->''Now Ernie rushed out into the street, his gold top in his hand,\\
He said, "If you wanna marry Susie, you'll fight for her like a man!"\\
"Oh, why don't we play cards for her?" he sneeringly replied,\\
"And just to make it interesting we'll have a shilling on the side."''
-->-- '''Creator/BennyHill''', [[http://www.youtube.com/embed/19wAAyxZhUo "Ernie, the Fastest Milkman in the West"]]

Two guys have one goal in common: getting the girl. In essence, a Cock Fight is what happens when the vying between the two suitors escalates into open hostility. Often occurs if neither was aware of the existence of the other, or when one has been courting the girl for a while. Typically, [[HomosocialHeterosexuality the fighters tend to focus on each other with the woman becoming secondary goal]] or, in a nastier tone, treated as a trophy.

This is a staple of romantic films but it can show up in any type of work. Usually, this happens ''before'' the girl's heart is clearly settled between her two suitors but, even when her choice is made and spoken out, there is still a chance for the Cock Fight to turn up since {{Romantic False Lead}}s are not known for giving up easily. If the losing side ''refuses'' to acknowledge defeat, the next step can be IfICantHaveYou.

When it comes to the competition itself, it is generally about displaying protectiveness, doing nice things for the girl, strength contests and other kinds of [[DoubleEntendre symbolic measurements comparisons]], preferably in front of her. More often than not, things can get out of hand -- sometimes up to ''physical'' confrontation -- if one of the suitors gets too close to the girl in front of his rival, or worse still, if he openly ''claims'' the girl for himself.

During such conflicts, the girl can either stay [[NeutralFemale neutral]] or try to intervene whether or not her choice is made. If she takes the second option, what she does can go from trying to soothe the guys' differences, telling them to shut up and stop fighting over her, or even [[ScrewThisImOuttaHere get the HELL out]] until they stop being stupid.

This is a subtrope of the LoveTriangle and related to TriangRelations. Highly probable in a TwoGuysAndAGirl setting. Often happens after a GreenEyedEpiphany.

Contrast CourtlyLove, IfICantHaveYou, and StalkerWithACrush. See also OppositesAttractRevenge for what this might lead to.

Not related to CatFight, but if [[GenderFlip two girls have mutual interest over the same dude]], they ''can'' get into one. It rarely overlaps with a [[OldSchoolDogfight Dogfight]]. ({{Ace Pilot}}s are too classy for that).

This trope is named for the rooster as a metaphor for a male animal which fights over a mate though the double-meaning is not unintended. For literal animal fights, see BeastlyBloodsports and {{Mon}}. It has at most metaphorical connection with a fight between two male reproductive organs over access or possession of a female reproductive organ.



[[folder:Anime & Manga]]
* ''Manga/InuYasha''. InuYasha and Kōga over Kagome (Creator/RumikoTakahashi count: 1).
* Godai and Mitaka over Kyoko in ''Anime/MaisonIkkoku'' (Creator/RumikoTakahashi count: 2).
* Ranma and Ryōga over Akane in ''Manga/RanmaOneHalf'' (Creator/RumikoTakahashi count: 3). Not that Ranma will ever admit [[SheIsNotMyGirlfriend that he likes Akane that way]].
* Tristan/Honda vs. Duke/Otogi in ''Anime/YuGiOh'', over Serenity/Shizuka.
* An odd and incredibly tragic variation in ''Manga/{{Berserk}}''. The first time Guts and Griffith fought was not (directly) over Casca, but it did mark a turning point as her affections and loyalty shifted from (defeated) Griffith to (victor) Guts. Neither had openly displayed romantic or sexual feelings toward her up to that point. Later, after Guts and Casca had become a couple, Guts and Griffith "fight" again. [[spoiler: It's less a fight and more of a CurbStompBattle as Griffith forces Guts to watch as he [[RapeAsDrama rapes]] his lover Casca. The implication is that it's far more about hurting and humiliating Guts than about any attraction for Casca herself.]] The entire time it's happening, Griffith is staring right at Guts.
* [[MoeAnthropomorphism Greece and Turkey]] in ''Manga/AxisPowersHetalia'' fight over [[HoYay Japan's]] affection, though they're [[AttentionDeficitOohShiny easily distracted]] and not above borrowing a camera and making prints for one another if Japan gets (cute and) angry.
* Narrowly averted in ''Manga/JunjouRomantica''. [[CrazyJealousGuy Akihiko]] was about ready to storm in his brother's room and give him a good punch in every imaginable part of his body when he found out that his brother was 'going to take Misaki from him', had Misaki not held him from going through the door.
* In ''Manga/FullmetalAlchemist'', Edward and Alphonse as children both fought for the right to marry their childhood friend Winry. [[spoiler: Alphonse won]] but Winry rejected them both, saying "[she] couldn't possibly marry anyone shorter than [her]", and she was taller than both.
* This is a subplot of Hayato and Randoll's rivalry in the latter half of the ''Anime/FutureGPXCyberFormula'' TV series as they competed for Asuka's love in the Spanish GP, and at one point, Randoll even made a bet with Asuka that if he wins that race, he gets her kiss (that never came to be).
* In ''Anime/AkazukinChacha'', Shiine and Riiya are constantly squabbling over Chacha, who [[ObliviousToLove remains blithely oblivious]].
* ''LightNovel/AiNoKusabi'' has the two {{Yandere}}s Iason and Guy fighting over the latter's former lover which Iason refuses to let go of.
* Tomoe and Mizuki from ''Manga/KamisamaKiss'' have a pretty intense rivalry over Nanami's attention and affection. Tomoe also has a even worse rivalry with Kurama over Nanami.
* In ''Anime/SamuraiPizzaCats'', Speedy and Guido fight each other over Lucille.
** In the original, Kyatto Ninden Teyandee - Yattaro and Sukashii fight each other over Omitsu.
** In both the original and the dub, this one is eventually resolved by [[spoiler:Speedy/Yattaro giving up on Lucille/Omitsu and hooking up with Polly/Pururun instead.]]
* Half-brothers Kai and Enjouji [[HoYay do this over Ranmaru]] in ''Manga/{{Kizuna}}''. Kai eventually backs off [[spoiler:and falls for his bodyguard Masa.]]
* While she is not the ''sole'' source of their conflict, Mikono is definitely a major reason that Kagura and Amata keep duking it out in ''Anime/AquarionEvol''.
* Happens between [[RichSuitorPoorSuitor Tamahome and Hotohori]] in ''FushigiYuugi''. [[spoiler: In a subversion, it only goes to a direct fight when Tamahome is BrainwashedAndCrazy against his companions. Hotohori later backs off.]]
** And in the ''Suzaku hi den'' novel/OAV's, [[spoiler: Hotohori ''again'' finds himself in a similar predicament when both he and [[SiblingTriangle his half-brother Shu]] show interest in Houki. It ends in tragedy: Houki chooses Hotohori, but Shu ends up dying in the arms of both of them.]]
* Ash's Oshawott and Dawn's Piplup over Meloetta, during the Dawn arc of ''{{Anime/Pokemon}}'' 'Best Wishes'.
** A Phione tried to challenge Ash's Pikachu to a fight over Dawn's Buneary, only for Buneary herself to defeat the Phione. Pikachu was confused about the whole thing.
* Shinji and Riiya in ''Manga/AkazukinChaCha''. They even stomp on each others' toes (literally) in the {{Anime}} trailer!
* A gender-flipped, downplayed, and ultimately averted example occurs in ''[[Anime/RebuildOfEvangelion Rebuild 2.0]]''. [[ChickMagnet Shinji Ikari]], for a small portion of the middle of the second act, has [[UnisexTrope both Asuka and possibly Rei gunning for his affections]] [[ShipperOnDeck (though Asuka is]] ''[[GreenEyedEpiphany certain]]'' [[EveryoneCanSeeIt that she is and that she simply doesn't realize it)]]. The battle ground is [[DownplayedTrope Shinji's]] [[ThroughHisStomach palate]]. [[spoiler: Asuka convinces herself that she's giving her all, but, during the climax of the ''fight'']] [[spoiler: ([[CallBack in a re-do of]] [[Anime/NeonGenesisEvangelion the original]] and [[UncomfortableElevatorMoment awkward]] [[LeaveTheCameraRunning elevator scene]], [[LighterAndSofter though far shorter and with much lower stakes]])]] [[spoiler: Rei, sporting considerably more cuts on her fingers than Asuka, unintentionally reveals that she is the one who's been working harder to please him. [[IWantMyBelovedToBeHappy After seeing this, and confirming that Rei does in fact like Shinji, Asuka surrenders]].]] The outcome is averted [[TimeSkip by]] ''3.0.'' [[spoiler: The Rei of ''2.0'' is either dead or simply absent,]][[spoiler: [[CallBack and Asuka all but states that]] [[Anime/NeonGenesisEvangelion she'd rather die than do]] ''[[DoubleEntendre it]]'' [[UnresolvedSexualTension with]] ''[[WoobieDestroyerOfWorlds him]]''.]]

[[folder:Comic Books]]
* ''ComicBook/XMen''
** A tragic version of this is seen when [[HealingHands Elixir]] and [[TouchOfDeath Wither]] compete over Wallflower. It didn't end well for anyone.
** In the ''ComicBook/AgeOfApocalypse'' AlternateTimeline, Cyclops and Wolverine's fight over Jean Grey was ''gruesome'', with Cyke losing an eye and Wolvie losing a hand.
** In the main continuity, both still fight and squabble regularly over Jean as well.
* In ''ComicBook/{{Excalibur}}'', Nightcrawler got in a very violent fight with Captain Britain over Meggan. Captain Britain ''thought'' he was invoking this trope, but in reality, courtesy of grinding stress, a bout of alchoholism, a curse, and exceptionally poor phrasing on Nightcrawler's part, he overreacted and took a swing at his teammate. Nightcrawler, for his part, was strongly tempted by Meggan, but steadfastly refused to act on it in any fashion.
* Cutter vs. Rayek vying to woo Leetah in the ''ComicBook/ElfQuest'' Trial of Head, Hand and Heart arc. Slightly subverted in that whoever wins, Leetah has the final say. Then re-subverted in that she's Recognized Cutter and ultimately can't fight it.
* Putting [[ComicBook/DisneyDucksComicUniverse Donald Duck, Gladstone Gander, and Daisy Duck]] in the same story is a recipe for disaster... and humor. It's interesting to note that in Daisy's eyes she is "officially" engaged to Donald, and the boys' attempts to impress her romantically either go unnoticed or frustrate her to no end. These stories also tend to play up Donald's bad luck and contrast it with Gladstone's legendary good luck, such that the former is desperately afraid of losing his girl while the latter is desperately trying to win the one thing his luck can't provide. Jealousy, envy, and wacky hijinks all around.

[[folder:Films -- Animation]]
* In ''Disney/TheRescuersDownUnder'', Bernard competes with Jake over Bianca's affections. Though in this case, Jake isn't openly competing with Bernard, just unaware of his relationship status with Bianca.
* Disney/{{Bambi}} and Faline's dance of love through the clouds is rudely interrupted by another stag, resulting in a savage fight.
* In the "Baia" segment of ''Disney/TheThreeCaballeros'', several men (including Donald Duck and Jose Carioca) vie for the affections of singer Aurora Miranda (Carmen's sister). At one point, two men stage a stylized dance-fight, with the animation morphing them briefly into roosters.

[[folder:Films -- Live-Action]]
* In ''Film/TheGreenHornet'', Britt Reid and Kato's argument turns violent after Kato implies he's been with Lenore Case (though it's revealed later that he was more concerned with antagonizing Britt). Despite Kato's CrazyAwesome credentials, it's not the fight you'd expect, especially when it [[WeaksauceWeakness ends.]]
* Lampshaded in the Creator/BlakeEdwards film ''Film/SkinDeep'':
-->''(two naked men in a pitch-black bedroom are both wearing glow-in-the-dark condoms, and discover they're both trying to have sex with the same woman. All we see are two erect phalluses moving around the room. At first, the two of them are throwing stuff at each other, then, they get interested and start swinging their [glow in the dark] dicks at each other)''\\
''(scene change)''\\
'''Man in Bed Answering phone''': Uh, Hello? Yeah? Oh really. Okay, I'll come down and bail you out. ''(hangs up)''\\
'''Wife:''' What happened?\\
'''Man:''' Jack's been arrested.\\
'''Wife:''' What's the charge?\\
'''Man:''' Cockfighting.
* Cleaver and Darcy's hilarious WimpFight at the end of ''Literature/BridgetJones' Diary''.
* Andy and Dwight of ''Series/TheOfficeUS'' "duel" over Angela ([[spoiler:That is, Andy pins Dwight to a hedge with his car while his back is turned]]). In a later episode, when characters are musing over bad past breakups;
-->'''Angela:''' My worst breakup was actually two breakups. Two different men. I was in love with both of them and, when things went bad... they had a duel over me.\\
'''Oscar:''' Yeah, Dwight and Andy, we were here.\\
'''Angela:''' No. This was years ago when I was living in Ohio. John Mark and John David.\\
'''Oscar:''' Angela... you had two sets of different men actually ''duel'' over you?\\
'''Angela:''' I guess I have...
* Inverted in ''Film/TheNextKarateKid''. Ned gets jealous of Julie and Eric hanging out and challenges Eric to a fight.
* ''Film/ThisMeansWar'' is about two CIA agents and FireForgedFriends, Tuck and FDR, using all of the resources at their disposal trying win over Lauren, a woman they both happened to meet on the same night. The fact that there is a very dangerous international terrorist seeking revenge on them for the death of his brother is actually a [[SkewedPriorities distant secondary plotline]] in comparison for most of the movie.
* [[DiscussedTrope Discussed]] for tragic irony in ''Film/{{Irreversible}}''; near the end of the film (which, due to the reverse chronology, happens before the other main events,) Alex's boyfriend playfully says that he "stole" her from a friend of his (with whom they both remain on good terms nonetheless) to which she says that he can't "steal" her because it's always the woman's choice and "(she is) not an object". This comes after the audience has watched her being used as exactly that and having her choice violated in the most brutal way possible during the film's notorious eight-minute rape scene.
* In the 2001 crime comedy ''Film/{{Bandits}}'', bank robbers [[Creator/BruceWillis Joe]] and [[Creator/BillyBobThornton Terry]] both fall in love with the [[ManicPixieDreamGirl slight odd]] but [[{{Adorkable}} adorable]] [[Creator/CateBlanchett Kate]] and [[HilarityEnsues hilariously fight over her in scenes that involve dancing and plate glass windows]]. In a rather surprise twist, [[spoiler:Kate ends up [[OneTrueThreesome choosing both of them]], and they seem to be more than happy to share her.]]
-->'''[[SicklyNeuroticGeek Terry:]]''' Kate, you should choose. What's it gonna be? Mr. Action Figure Hero Guy? Or brains, and sensitivity, and a lot of other things I could name. So in other words: me or THAT guy?
-->'''[[ActionGenreHeroGuy Joe]]:''' Yeah. Good looking or ''ITCHY''?
* ''Film/BackToTheFuture:'' Pretending to fight and lose to his potential father over his potential mother is time traveling Marty [=McFly=]'s plan to make sure his potential parents get together romantically so he and his siblings won't disappear due to never being born. Unfortunately, due to some bad luck the plan goes badly wrong and his potential father gets in a real fight with Biff, a strong and mean spirited bully, while Marty is trapped helplessly in the trunk of a car. [[spoiler: Biff loses.]]

[[folder:Live Action TV]]
* One episode of ''Series/{{Angel}}'' had Wes and Gunn get into a physical fight because they were both in love with Fred.
** Angel and Riley essentially do this on ''Series/BuffyTheVampireSlayer'' in one ep as well. Buffy threatened to hospitalize them if they kept it up.
** Angel and Spike do this over Buffy, just adding one more aspect to their competitive relationship. In ''Buffy's'' "Chosen" they both show their petulant jealous sides, but Buffy is more amused than angry. She eventually tells Spike that one day she's just going to put the two of them in a room and let them wrestle it out. When Spike says that's fine with him, [[GuyOnGuyIsHot her eyes widen in excitement and she says "There could be oil of some kind involved..."]]
* ''Series/That70sShow'': Hyde and Kelso once spent an episode fighting for Jackie's attention. When they get fed up with her jerking them around and tell her to choose, she says she can't. [[TakeAThirdOption Then she chooses herself]].
* ''Series/HowIMetYourMother'': While Robin's dating Don, [[GreenEyedEpiphany Barney decides he wants her back]], leading Ted to the same revelation. They both get blindingly drunk and beat the crap out of each other, then try to drag Don into a three-way cock fight. He declines, because, unlike them, he's sober. And since she's with Don, they both lose. In the long run, [[spoiler:Ted wins]].
* In ''Series/MalcolmInTheMiddle'', Hal and Lois each set their babysitter up with, respectively, Abe and Craig, and she tries to date them both simultaneously until it leads to this. The two guys [[HollywoodNerd being who they are]], though, it's just a furious [[WimpFight slap fight]], and she chooses to dump both of them and "concentrate on her career" (despite having managed to lose the baby in all the excitement).
* In ''Series/TheVampireDiaries'', Stefan and Damon over the affections of first Katherine and then Elena.
* Richard Series/{{Castle}} and Beckett's ex-boyfriend Will Sorensen. Halfway through the episode, Beckett flat-out suggests they just drop their pants and get it over with.
* Parodied in an episode of ''Series/TheBigBangTheory''; when the gang can't agree who gets to ask out Sheldon's sister Missy, they decide to fight over her "[[LetsFightLikeGentlemen the right way -- the honourable way]]"... Wii Boxing. Leonard wins, triumphantly walks over to her door and asks her out... and she flatly turns him down. Leonard muses that that was an outcome they hadn't anticipated.
* The ''Series/TenaciousD'' series features this between Jack and Kyle, and it swiftly turns into a cartoonish kung-fu battle.
* In ''Series/{{Supergirl}}'', Mon-El challenges Mr. Mxyzptlk to a duel (cue Mxyzptlk transporting them to a theater stage dressed as [[Theatre/{{Hamilton}} Hamilton and Burr]]), using an artifact to rob the imp of his power, though Mxyzptlk still has enough SuperStrength to put up a good fight. Kara is not amused.

* Edward and Jacob over Bella in ''Literature/{{Twilight}}''.
* Variation in ''Literature/FriedGreenTomatoesAtTheWhistleStopCafe'': In the book, Ruth's husband fights with Ruth's lesbian lover, Imogen (Idgie), when Ruth says she wants to escape her abusive marriage to live with her.
* ''Literature/ColasBreugnon'' has the protagonist reminiscencing on his young love, which eventually drove him to fight his friend Pinon for her affections, to the death (but nobody died, though there was a lot of bleeding). Both competitors are even referred to as roosters.
* In ''Literature/OurMutualFriend'' by Charles Dickens, a rivalry of this nature springs up between upper-class lawyer Eugene Wrayburn and schoolteacher Bradley Headstone, over Lizzie Hexam. Particularly in Headstone's case, it's debatable whether love for Lizzie or hatred for the other man is stronger.
* In ''Literature/ASongOfIceAndFire'' there was a non-heroic example of this long before the events of the book. Though she eventually married Eddard Stark, as a child Catelyn was betrothed to his older brother Brandon (who died in an unrelated incident) but was loved by a young Petyr Baelish (who would grow up to become the series premiere MagnificentBastard Littlefinger). This rivalry over Catelyn eventually led Petyr to challenge Brandon to a duel for Catelyn, where he got utterly [[CurbStompBattle curb stomped]]. The [[StartOfDarkness resulting effect on his character]] causes no end of problems for the whole of Westeros.
** Also in the back story is the cock fight to end all cock fights. Robert was rather understandably furious when Rhaegar kidnapped/eloped with Lyanna, his betrothed, which then sparked a ''war''. When Rhaegar and Robert finally met at the end of said war, they had an epic battle that Rhaegar fatally lost. Unfortunately for pretty much everyone, Lyanna died anyway.
* AmeliaPeabody finds watching her husband Emerson fight the 'Master Criminal' Sethos for her quite an 'interesting and stimulating sensation.
* In the ''Literature/HarryPotter'' series, this was one of the things that fueled the rivalry between [[spoiler: James Potter and Severus Snape. Both had feelings for Lily Evans, but Snape ruined his chances with her when he called her a racial slur to her face and James ultimately reformed from a bully into an honest man who won Lily's heart the right way]].
* According to Creator/DaveBarry, elk do this until the female leaves in boredom, at which point the winning male has taken so much brain damage he mates with the first thing he sees, including shrubbery.
--> This is the great irony of macho behavior: women never seemed impressed by it.
* ''Literature/JourneyToChaos'': Siron of Esrah and Culmus of Stratos fight each over Princess Kasile. They're so intense about it that they are not allowed to joust each other for fear of "accidents". In the aftermath of a RescueArc, she has to plead with them not to fight each other and even then there's a close call with StabTheScorpion. When they make their DeclarationOfProtection to her, they glance sidelong at each other: "Your Highness is safe with ''me''." This state of affairs is even more depressing for Kasile than the typical version; she confides in Eric, [[LikeBrotherAndSister her surrogate big brother]] that she hoped they would become BashBrothers.

* "Ernie, the Fastest Milkman in the West" plays the trope perfectly straight, but Ernie's rival Ted gets a JerkassHasAPoint moment of LampshadeHanging when he mocks the concept of competing with Suzie as a prize (see page quote).

[[folder:Musical Theatre]]
* Almost happens between Lord Tolloller and Lord Mountararat over Phyllis in Creator/GilbertAndSullivan's ''Theatre/{{Iolanthe}}'', but narrowly averted when Phyllis reminds them of what's important and what's not.

[[folder:Video Games]]
* What makes two people who are friends and comrades in battle fall apart? Being mutual lovers of the same girl. This is the fate of Akihiko Sanada and Ken Amada in ''VideoGame/{{Persona 3}} Portable''. Granted it's only relevant in Tartarus and is optional but oh, those wars. (And Ken is surprisingly able to hold his own, despite being younger than the standard.)
* Played for [[RuleOfCute aww-ness]] in the backstory of Franchise/KingdomHearts, Sora and Riku always compete for Kairi's affection (she supports the friendly rivalry, oblivious to the reason). [[WhamEpisode But things]] [[RivalTurnedEvil don't go]] [[TheUnchosenOne that smooth]] [[KudzuPlot later]]... [[IWantMyBelovedToBeHappy at first]]
* PlayedForLaughs and briefly at that during the romanced Garrus/female Shepard tango scene of the ''Citadel'' DLC of ''VideoGame/MassEffect3''. You can potentially use a Renegade interrupt to make Shepard spin away from Garrus and slide intently up to [[MrFanservice Lt. James Vega]], who is watching the scene take place. Vega makes an approving noise, before Garrus aggressively pulls Shepard back to him.

[[folder:Visual Novels]]
* [[PrincelyYoungMan Arsenik]] and [[HandsomeLech Night]] fight over Ambrosia in ''VisualNovel/War13thDay''. With the way the game's set up, you have to decide whether it's more in-character for her to cheer on Arsenik, protect Night, or [[MultipleEndings do neither.]]

[[folder:Web Comics]]
* An ongoing character arc between Gilgamesh Wulfenbach and Tarvek Sturmvoraus in ''Webcomic/GirlGenius'', both vying for the affections of Agatha Heterodyne and neither holding the other's integrity of character in particularly high regard. Played with at least a couple of times where Agatha has shown herself to be willing and capable of stepping in and kicking ''both'' of their asses just to get them to behave for a while. Of course, given that they are VitriolicBestBuds ''and'' each other's political rivals, they do surprisingly little fighting over Agatha. After all [[ThreesomeSubtext they don't mind Agatha being the boss of them.]]
* Amusingly subverted/lampshaded in ''Webcomic/ErrantStory'', as Jon [[http://www.errantstory.com/2007-05-16/657 interrupts]] a CatFight between his sister and Sarine.
-->'''Sarine:''' Oh, hello, Jon. We were just having a little girl talk. Sweaty, violent, mostly one-sided girl talk with lots of sword fighting.\\
'''Jon:''' ... Ah. Now see, guys don't have those kinds of talks. We just whip it out and see whose is longer.
* In ''Webcomic/TheDreamer'', Alan Warren and Alexander Hamilton often get into snippy fights around each other, often involving Beatrice as the subject.
* ''Webcomic/{{Homestuck}}'' had a bizarre instance of this resulting from culture clash. In short: [[TheNapoleon Karkat]] thinks [[DeadpanSnarker Dave]] is dating [[TricksterArchetype Terezi]], which [[SheIsNotMyGirlfriend Dave denies]]. Karkat also wants to date Terezi, and suggests an unnecessarily complicated form of {{polyamory}} as a solution. Dave is [[NoJustNoReaction mortified]] that they're even having this conversation. Fisticuffs ensue when Karkat tries to draw a diagram of his plan, the boys spend several pages squabbling over a pen, Dave forces Karkat to draw several penises with said pen, and Karkat [[SincerityMode tells Dave]] to [[FoeYay stop flirting with him]].

[[folder:Western Animation]]
* This is the premise of nearly every ''ComicStrip/{{Popeye}}'' cartoon ever made, ever.
* In ''WesternAnimation/TomAndJerry'', Tom and Butch are often in competition over the affection of an attractive female cat.
* Ulrich and William over Yumi in ''WesternAnimation/CodeLyoko''. Actually came to blows in "A Bad Turn"... and that's just the beginning!
* In ''WesternAnimation/BatmanTheAnimatedSeries'', SelfDemonstrating/TheJoker gets into a brief argument with [[AxCrazy the Creeper]] over ownership of Harley Quinn. Subverted in that it's more about "ThereCanOnlyBeOne batshit-insane creep in Gotham City", rather than who is Harley's man.
** Also, Harley only loves the Joker, who's not interested as usual. And it was not until later that the Creeper becomes smitten with her.
* Purposely invoked by Smurfette in ''WesternAnimation/TheSmurfs'' episode "Romeo And Smurfette" when she fell under the influence of Gargamel's hypnotic flower, and she chose Hefty and Handy as her primary suitors, which led them and the whole village into a ShipToShipCombat.
* Played with in ''WesternAnimation/TheAmazingWorldOfGumball'' when Tobias challenges Gumball to a duel for Penny's affections. Gumball initially refuses and only accepts because Tobias would not stop bothering them otherwise. After it starts, Penny flat-out tells Tobias that she won't like him even if he wins and Gumball asks if he'd given any thought to what Penny would think, all of which Tobias is [[SmallNameBigEgo too delusional]] to pay any mind.
* In the [[WesternAnimation/ClassicDisneyShorts Disney cartoon]] "[[WesternAnimation/PlutoThePup Pluto]]'s Heart Throb", Pluto and Butch vie for the affection of a female dachshund named Dinah.
* This is the premise of the ''SouthPark'' episode ''Bebe's Boobs Destroy Society'', with the entire 4th grade class becoming rivals with eachother over Bebe, to the point where they degenerate into cavemen, and physically fight eachother in a massive brawl. In the commentators track for the episode, Parker and Stone mention an incident they witnessed at a party where two drunk guys almost got into an altercation over a girl, but both of them were so drunk that the discourse was done entirerly in grunts and shoving.

[[folder:Real Life]]
* It's often seen during the mating season, between most animals. And yes, that definitely includes humans, for whom every season is mating season.
