->''"A very good measure of how good your friends are is how much you can insult them without them taking offense."''

They're best friends. You can tell because they bicker LikeAnOldMarriedCouple.

Like a beautiful and delicate snowflake, no two friendships are alike. Unlike the beautiful and delicate snowflake, some friendships break out the [[KillItWithFire flamethrowers]] in the face of this [[TastesLikeDiabetes sickening sweetness.]]

[[OddCouple These]] [[OddFriendship guys]] [[LikeAnOldMarriedCouple bicker]] constantly. They're always [[InsultOfEndearment sniping]] at each other. They [[SnarkToSnarkCombat snark]] relentlessly. They duke it out on equal terms, [[VolleyingInsults hurling insults]] at one another with prejudice. But underneath the verbal fencing is a [[HeterosexualLifePartners rock-solid friendship]] that no SmugSnake could hope to chip at. AFriendInNeed may be needed to make this manifest. Often, they have opposite morals, personalities, or [[ActionDuo fighting ability]] which is presumably the cause of the vitriol (or maybe it's just because they're both [[DeadpanSnarker Deadpan Snarkers]]). Such characters may go for a FriendsAllAlong fight if one is introduced before the other.

This trope can often serve as a warning that something may be wrong as well. When one of the VitriolicBestBuds suddenly stops responding to insults or flinging barbs of their own, the other may pick up on the sudden change in behavior as a sign that [[OOCIsSeriousBusiness something is not right]].

Woe betide any outsider to this unusual 'friendship' who thinks that because one is constantly snarking on the other, it gives the outsider the right to make snide comments about the other as well; usually, they will quickly (and painfully) learn that "[[HypocriticalHeartwarming no one makes fun of him/her but]] ''[[HypocriticalHeartwarming me]]''." This is more a given when the vitriol is mutual between both friends, but in the variation where only one is vitriolic it may be a PetTheDog moment or proof that aw, look: They really ''[[AwLookTheyReallyDoLoveEachOther do]]'' like each other!

Compare AwLookTheyReallyDoLoveEachOther, BelligerentSexualTension, and WithFriendsLikeThese. Contrast with HeadbuttingHeroes, who just cold-out despise each other despite being the best of heroes. Some types of VillainousFriendship have a similar dynamic.

'''NOTE:''' Due to a recent rewrite of this page, many examples will still refer to previous "type one and type two" dynamics. "Type two" is the version of the trope described above, while "type one" is a variation in which only one friend is vitriolic while the other friend is [[HorribleJudgeOfCharacter completely oblivious to the vitriol]] and much, much friendlier. If you come across such an example elsewhere on the wiki, please correct it [[Administrivia/TypeLabelsAreNotExamples to be clear without the type label.]]

[[folder:Fan Fic]]
* In ''[[http://www.tfw2005.com/boards/transformers-fan-fiction/828948-transformers-meta.html Transformers Meta]]'', Barricade and Soundwave are this.
* ''Fanfic/CalvinAndHobbesTheSeries'' remarks on the relationship between its [[ComicStrip/CalvinAndHobbes title characters]] in "The Case of the Rogue Water Balloons":
--> ''But Calvin and Hobbes were still best friends, and that would never change.''\\
''No matter how much one ticked the other off.''
** Hobbes' segment in "Tales of a Tiger" also has the narrator remark on it:
--> "Hobbes, as we all know, is Calvin's closest friend, and not just because [[ThereIsOnlyOneBed they have to share a bed.]] Despite a truckload of arguments and disagreements, Calvin and Hobbes are both dependent on each other. Calvin [[CloudCuckoolandersMinder sometimes to bring Hobbes back down to Earth when he gets too overconfident]] and Hobbes needs Calvin to keep his life interesting. [[ArsonMurderAndJaywalking Oh, and he also needs Calvin for]] [[TrademarkFavoriteFood tuna.]]"
* ''Fanfic/EmpathTheLuckiestSmurf'': Besides the Brainy and Clumsy relationship from [[WesternAnimation/TheSmurfs the cartoon show]], there's Empath and Hefty as well as Hefty and Duncan [=McSmurf=]. Despite Hefty's dislike for both Empath and Duncan, he pretty much knows that they care for him and will stick by him like glue.
* ''Manga/{{Evangelion 303}}'': Misato and Ritsuko have this relationship. They [[http://eva303.smackjeeves.com/comics/1046838/055/ often]] [[http://eva303.smackjeeves.com/comics/1346778/031/ enjoy]] [[http://eva303.smackjeeves.com/comics/2056810/017/ poking fun]] at each other.
* Everyone is this for each other to various degrees in ''Fanfic/StoryOfTheCentury'', especially where L, Light, Misa and Erin are concerned. Inevitable when the first is a DefectiveDetective and SociopathicHero, the second and third are his suspects [[spoiler:(not that he's wrong to suspect them)]], and the fourth is an exchange student who is forced into the story due to [[HeKnowsTooMuch being at the wrong place at the wrong time and subsequently being kidnapped by the first.]] Doubles as AMatchMadeInStockholm. They do share a few tender moments between them, but [[spoiler:[[TearJerker ultimately it ends about as well as you'd think.]]]]
* In FanFic/Gensokyo20XX, Yuuka and Eirin are more less this, as they do spend a bit of time being subtly hostile to each other but are nonetheless on good terms and they do care for each other.
** In 20XXII, we have Kaguya and Mokou. Confirmed that they are roommates.
* The central premise of the ''[[MyLittlePonyFriendshipIsMagic MLP]]'' fanfic ''[[http://www.fimfiction.net/story/166203/unlikely-allies Unlikely Allies]]''. Trixie drags Twilight along on an adventure to save Equestria. Along the way they ''constantly'' bicker with each other over Twilight's need to compensate for something, Trixie's shady past, whether or not Starswirl the Bearded was the father of magic theory or an overrated joke, and practically everything in between... while sneaking into enemy territory, taking down monsters, and fighting the bad guy together. They are clearly enjoying themselves immensely.
* Sunset Shimmer and Twlight Sparkle become this in ''Fanfic/StallionsOfHarmonyVerse''. In their first scene together, they mock and belittle each other, and are clearly academic rivals. [[spoiler: However when their attempt to sneak out of Canterlot and help save Shining results in Sunset assaulting a Royal Guard, Sunset assures Twilight that she'll take the fall for the assault , while Twilight assures her that they ([[MyFriendsAndZoidberg and Moondancer]]) are in this together.]] As the narrative points out, "Friendship is weird."
* In ''[[https://www.fanfiction.net/s/7997729/9/A-Wizard-s-Fairytale A Wizard's Fairytale]]'', Aries Kalgarias (formerly Harry Potter) and Druella Macnair. When questioned by an outsider Aries describes the relationship as a "mutually miserable friendship."
* In ''[[https://www.fanfiction.net/s/8527691/29/An-Incomplete-Potter-Collection The Ashikabi of Fire]]'', Literature/HarryPotter and [[Anima/{{Sekirei}} Homura]] spend most of their time either cuddling up next to each other or getting into fire-enhanced fist fights. Later Harry, Ron, and Hermione all treat each other like this. Hermione's parents approve of anyone who can stay friends with her after they get into a fist fight.

* Buzz and Bud from ''Pinball/NoGoodGofers'' typically harass the player, but they're not above insulting each other from time to time as well.
-->'''Buzz:''' "Don't hit me, hit Bud!"
* Red and Ted from ''Pinball/RedAndTedsRoadShow'' combine this with PlatonicLifePartners.

[[folder:Puppet Shows]]
* JustForFun/StatlerAndWaldorf from ''Series/TheMuppetShow'' aren't averse to taking a break from heckling the show to heckle ''each other''.
** To a lesser extent, there's also Bert and Ernie from ''Series/SesameStreet''.
