When Alice and Bob both CannotSpitItOut or have had an UnresolvedSexualTension for a long time, it's not rare that [[ContrivedCoincidence fate helps a little]] by making one of them trip for some reason (often [[BelligerentSexualTension a fight]]) and fall on the other. They may both lose their footing and fall to the ground, or the standing one might brace the impact against a wall. Either way, ''awk-ward.''

In some cases, they will [[InstantSeiza separate and apologize]], or Alice will [[NotWhatItLooksLike scream and slap Bob]], [[AccidentalPervert calling him a pervert]]. But if this trope is in action, neither will happen. By the magic (and surprise) of their sudden proximity, they will fall silent. They'll [[HeldGaze look intensely into each other's eyes]], forgetting their fight entirely. Everything around them will fade, and their lips will slowly get closer, before locking into a TrueLovesKiss. If there is no immediate kiss, it will at least be a NearKiss, and probably an AwLookTheyReallyDoLoveEachOther moment.

Compare CrashIntoHello, which has little chance to result in a kiss for obvious reasons.

A SisterTrope to the less romantic and more comic SuggestiveCollision, which can result in MarshmallowHell or ThanksForTheMammary but is [[MegatonPunch much less likely to end well]]. Compare MeetCute, which introduces a future relationship between two characters. Also see the logical conclusion, OfficialCouple.

Also a SubTrope of RuleOfRomantic and FallingInLoveMontage.

!!Examples

[[foldercontrol]]

[[folder:Anime & Manga]]
* This happens to Erza and Jellal in ''Manga/FairyTail''. Although it's unclear [[KissingDiscretionShot whether they actually kissed or not]], it's the first time they express their mutual love so clearly.
* Tenzo Crossunite and Mary Stuart of ''KyoukaiSenjouNoHorizon'' combine this with LoveAtFirstSight. Notably, Mary fits Tenzo's criteria of the kind of woman he likes: [[EveryoneLovesBlondes blonde]] and [[BuxomIsBetter buxomed]].
* ''Manga/MyMonsterSecret'': Akane tries to make a use of this trope when Youko and Asahi are locked in the former's room by [[spoiler:sending a sleepy Youko onto Asahi with a spring, or literally tilting the entire house so that they fall on each other.]] All her efforts are in vain.

* ''Disney/TheLionKing'' does this during the "Can You Feel The Love Tonight" montage with Simba and Nala tumbling down a hill.

[[folder:Literature]]
* In ''The39Clues'', [[HandsomeDevil Ian Kabra]] rescues [[ShrinkingViolet Amy Cahill]] and, in the process, somehow falls on top of her. This is quickly followed by a kiss, although the RelationshipUpgrade doesn't last long.
* ''I.Q.'': Thanks to a "helpful" [[AlbertEinstein Uncle Albert]], Catherine winds up playing out this trope with Ed after repeatedly falling into his lap on a sailboat.

[[folder:Live-Action TV]]
* In ''{{Smallville}}'', Clark and Alicia have one of these, only to be interrupted by [[spoiler:Alicia's psycho ex-doctor]].
* During ''Series/BuffyTheVampireSlayer'''s amnesia episode, "Tabula Rasa", Willow and Tara fall on each other and share a moment.

[[folder: Visual Novels]]
* In ''VisualNovel/KatawaShoujo'', Emi's route has this ''three times.'' First, Emi crashes into Hisao while running in the hallways - their first meeting. Second, Hisao and Emi have a pillow fight which ends with him on top of her [[NotWhatItLooksLike in bed,]] and his inner monologue comes to realize he has feelings for her. Finally, after they've started dating, the same thing happens again, but with Emi straddling Hisao, which [[IDidntMeanToTurnYouOn escalates]] into a relationship-solidifying h-scene.[[/folder]]
