->''"It's that moment of dawning comprehension I live for."''
-->-- '''Hobbes''', ''ComicStrip/CalvinAndHobbes''
The moment at which a character realizes that something really, ''REALLY'' bad is about to happen. Either that, or it already ''has'', and they are in big trouble because of it. They may not always say anything in particular when they do, but even if they don't, the look on their face clearly conveys to the audience their realization. This moment often features [[PrecisionFStrike stronger]] [[ClusterFBomb language]], and is when they truly realize that [[ExpospeakGag the solid organic waste is about to collide with the Rotational Air Circulation Device]].[[note]][[DontExplainTheJoke Shit hits the fan.]][[/note]] Sometimes the first few notes of [[http://www.youtube.com/watch?v=umgty3qGCcY Chopin's Funeral march]] is used as background music to highlight how grim the situation is.
They may feel that ThisIsGonnaSuck, and often exclaim, "YouHaveGotToBeKiddingMe" or perhaps "IWantMyMommy!" or sometimes even "ThisCannotBe" Other characters might emit a LoudGulp instead.
The effectiveness of this moment can be affected by the difference between their usual competence and confidence levels and how completely they are boned. Characters with low self-esteem or who are constantly crying out in terror are difficult (but not impossible) to make this trope work with. But that [[SmugSnake arrogant]], [[ArrogantKungFuGuy so far unbeatable]] supervillain suddenly realizing he's about to have his ass royally kicked? Now we're talking!
Can occur if one protagonist has been [[BatmanGambit luring the other one into a trap]], or if they just have some [[LookWhatICanDoNow shiny new skill]]. Or they may simply be a lower-level villain who's just had the very bad luck to be confronted with a hero impossibly out of his league. On occasion, [[ExplainExplainOhCrap they will be discussing the situation when they realize the full import of it.]] Related to ThisCannotBe, and the polar opposite of ObiWanMoment, when despite the bad situation someone still manages to look composed. May result in a HeroicBSOD for a heroic character, or even a VillainousBreakdown for a villainous character. Nine times out of ten, this will immediately follow [[WhatDoesThisButtonDo "What does this button do?"]]. The remaining tenth follow some other [[TemptingFate temptation of fate]]. Also a very common reaction when a villain, normally a ChessMaster, VillainWithGoodPublicity, or ManipulativeBastard, realizes he's just been the victim of an EngineeredPublicConfession. Some characters react with [[ThisIsGonnaSuck less despair and more apathy]]; others [[GonnaNeedMoreX look to their equipment]] for a solution. And for some, it is the [[HeroicBSOD crowning]] [[DarkestHour moment of]] [[DespairEventHorizon despair.]]
When this trope becomes [[LiteralMetaphor literal]], that's BringMyBrownPants--as Creator/BillCosby once said, "first you say it, then you do it!"
May also be a PrecisionFStrike for the person in question.
When most of the cast available in the scene does this expression, it's a MassOhCrap moment. If someone tries to explain the situation to someone else, and realizes ''half-way through their own explanation'' they're in real trouble, it's ExplainExplainOhCrap. If you realize you're in trouble ''after'' your explanation, it's a DelayedOhCrap. When you try to save some face by putting on a happy face, you make an OhCrapSmile.
