zebra]] getting released from jail made... the entire human world crap itself. A fortune teller told his CrystalBall the word 'Zebra' and the ball wisely broke itself. The global economy nearly crashed. Predicted damages would be in the quadrillions of yen. A few small countries disappeared. '''This is just from the rumor that he would be released.''' To put it into perspective, Zebra was sent to jail for eating over two dozen ''species'' '''into extinction'''. An appetite like that would make any food-themed world panic.
** The news of the Four Beasts' awakening causes a panic that dwarfs the upheaval caused by Zebra's release. The entire population of the Human World retreats to the center of the Human World, leaving the borders completely deserted. Wholly justified, since the Four Beasts are horrifically powerful denizens of the [[DeathWorld Gourmet World]] that prey exclusively on humans.
* ''Manga/FairyTail'': PlayedForLaughs with Erza's first appearance.
** Then later, ''everyone'' after [[spoiler:[[DiabolusExMachina Acnologia's arrival]] on Tenrou Island]].
** And, once more, when Ezra steps forward in the Pandemonium game. [[spoiler: In a dungeon of 100 monsters, where each person is expected to challenge five or so, she challenges all 100, including an unbeatable monster.]]
*** Only Natsu and Grey are not doing this. They're LAUGHING!
** Oh Crap doesn't begin to describe the looks of shock on everyones' faces when the Eclipse Gate finally opens [[spoiler:and a Dragon emerges. Followed by more Dragons.]]
* ''Anime/MobileSuitGundamSEED'' is ''very'' fond of the spit-screen version of this trope. Especially noticeable when [[spoiler:ZAFT fires the GENESIS for the first time]]; pretty much the whole cast goes slack-jawed at the massacre.
* Happens in ''Manga/{{Naruto}}'', when [[spoiler:the real Uchiha Madara shows up and starts [[ColonyDrop dropping asteroids on people]].]]
** Happens again later, when he frees himself from the Edo Tensei contract thus making himself, for all practical purposes, immortal and invincible, and shattering the last hope they had of getting rid of him.
* In the ''Manga/AxisPowersHetalia'' movie, the characters do this when they find out that England had put [[LethalChef his home-made scones]] into the gift bags they gave the invading aliens.
* ''Anime/{{Hellsing}}'' gives this treatment to various characters but the most telling instances are when Warren SS vampires tremble in fear of [[spoiler: Seras]] and when two entire ''armies'' attack Alucard "lest something dreadful happen."
* [[TheDreaded Dessler]] of ''Anime/SpaceBattleshipYamato'' causes this three times, starting with the second season: the first time he merely needs to reveal he's still alive to cause the bridge crew of the ''Yamato'' to go from cheerfulness at their latest victory over the White Comet Empire to terrified horror; the second time the ''Yamato'' is about to start the final battle against the White Comet when Dessler shows up and starts teleporting starfighters before the ship, with the crew remembering with horror about the last time this happened; in the third season, by which time he had decided to ally with Earth, Dessler is informed that the warship causing trouble to some of his newest subordinates is the ''Yamato'', and his barely restrained rage at discovering how they had attacked a ship they had been specifically ordered to ''not'' attack causes this.
* In ''LightNovel/{{Baccano}} 1935-B - Dr. Feelgreed'', the Daily Days collectively loses its shit upon the discovery that [[spoiler:[[TheDreaded Claire]] [[PsychoForHire Stanfield]] has started working for [[MadScientist Huey]] [[ManipulativeBastard Laforet]]]].
* ''HajimeNoIppo'': Date starts talking behind Takamura's back, while Sendo, Mashiba and his sister, Okita and Saeki agree. [[spoiler: Only to find out that Takamura was in the same bar the whole time.]] [[Funny/HajimeNoIppo It goes as well as you'd expect.]]
* ''Manga/RosarioToVampire [=Capu2=]'': In Episode 8, this is Kurumu, Mizore, and Yukari's understandable reaction when Tsukune unleashes Inner Moka to put a stop to their fight; Inner Moka proceeds to T.K.O. all three of them with a single kick.
[[/folder]]

[[folder:Comic Books]]
* In ''[[ComicBook/{{Cerebus}} Cerebus: Church & State]],'' Cerebus has become (a very cranky) pope. His every word is therefore divinely true. At one point, a bunch of his followers are cheering him as he walks into his HQ. Cerebus interrupts them with, "ANYONE WHO ''MOVES'' BEFORE MOST HOLY COMES BACK OUT WILL SPEND ''ETERNITY'' SIPPING LAVA THROUGH AN IRON STRAW!" The next panel is a hundred frozen followers, and a hundred separate "Oh crap" thought bubbles.
* Issue 224 of ''ComicBook/ArchieComicsSonicTheHedgehog'': the last few panels are everyone in New Mobotropolis staring in fear up at [[spoiler: the rebuilt Death Egg]].
* In ''ComicBook/DeathOfTheFamily'', this reaction is shared by pretty much every one in Gotham when SelfDemonstrating/TheJoker comes back, including the villains: Penguin, Poison Ivy and even Harley aren't exactly overjoyed to see him back.
* Early in Ed Brubaker's ''ComicBook/{{Daredevil}}'' run, everyone in Ryker's, even a guard and an inmate having a savage brawl, dropped what they were doing when they heard the news: [[WhamLine "Bullseye has come to Ryker's."]]
* Often in ''ComicBook/{{Asterix}}'', the pirates are getting set to take a vessel--uh-oh, guess who are on board!
[[/folder]]

[[folder:Fanfic]]
* [[FanFic/WeaverNine The Society]] tries using replicas of ''[[TheDreaded The]]'' ''[[OurAngelsAreDifferent Simurgh]]'' to psyche out Leviathan, as well as gauge his reactions and senses. While the success of that experiment is debatable, it caused a panicked retreat among the Protectorate force.
* ''FanFic/DungeonKeeperAmi'': The general reaction of the forces of good to Ami's victory over the avatar. Later, their reaction to her consuming a Lesser Aspect of Crowned Death.
* In ''FanFic/AnEntryWithABang!'', the marauding pirates get this reaction when they find out that Earth has nukes and isn't afraid of using them.
* The ''FanFic/PonyPOVSeries'' has a very good one in the [[BadFuture Dark World]] arc, when [[spoiler: [[SixthRangerTraitor Rancor]] literally stabs Discord InTheBack]]. The action grinds to a stop as every character freezes in shock at the unexpected twist, and everyone realizes that this changes ''everything'' -- even [[TheVoice the Nameless Passenger]] realizes that its well-scripted plans have been [[SpannerInTheWorks ruined]] now.
** Later in the same arc, there's another when [[spoiler: everyone discovers that Pinkie's been SecretlyDying since her Element of Rage was shattered. Even [[OneWingedAngel Odyne!]][[FinalBoss Cruelty]] freezes up in shock.]]
* ''FanFic/TheGreatAlicornHunt'': The Mane Six have all ascended into Alicorns, and two Galas (one for the adults of the upper crust, one for their kids) are being held after their official coronation. During the Junior Gala, the four members of the CMC (and their newest friend, Fluttershy's little brother Breezy Shy) inform a group of colts and fillies from Manehatten, who are also attending and have a history with Babs Seed, that they're kin to the new princesses. Pennyworth and his goons don't believe them, leading to a [[CurbStompBattle big fight]] with the CMC and Breezy. Later, as the bullies are in the infirmary, they're plotting their revenge... and have this reaction when they realize the CMC were telling the truth, [[spoiler: courtesy of an angry Princess Applejack showing up, having overheard everything they'd been saying.]]
* ''FanFic/SonicXDarkChaos'': Everyone - including [[{{Satan}} Maledict]] himself - has one of these in Episode 75 when [[spoiler: Dark Tails steals the Chaos Emeralds and becomes a god]].
* ''Escape From The Hokage's Hat:'' A large squad of over 50 Iwa ninja bump into Tsunade's group (Tsunade, Naruto, Hinata, Shizune and Hana) and engage them in a fight (read: surprise attack). While frustrated at how the group is somewhat surviving the attack, many find themselves constantly switching from sheer abject rage to deep terror when they start noticing that there is a blond 13 year old boy in the group. Who is skilled at Taijutsu. Moves incredibly quick. And knows how to use the Rasengan. Just like Konoha's Yellow Flash.
[[/folder]]

[[folder:Films -- Animated]]
* A fairly funny yet serious one from ''WesternAnimation/ABugsLife'' happens after Flick sees a feather on the ground. Flick stares for a second, has his personal OhCrap moment, and runs off screaming. The other bugs watch him go, and the bird lands right behind them, chirps, and the circus bugs all run after Flick, screaming as well.
* In ''WesternAnimation/SinbadLegendOfTheSevenSeas'', Eris makes a rather [[BigEntrance dramatic entrance]], which left nearly everyone (particularly the Council) freaking out, and stunned for several minutes after her departure.
* PlayedForDrama in ''{{Disney/Mulan}}'', where [[spoiler: the soldiers' happy-go-lucky song "A Girl Worth Fighting For" is [[MoodWhiplash brutally ended mid-verse by the sight of a destroyed village]]]]. Cue horrified reactions and non-comical {{Jaw Drop}}s from everyone present.
[[/folder]]

[[folder:Films -- Live-Action]]
* In ''Film/{{Airplane}}'', this happens because the stewardess is asking if anyone knows how to fly a plane. In the sequel, it's because [[MustHaveCaffeine they're out of coffee]].
** From the same creators, ''[[Film/TheNakedGun The Naked Gun: 33 1/3]]'' showcased this during a confrontation on-stage at the Oscars between Drebin and Rosco. Rosco's got a gun, Drebin has the bomb Rosco wants to trigger. Drebin's solution? Trade the [[WhatAnIdiot gun for the bomb]]. Cue {{FacePalm}}s from ''everyone'' with their hands free.
* In ''Film/{{Repossessed}}'', the voice of the exorcised Satan bellows "I'll be back!", to which everyone proclaims "Oooh, shit!"
* A planetwide version happens offscreen, but sensed by Obi Wan Kenobi in ''StarWars: ANewHope'':
-->"I felt a great disturbance in the Force, as if millions of voices suddenly cried out in terror [[EarthShatteringKaboom and were suddenly silenced]]. I fear something terrible has happened."
** The movie's manga adaptation makes a point of portraying that one exact MassOhCrap.
* At the end of ''Film/Jaws3D'', when everyone sees the shark heading their way.
* In the movie ''Film/Speed2CruiseControl'', there's several different shots of people looking out and saying "Oh, shit!", because they realize the ship is going to crash into a port.
* ''[[Film/PiratesOfTheCaribbean Pirates of the Caribbean: At World's End]]''. At first when the pirates saw the first ship of the company they started cheering to attack, but they soon stop when the fog reveals the rest of the armada.
* In ''Film/ClashOfTheTitans'' (the new version, not the classic), when Hades makes his appearance in the throne room scene, you can tell every person in the room just thought "OhCrap", or some variant of it, most especially the queen who had just finished saying [[AGodAmI that they were the new gods.]]
* This happened with Biff and his thugs in ''Film/BackToTheFuture'', when they were chasing Marty and realized they were about to run into a manure truck!
* ''Film/RiseOfThePlanetOfTheApes'': [[spoiler:Caesar speaks.]] The camera jumps around the room, showing that ''everyone'' -- even the ''apes'' -- can't believe it. And if you saw it in theaters, ''the audience'' probably had the exact same reaction. What makes it so effective is that the audience is still laughing at the "[[MythologyGag get your stinking hands off me you damn dirty ape]]!" line that they are caught completely off-guard by the [[spoiler:WhamLine]].
* In ''Film/TheHitchhikersGuideToTheGalaxy'' movie, after the [[ObstructiveBureaucrat Vogons]] announce to the entire Earth that it is to be [[EarthShatteringKaboom demolished to make way for a hyperspace bypass]], we get shots of various locations indicating that ''every single person on earth is '''screaming in terror''''', from places like New York and Rio De Janiero, then a flock of sheep merely bleating in their pasture as Vogon construction ships come into the atmosphere. This lies somewhere between [[CrowningMomentOfFunny hilarious]] and utterly terrifying.
** What makes it funny is the one [[StiffUpperLip serene-looking old lady]][[note]]played by [[GeniusBonus Douglas Adams' mother]][[/note]], [[SpotOfTea sipping her tea]]. She was not told what the scene would be, so she's hardly reacting to the screaming chaos around her. They decided to ThrowItIn.
* ''Film/RevengeOfTheNerds'' has one where the Alpha Betas' Partygoers realize a fire-breathing reveler has just set their dorm on fire
--> '''Everyone''': "Oooooh, ''shit!''"
* A mass chorus of "Oh, shit!" in ''National Lampoon's Class Reunion'' immediately follows the shrink's revelation that, yes, the class prank pulled on Walter really ''had'' been nasty enough to turn him into a vengeful serial killer.
* ''Film/{{Apollo 13}}'': "Houston, we are venting something out into space." All the frantic discussions in the spacecraft and Mission Control stop dead upon hearing Jim Lovell make that announcement.
* ''Film/PacificRim'': When Mako activates Gipsy Danger's plasma caster inside the hangar.
** Also, when Mutavore breaches the anti-kaiju wall without any sort of problem at all, pretty much everyone had this sorta reaction.
** Slattern's appearance.
--> [[spoiler: It's a Category 5 ... the first of its kind.]]
* ''[[https://www.youtube.com/watch?v=z6BxSbx1Fm0 The Day Britain Stopped]]'', a BBC 2003 Mockumentary about the over-burdened transport systems, many eyewitnesses have this response when [[spoiler: two airplanes crashes in mid-air over a residential area.]]
[[/folder]]

[[folder:Literature]]
* In ''Literature/TheWheelOfTime'', the tenth book, ''Crossroads of Twilight'' could be essentially summed up as 800+ pages of every channeler on the planet going through an ''epic freak out.'' Granted, it's because they're sensing enough of the One Power to "crack the world like an egg," and they don't know whether it's being used by the good guys or the bad guys. Though, eventually, several characters get tired of freaking out, and basically state that if the beacon of power was going to destroy the world, it would have done so already.
* In the ''Literature/LeftBehind'' book ''Glorious Appearing'', during the 'sheep and goats' judgement, this is the reactions of the unsaved and those who had taken the Mark of the Beast when Jesus condemns them to the Lake of Fire for not caring for "the least of My brethren", referring to Israel. Basically saying that if you're not a friend to Israel and the Jews during the Tribulation, you're going to Hell.
-->'''Jesus Christ:''' Depart from Me, you cursed, into the everlasting fire prepared for the devil and his angels. For I was hungry, and you gave Me no food; I was thirsty, and you gave Me no drink; I was a stranger, and you did not take Me in; naked, and you did not clothe Me; sick and in prison, and you did not visit Me. Assuredly, I say to you, inasmuch as you did not do it to one of the least of these, you did not do it to Me. You will go away into everlasting punishment.
* ''Literature/PrinceCaspian'', Aslan's roar:
-->"Aslan, who seemed larger than before, lifted his head, shook his mane, and roared. The sound, deep and throbbing at first like an organ beginning on a low note, rose and became louder, and then far louder again, till the earth and air were shaking with it. It rose up from that hill and floated across all Narnia. Down in Miraz’s camp men woke, stared palely in one another’s faces, and grasped their weapons. Down below that in the Great River, now at its coldest hour, the heads and shoulders of the nymphs, and the great weedy-bearded head of the river-god, rose from the water. Beyond it, in every field and wood, the alert ears of rabbits rose from their holes, the sleepy heads of birds came out from under wings, owls hooted, vixens barked, hedgehogs grunted, the trees stirred. In towns and villages mothers pressed babies close to their breasts, staring with wild eyes, dogs whimpered, and men leaped up groping for lights. Far away on the northern frontier the mountain giants peered from the dark gateways of their castles."
** Another in ''Literature/TheLastBattle'', when every thinking being in the world sees Aslan standing in a doorway. [[spoiler: This is one of the most heavy-handed of the Christian images in the whole series, as Aslan is literally separating good from evil, with good going past him through the door to Heaven, and evil...not going through the door. Most approaching the door are completely terrified of him. When some looked, their expressions changed to fear and hatred (p.144, Macmillan edition, 1988) and they passed away into the shadow. Some of the others (the ones who did not pass into the shadow) were very frightened, but not all.]]
** In ''Literature/TheVoyageOfTheDawnTreader'', the sailors react this way when they realize the implications of landing on the island where dreams come true. (It sounds like an absolutely fantastic place... until you remember that Nightmares are also [[RealDreamsAreWeirder dreams]].)
-->There was about [[OhCrap half a minute’s silence]] and then, with a great clatter of armor, the whole crew were tumbling down the main hatch as quick as they could and flinging themselves on the oars to row as they had never rowed before...
[[/folder]]

[[folder:Live-Action TV]]
* In ''Series/DoctorWho'', the entire world goes into panic when [[spoiler: [[http://www.youtube.com/watch?v=mgZzCrpqT5E "EXTERMINATE"]]]] is broadcast over and over on the public airwaves.
** The Doctor engenders this in the ''Daleks'' in [[spoiler: [[http://www.youtube.com/watch?v=oYoLG_iP9Ec Bad Wolf]]]] when he refuses to surrender to the Daleks in spite of them holding Rose Tyler hostage, and makes a BadassBoast about how he's going to rescue her from the middle of the Dalek fleet, he was going to save the Earth, and just to finish off, he was going to wipe every last stinking Dalek out of the sky and when they point out that he has [[IndyPloy no weapons, no defenses, and no plan]], his response is to say, "Yeah. And doesn't that scare you to death?"
** Also in "The Time of Angels", when the Doctor and his team realise [[spoiler:that every one of the statues in a 6-story maze full of them is an Angel. And they're waking up.]]
** And in "The Fires of Pompeii", when Vesuvius explodes.
** '''[[Recap/DoctorWho2013CSTheTimeOfTheDoctor EMERGENCY EMERGENCY THE DOCTOR IS]] [[spoiler: REGENERATING]]!'''
* After all the characters of ''Series/BuffyTheVampireSlayer'' suffer magic-induced memory loss, they collectively freak out (all in the same shot at once) at seeing two lowly vampires at the door, because they have forgotten they're superheroes, providing us with this [[http://www.jetwolf.com/hof/hitlist/buffy/005.jpg hilarious image]].
** One episode of ''Series/{{Angel}}'' had the scene where Marcus Hamilton punches a hole through a guy's torso and Harmony, Lorne, and Eve all [[TheScream freak out Macaulay Culkin-style]].
* Boomer of ''Series/BattlestarGalacticaReimagined'' in Exodus, Part 2 is able to do this to a room full of Cylons on Colonial One with two simple words: "Adama's back."
* In the SeriesFinale of ''Series/{{Seinfeld}}'' the private plane the MainCharacters are on looks like it's gonna crash and they're all freaking out . . . except [[CloudCuckooLander Kramer]], who shouts, "''Oh, I'm ready! GLORY HALLELUJAH!!''"
* In the ''Series/StarTrekDeepSpaceNine'' episode "The Die Is Cast", all inhabitants of the Warbird bridge (including Garak) get this when they realise that [[spoiler: they were set up - the Founders are no longer at their planet, but the Jem'Haddar are at full force.]]
-->[[spoiler: Garak: It was all a trap. They were waiting for us all along...]]
* Happens in the ''Series/PowerRangersSamurai'' episode "The Master Returns". When Xandred actually gets pissed enough to leave the Netherworld to kick someone's ass, despite the fact that he'd die from dehydration within minutes in the human world, this is the reaction from everyone nearby. And oh boy, is it justified.
* ''Series/GameOfThrones'':
** In the first season episode "The Pointy End" when Barristan Selmy, known colloquially as "Ser Barristan the Bold" is forcibly retired from the Kingsguard by Cersei despite them holding their position for life, he strips off his armor and declares he will "die a knight" to which Littlefinger jokes, "A naked knight" eliciting a laugh from the assembled court. Barristan then draws his sword in anger and everyone stops laughing at once. More to the point, they stop laughing and all look positively terrified. It's only when Barristan throws his sword at Joffrey's feet and storms out that everyone finally starts breathing again.
** In the episode "Baelor", the majority of the nobles and counselors attending the [[spoiler:judgement of Ned Stark]] suffer one when [[spoiler:Joffrey decides to execute him, something that wasn't in the plan]]. Also, you can notice one person who isn't surprised, and who is actually ''smiling'': [[spoiler:Littlefinger]].
** Occurs again in the season 3 episode "Mhysa" in a more subdued way after [[PuppetKing King Joffrey]] mouths off to his grandfather [[EvilChancellor Tywin]] and tries to assert his authority. The entire Small Council, the Queen, and even Joffrey himself have a different variation of an "oh shit" expression.
* The main characters of ''Series/{{Sherlock}}'' do this at the end of "His Last Vow" from four simple words:
-->[[spoiler:'''Moriarty:''' [[BackFromTheDead Did you miss me?]] ]]
[[/folder]]

[[folder:ProWrestling]]
* During the 2009 Royal Rumble, [[http://www.youtube.com/watch?v=AU7VDwTCS_w those in the ring]] had this reaction when they heard a [[TheUndertaker *Gong*]]. As the men inside of the ring lined up, Jerry Lawler knew [[ThisIsGonnaSuck what was bound to happen]].
* [[http://www.youtube.com/watch?v=E82B_GQkxUU Kevin Nash]] also created this, both Sheamus and Kofi Kingston knew it wasn't going to end well.
* Ground Zero: In Your House… when the match between ShawnMichaels and TheUndertaker got out of hard, the entire locker room ran to stop the fight… this was the reaction to everyone who saw it, especially when Taker jumped into the crowd.
* After being slammed [[BreakTheCutie emotionally by Daniel Bryan]], AJ Lee vented out her rage on the next [[Wrestling/NatalyaNeidhart unfortunate available person]], which generated this.

* The famous "silent scene" in ''The Government Inspector'' (or ''The Inspector General'') by Creator/NikolaiGogol is an ''epic'', several minute long MassOhCrap moment, described in great detail.

[[folder:Video Games]]
* This trope was the result of the original LeeroyJenkins' charge into the Upper Blackrock Spire Rookery in ''VideoGame/WorldOfWarcraft''. It's also the reaction of the entire raid when a main tank dies unexpectedly or the boss hits his enrage timer. A smaller version happens during dungeon groups composed mostly of DPS (e.g. three rogues and a priest or shaman) with no main tank when the healer/heal tank dies.
* ''VideoGame/WildArms1'' had the Quarter Knights pull this off when [[OmnicidalManiac Mother]] tells them about her true objectives. It was even worse in the remake.
* ''VideoGame/FinalFantasyVI'' has this when a message is brought to the Elder of Narshe about [[spoiler:the Empire attack]]. Everyone present (the Elder, his men and all the player characters so far) take on their shocked face.
* ''VideoGame/FinalFantasyXIII'' has an excellent instance of this, with looks of abject horror from the entire party when [[spoiler:[[PresidentEvil Primarch Galenth Dysley]] reveals his true form as the [[PhysicalGod fal'Cie]] [[BigBad Barthandelus]]]].
* In the final mission of ''VideoGame/MassEffect3'', [[spoiler:Hammer Task Force is preparing to storm the Conduit, when [[BigBad Harbinger]] lands on the far side.]] The entire force panics, and makes a desperate charge. [[spoiler:It almost works.]]
** Earlier on Mars, all of the Cerberus troops had this reaction upon realising ''who'' the Alliance had sent.
--> '''Cerberus Trooper''': Holy shit! It's ''[[TheDreaded SHEPARD!]]''
** The Reapers actually appear to do a double-take upon noticing the utterly ''enormous'' fleet pouring through the Mass Relay, hellbent on retaking Earth and [[spoiler: the Citadel]] from their control. How big is the fleet? Potentially, it's AllOfThem. All the turians, all the krogans, all the quarians, all the geth, etc.
** From the tie-in Twitter feeds, the Reapers are implied to be having a collective MassOhCrap upon realising that none of their forces during the invasion of Earth have managed to confirm the whereabouts of "[[TheDreaded Hostile Target Shepard]]". Because that means Shepard is ''still out there!''
** From ''VideoGame/MassEffect2'', the entire team at Project Arrival when Shepard breaks through the sedatives and wakes up, and s/he is PISSED! Cue CurbStompBattle.
* In ''Videogame/IMissTheSunrise'', this is the crew's reaction to encountering a jamming pulse for the first time. Which is a pretty justified response, considering that it [[FinalDeath disables the safeguards]] that make NonlethalWarfare nonlethal.
* Anytime Lu Bu appears in the ''VideoGame/DynastyWarriors'' games, expect every {{Mook}} and even some generals to react this way.
* In VideoGame/DragonAgeOriginsAwakening, you can induce this in a bunch of kidnappers if you imported a character from the original game by pointing out that you are the Hero of Ferelden. Some of them apparently jump off a cliff rather then face you.

[[folder:Web Animation]]
* ''WebAnimation/SuperMarioBrosZ'': Episode 6, when [[HeroKiller Mecha Sonic]] shows up. And again, when he does [[http://www.youtube.com/watch?v=BNPAQ3H1szY this]]. Luigi's OhCrap expression is particularly [[CrowningMomentOfFunny epic.]]
[[/folder]]

[[folder:Web Comics]]
* A ''musical'' version of this can be seen in [[http://www.youtube.com/watch?v=6YUAnhM4TY4 this]] ''Webcomic/CyanideAndHappiness'' short.
* This was the general reaction to Gilgamesh Wulfenbach of ''Webcomic/GirlGenius'' [[http://www.girlgeniusonline.com/comic.php?date=20071128 one-shotting a heavy war machine with a bolt of lightning.]] It wasn't a harbinger of doom for most of the characters who had their reactions depicted, but it certainly caused a city-wide double take and hanging jaw.
* ''Webcomic/TheOrderOfTheStick'': In one of the [[http://www.giantitp.com/comics/oots0825.html strips]] (warning: spoilers!) we have the resistance scouting party's reaction when they return to base and find [[spoiler: that not only have the villains overrun it, but ''[[TheDragon Redcloak]] himself'' is there.]]
** Another example: The [[spoiler:remaining members of the Order, having just [[WhamEpisode been through a lot]] are at a door a the end of a hallway when ''[[BigBad Xykon]]'' opens it from the other side.]]
* Inverted in Webcomic/DMOfTheRings. When a massive troll attacks the group, they gleefully rush to finally kill something besides orcs.
* In ''Webcomic/EightBitTheater'', the ''entire universe'' goes OhCrap when [[spoiler:Black Mage becomes the ruler of Hell.]]
[[/folder]]

[[folder:WebOriginal]]
* ''WhateleyUniverse'' story ''Ayla and the Great Shoulder Angel Conspiracy'', when Elite League finds out just how horrific their simulation battle is going to be, and just how badly boned they all are.
-->'''Gunnery Sergeant Bardue''': Okay Elite League, welcome to a little simulation that I like to call DARK [[PersonOfMassDestruction TENNYO]]!\\
'''entire team''': Oh fuck.
* In {{Literature/Worm}}, this is the reaction to the realization that the Slaughterhouse Nine have arrived in the city by any teams that have found out before they announce their presence. Aftewards, it is the reaction of the rest of the city.
* In ''RoosterTeeth'''s "LetsPlay {{Minecraft}}" episode one, we get this. Gavin, who had been playing the PC version of Minecraft before they went to the 360 version, disappeared to make a bucket and get some lava. He returns to find the house the others built... [[{{Troll}} and dumps the lava on top of it.]] At that point, we have this reaction:
-->'''Ray:''' Hey, guys? [[DullSurprise There may, or may not, be lava engulfing the house right now]].
-->'''Others:''' ''[FREAK OUT]''.
* In ''CounterMonkey'' Spoony describes this reaction from the party when they realize that the person they just threw a bottle of acid into the face of is not, as they thought, an evil cultist, but their current employer: Tempus Thales, the brutal, unkillable avatar of a war god. At their next session they're feeling optimistic that he'll get over it if they just stay out of his way, only to encounter this again when he reveals his hideously burned face to the city and declares a ten thousand gold bounty on the party member who threw the acid.

[[folder:Western Animation]]
* During the ''WesternAnimation/TotalDrama'' "Celebrity Manhunt" special, Courtney loses control of DJ's bus which is headed towards a cliff. The camera then cuts to everyone in the bus either making OhCrap faces or screaming in terror. Except [[DissonantSerenity Izzy]] and [[TheStoic DJ's mama]] that is.
* ''WesternAnimation/TheBoondocks'': The reaction to [[spoiler: Bushido Brown's death]].
* In the penultimate ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'' episode "Alive!", the look of triumph on Luthor's face becomes one of sheer horror shared by the rest of the Legion of Doom when they realize that they resurrected [[spoiler:''{{Darkseid}}''.]] http://www.youtube.com/watch?v=v0kO0Jfy5NQ
** A smaller one in "Flashpoint" when [[spoiler:SelfDemonstating/LexLuthor hijacks the League's space cannon]], courtesy of Franchise/{{Superman}}, ComicBook/{{Supergirl}}, ComicBook/GreenArrow, ComicBook/TheFlash and even the ComicBook/MartianManhunter, plus a bunch of RedShirts.
* Parodied in ''WesternAnimation/TheSimpsons'' with Troy [=McClure=]'s DNA video:
-->Troy: Hi, I'm Troy [=McClure=]!\\
* Alarm proceeds to go off as every single worker in the room retreats into a sealed room*
* Hip, Hop and King Koopa have one in ''WesternAnimation/SuperMarioWorld'' just before a giant Piranha Plant [[SwallowedWhole swallows them whole]].
* On ''WesternAnimation/MoralOrel'' the main RunningGag is that some adult in Moralton will give Orel a piece of advice which he'll misinterpret, leading to him doing extremely bad things while trying to do good. When Reverend Putty finally realizes this root cause of so much havoc, he addresses the whole town, telling them, "The next person that inadvertently sends Orel Puppington down the wrong path could be responsible for damning all our souls". Everyone in town gulps simultaneously.
* ''WesternAnimation/MetalocalypseTheDoomstarRequiem'' has one in song:
-->'''Pickles:''' Oh my god! Our old manager!\\
'''Skwisgaar:''' Oh mys gods! My old guitar teacher!\\
'''Nathan:''' Oh my god! Our old groupies!\\
'''Murderface:''' Oh my god! A douchebag nightmare!
* ''Franchise/LegendsOfChima'': the tribes' response to finding that Mt. Cavora has suddenly stopped flowing after they push back the Bat tribe swarm that was circling around it.

[[folder:Real Life]]
* A RealLife version literally resulted in NORAD having its EmergencyBroadcast System privileges revoked. The EBS, originally designed to warn of [[NukeEm nuclear attack]], would have NORAD or the White House send out a weekly test. On 20 February 1971, a NORAD staffer accidentally [[http://stlradio.net/pages/ebsaccident.htm loaded the tape instead for an Emergency Action Notification]]. An [[http://www.ae5d.com/ebs.html Emergency Action Notification]] was the EBS's own MassOhCrap It's TheEndOfTheWorldAsWeKnowIt warning (thus being an example of this trope in and of itself). The only expected reason that an EAN would be issued would involve either nuclear weapons, alien attack, or something else that would count as ApocalypseHow.
** And this isn't the only time this has happened -- the Emergency Action Notification MassOhCrap alert exists in the EBS's successor the Emergency Alert System, and there was an instance on June 26 2007 when [[http://www.rcfp.org/newsitems/index.php?i=4786 an EAN intended for test circuits ended up being broadcast on live air in the Chicago metro area]]. (The hiccup was related to FEMA testing of a new method of sending Emergency Alert System messages over satellite networks. In this case, [[http://www.fema.gov/media/fact_sheets/eas.shtm someone at the Illinois emergency management agency forgot to reset a switch to the "test circuits only" setting]].)
** There's also been a number of [[http://catless.ncl.ac.uk/Risks/23.96.html#subj2 state-level]] accidental MassOhCrap warnings sent by the Emergency Alert System, such as a typo by a National Weather Service employee of an EAS code resulting ''not'' in a weekly test but a MassOhCrap warning that the entire state of Florida needed to be evacuated due to nuclear fallout, an [[MassOhCrap EAN]] sent by mistake by a Las Vegas-area TV station (that was an upstream "relay" station for most of Nevada), and a mistaken MassOhCrap warning calling for the entire state of Connecticut to be evacuated.
** A ''real'' Emergency Alert System message tends to have this effect as well.
* [[http://www.cbsnews.com/stories/2010/04/01/world/main6354292.shtml In one hilarious case]], a bunch of Somali pirates were sailing in the night then they spotted a big ship, they thought a big ship would mean big ransom, so they opened fire hoping to intimidate them to surrender. But they soon realized what they fired on was the ''[[MuggingTheMonster USS Nicholas]]'', a U.S. Navy guided-missile frigate. You can guess how they reacted when they soon realized, via a burst from the ''Nicholas''' .50-caliber deck gun, what they were really up against.
** Repeated on a [[http://www.france24.com/en/20091007-french-navy-captures-pirates-attacking-supply-ship-# French Navy Command/Refuel ship.]]
* Pop Quizzes - ''damn'' them.
** Getting a test to realize that none of the questions were covered in class.
** Also giant chapter tests that the teacher took the pain to inform the class about ''the night before''.
* In 2006, Australia had finally qualified for the soccer World Cup after years of just failing to make it. Then, when the draw was made, most of the nation did this when we were drawn in the same group as Brazil. (On the other hand, the coach and team themselves said they were looking forward to the challenge. In the end, the score in Brazil vs Australia was only 2-0, which is a damn good result to have, even for a loss against the five-time world champion, and Australia made it into the second round.)
** Repeated for the 2014 World Cup. Australia were drawn in a group with Spain (current champions and probably the best team in the world at the moment), the Netherlands (2010 runners-up, still very strong) and Chile, who are also a very strong side. "Oh crap" indeed. This time Australia weren't so lucky; they lost to all three.
* The destruction of UsefulNotes/{{NASA}}'s Space Shuttle Orbiters in 1986 and 2003 certainly qualified as heart-stopping moments for Mission Control. [[http://www.c-spanvideo.org/program/175130-1 Viewers of NASA TV and C-SPAN were able to witness the blank stares of grim realization in Mission Control as communications are lost and reports of debris over Texas are relayed during Columbia's destruction.]] The flight director's heartbreaking words, "Lock the doors," are procedural to ensure that no one enters or leaves in such a crisis as data backup for an investigation immediately began.
** The first Orbiter built, the test vehicle ''Enterprise'' (yes, named after ''[[Franchise/StarTrek that one]]''), was not originally designed for space flight. Enterprise was designed internally by superstructure as "OV-101," Rather than an overly costly refit of her for operational use, NASA decided that a structurally-identical frame used for early tests would be fitted for flight instead: "STA-099." This became "OV-099," otherwise known as '''''Challenger'''''. Imagine the Mass Oh Crap and fandom-mourning moments that the Star Trek community would have doubly-suffered, on top of the general sadness of the tragedy, were it Enterprise that was destroyed that day.
*** Christa [=McAuliffe=] was NASA's second choice after figuring out it would be impossible to fit the costume of their original, Caroll Spinney in character as '''[[Series/SesameStreet Big Bird]]'''.
* Another serious example: When a major disaster gets broadcasted, and especially when we see the disaster unfold as is.
** Even regular TV shows, like ''Series/GameOfThrones'' and ''WesternAnimation/FamilyGuy'', would get this response if a critical scene [[WhamEpisode catches viewers by surprise]].
* From American politics, the Whigs in 1841 and Republicans in 1901 had one when their Presidents (UsefulNotes/WilliamHenryHarrison and UsefulNotes/WilliamMcKinley) died and their respective Vice Presidents (UsefulNotes/JohnTyler and TheodoreRoosevelt) succeeded them--men neither party wanted at all as President.
