History YMMV / FridayNightFunkin

* CrackPairing: Usually, these ships overlap with ShipsThatPassInTheNight for bonus crack points.
** There exists a small following for [[Music/{{Vocaloid}} Hatsune Miku]] and [[spoiler:the Monster]], based on the fact that the two are standing next to each other in the background of Week 5.
** There's a following for shipping Mommy Mearest with Skid's mother Lila from ''WebAnimation/SpookyMonth'', due to them both being [[StacysMom hot MILFS]].
** Pairing Monster with Skid's mother Lila is exceedingly popular, in part from the {{Fanon}} of Monster being friends with and/or acting as a father towards Skid and Pump, in part because the dynamics can range from AngelDevilShipping to DatingCatwoman depending on how one spins the characters.
** Shipping Monster with Senpai is surprisingly popular, especially for those who consider [[CompositeCharacter Senpai and Spirit to be the same character]], due to the utter contrast of Senpai and Monster's designs and both Spirit and Monster being supernatural abominations. Those who don't consider Senpai and Spirit the same character but still ship Senpai/Monster then get the humor of Spirit being confused and disgusted over why Senpai would want to tap that.
** A small following exists for Cassette Girl and [[WebAnimation/MadnessCombat Hank J. Wimbleton]], stemming from them being [[PairTheSpares the remaining two characters]] from the game's initial reveal that have yet to be added to the game proper.

** Many players agree that Week 2 represents a big jump in difficulty. Imagine barely beating "Dad Battle", essentially a rapping boss battle with appropriately fast and frequent notes with instances of harmonizing with your opponent rather than copying them. Now imagine that times two with two spooky boys that don't know how to let up, and The Boyfriend's crotch will be numb with the amount of times he gets blueballed.
** While Week 2's songs were made easier on Easy and Normal upon the addition of Week 4's songs to smooth the curve, Week 4 makes up for it with constantly intense beats and frequent duet parts that can quickly turn your chances with The Girlfriend into roadkill. "MILF" in particular can be described as the craziness of "Dad Battle" but dialed up.

** Despite the increasing number of nods both in-game and [[WordOfGod from the creators themselves]] that the parents are trying to attack and/or kill the Boyfriend, and have done so to others, it's very common for fans to portray them as laid-back but overprotective parents who are wary of the Boyfriend but decide to give him a chance, likely due to SoundtrackDissonance.
** Pico is a hired assassin who recognized the Boyfriend and [[CruelMercy decided to embarrass him in a rap battle instead of killing him]], and is described by ninjamuffin as hating the two despite ultimately sparing Boyfriend's life, but fanwork often depicts him as a "third friend" to the Boyfriend and Girlfriend who regularly hangs out with them. In shipping art, Pico is sometimes depicted being a grumpy {{tsundere}}. However, canon ended up supporting the more heroic ([[SociopathicHero in his own way]]) interpretation of Pico, [[spoiler:when he saves Boyfriend and Girlfriend from being shot by the Tankmen]].
* EvilIsSexy: Both of the Girlfriend's parents are subject to ''a lot'' of SelfFanservice. In Mommy Mearest's case, the devs encourage {{Rule 34}} art of her, and two of her songs are even titled "[[BlackBraAndPanties Satin Panties]]" and "[[StacysMom MILF]]".

** Fanon tends to completely ignore WordOfGod's statement that Pico hates the Boyfriend and Girlfriend, and instead go with the interpretation that Boyfriend and Pico are AmicableExes who hang out regularly, with the latter having lingering feelings for the former. [[spoiler:It helps that he saves the two when Tankman tries to kill them.]]

** It is commonly believed the Boyfriend is the brother of Music/HatsuneMiku, as both are blue-haired singers with an electronic voice. Further fueling the fans are the creators of ''[=Friday Night Funkin'=]'' jokingly calling it canon, as well as Miku making a cameo in the background of Week 5, closer to where Boyfriend's end of the battlefield is.

** In ''[[WebAnimation/FridayNightFunkinWithLyrics Pico & Blammed WITH LYRICS]]'', when the Boyfriend asks why Pico's crossed their path, he responds with "Savin' your bacon. Or cookin' it." [[spoiler:In Week 7, he really does step in to save The Boyfriend's bacon.]]

* MemeticLoser: While most of the fandom depicts Daddy Dearest as the RetiredBadass he is, some picture him as a weak SoreLoser unrivaled by the Boyfriend due to his songs being extremely easy.

* OneTrueThreesome: Following ninjamuffin99 stating that The Boyfriend and Pico used to date, The Girlfriend/The Boyfriend/Pico immediately sprang up in popularity as a happy compromise between the two pairings.

** Sarvente and Ruv from ''VideoGame/MidFightMasses'' have been steadily gaining a foothold in other fan content outside their fan week. While the character dynamics between them and the Boyfriend/Girlfriend couple provide fun enough potential material and the week songs are enjoyable, the thing most people like focusing on is the utterly badass Russian hard-bass style of Ruv's "singing", which fans like pairing up with other fan characters such as Whitty through song remixes, just to hear that bass comboed with other "singing" styles. Even Phantom Arcade mentioned how much he enjoyed "[[https://www.youtube.com/watch?v=e7nIQ1yoCCc Zavodila]]", the song featuring Ruv in the actual mod. Alongside that, their children from another universe, Selever and Rasazy, are also rather popular. Like ''Vs. Whitty'', when ''Mid-Fight Masses'' was taken down following one of the creators being heavily harassed by their newly-acclaimed fanbase, the community mourned.

** Week 6's "Roses" has the point where Senpai grows desperate against the Boyfriend, sending a barrage of arrows in a practically ''unreadable'' pattern near the end. By the point you get there you'll probably have enough energy to survive it, but the final verse has Senpai repeat it again without letting you get much energy to recover before he does. Better have your fingers ready, or you'll have to begin the song ''from the beginning.''

** While all the songs in Week 7 are bangers, it's due to how fast Tankman spits his bars. However, the speed of the songs means that (according to ninjamuffin99) Week 7 is basically the [[ThatOneAttack beatdrop]] in M.I.L.F., but for three songs straight. While "Ugh" [[BreatherBoss starts the week a little more comfortably]] and "Stress" gives the Boyfriend a few [[SuspiciousVideoGameGenerosity opportunities to recover]], [[NintendoHard "Guns"]], the second song of the week, gives the player no such mercy. Tankman frequently spits bars like crazy on ''almost every verse'', and this song is among the fastest songs in the game. What's more, the second half of "Guns" swarms you with what's possibly the longest note sections in the whole game, meaning you'll hardly have any room to catch your breath. Just when [[HopeSpot you think you're safe]], Tankman will occasionally throw one or two quick notes your way ''[[KaizoTrap during his part]]''. To top it all off, this is [[MarathonBoss the longest non-Monster song in the whole game]], clocking in at a brutal ''2 minutes and 20 seconds''. Due to the length and throwing every trick in the book the Boyfriend's way at a blazing pace, "Guns" can make even ''M.I.L.F.'' look like [[FromBadToWorse the tutorial level]].

* TheyChangedItNowItSucks: Some fans aren't happy with the Boyfriend's health bar icon being changed in the Week 4 update, citing that the old one was more expressive and easier to edit for {{Game Mod}}s. Fortunately for fans like them, the original head was still in-game, and the 9 button can be pressed to switch between the old and new icons.

** While Week 2's songs were made easier on Easy and Normal upon the addition of Week 4's songs to smooth the curve, Week 4 makes up for it with constantly intense beats and frequent duet parts that can quickly turn your chances with The Girlfriend into roadkill. "MILF" in particular can be described as the craziness of "Dad Battle" but dialed UpToEleven.

** In Week 7's final song [[spoiler:Girlfriend is carried in Boyfriend's arms while Pico fights off the Tankmen in the background. Additionally, right after she teleports into his arms, she hugs him lovingly and he ''blushes''! D'awww]].

** Week 7's "Guns" has its final section, which appropriately brings an already-tough song to an even harder finish. Once you reach the section, Tankman begins yet another relatively complex pattern...but just keeps on going and going. He spends a whole ''32 beats'' on this part, and [[OhCrap now you have to copy it.]] Even worse, he does this same pattern ''[[RuleOfThree three]] [[UpToEleven times]].'' It hurts especially to end up losing here, too, because Guns is [[MarathonLevel quite the long runner.]]

** "M.I.L.F.", Week 4's final song. It's Mommy Mearest's version of "Dad Battle", except the dial's cranked [[UpToEleven so past eleven that the damn thing snapped off]]. It's faster, more aggressive, and ''way'' more note-heavy than "Dad Battle". Those notes are much more varied too with having to flip between fast-paced hold notes followed by storms of regular notes. You'll also be harmonizing with Mommy Mearest almost constantly, meaning there's hardly a moment to catch your breath, and it's also the first playable song in the game to go on for ''[[MarathonLevel two minutes]]''.

[[spoiler:It helps that he saves the two when Tankman tries to kill them.]]

** Skid and Pump's designs are slightly tweaked for their appearance in the game, most notably Pump's signature square tooth being replaced with his mouth curving at the ends. In fan works, the designs are either combined or fans just go with the originals, even if the context is strictly ''Friday Night Funkin[='=]''.

* CrackPairing: Usually, these ships commonly overlap with ShipsThatPassInTheNight for bonus crack points.

** It's commonly mistaken that Pico was a school shooter/started the school shooting in his game, ''Pico's School'', often by people who discovered him through FNF and haven't played Pico's School or only watched a playthrough of him doing the optional kills. In reality, the actual school shooters are Pico's enemies in his game. [[spoiler:The confusion is referenced in Week 7, where Tankman insults Pico by asking "Don't you have a school to shoot up?".]]

* RecurringFanonCharacter: There have been several fan-created mods where the opponents are either characters from pre-existing properties, or are completely original characters made by the mods' creators. In the case of the latter group, some mod characters become so popular that they spread across the entire fandom, with a few examples being:
** [[VideoGame/VSWhitty Whitty]], a humanoid bomb, is a very popular fanon character[[note]]Although it's a bit more complicated than that[[/note]] due to his incredibly well-done fan week, to the point where it could easily be mistaken as official. As such, he often appears in fanart and memes, and the developers of the base game occasionally retweet art featuring him. Interestingly enough, [[OlderThanTheyThink he was an already existing OC that was around]] before ''Friday Night Funkin[='=]'' was a thing. When his mod was taken down after Whitty's creator left the fandom, the community mourned like he actually died.

** Sarvente and Ruv from ''VideoGame/MidFightMasses'' have been steadily gaining a foothold in other fan-content outside their fan week. While the character dynamics between them and the Boyfriend/Girlfriend couple provide fun enough potential material and the week songs are enjoyable, the thing most people like focusing on is the utterly badass Russian hard-bass style of Ruv's "singing", which fans like pairing up with other fan characters such as Whitty through song remixes, just to hear that bass comboed with other "singing" styles. Even Phantom Arcade mentioned how much he enjoyed "[[https://www.youtube.com/watch?v=e7nIQ1yoCCc Zavodila]]", the song featuring Ruv in the actual mod. Alongside that, their children from another universe, Selever and Razasy, are also rather popular. Like ''Vs. Whitty'', when ''Mid-Fight Masses'' was taken down following the creator being harassed, the community mourned.

* BadassDecay: Many people who knew Pico [[VideoGame/{{Pico}} well before]] ''[[VideoGame/{{Pico}} FNF]]'' were put off by his LighterAndSofter portrayal in Week 3, more specifically, how he challenges Boyfriend to a rap battle instead of shooting him on the spot. The fact that some fanfics portray Pico as a DracoInLeatherPants didn't help matters either, [[spoiler: though his appearance in Week 7 brings him closer to his original portrayal.]]

** It's commonly thought that the Monster is a personified tribute to the one-man band Music/LemonDemon, due to his design (which also vaguely resembles a hornless version of [[https://static.wikia.nocookie.net/music/images/a/af/A-2923813-1381794800-5287.png.jpg/revision/latest?cb=20190812190213 Lemon Demon's logo]]), his [[LyricalDissonance general style of music]], and that some of Lemon Demon's works such as ''Music/TheUltimateShowdownOfUltimateDestiny'' were big on Newgrounds back in the 2000s. However, Ninjamuffin claims that the Monster wasn't directly based on anything, and any similarities are just coincidences, publishing concept art as proof of it. Bassetfilms has also stated that the Monster's songs were actually inspired by Music/TheBlakeRobinsonSyntheticOrchestra. That didn't stop "Lemon Demon" from being adopted as a FanNickname for the Monster though.

* FirstInstallmentWins: A weird example regarding the music. Generally, the music in the game is regarded as memorable regardless of which stage. However, while "Guns" and "Stress" are considered good songs in their own right, they're considered nowhere near as great as [[SpotlightStealingSquad "Ugh"]], which is widely considered to be one of, if not ''the'' best song in the game. A similar argument could be made about "Pico" in comparison to "Philly Nice" and "Blammed", although it's generally agreed upon that "Blammed" is one of the more memorable songs in the game as a whole.

** Ever since ''VideoGame/TheTrickyMod'' released and caused a ColbertBump to the series the titular character came from, mods crossing over with ''WebAnimation/MadnessCombat'' are common. Especially mods of the protagonist of the series, Hank J. Wimbleton, despite being planned to appear in the vanilla game.

** There's a following for shipping Mommy Mearest with Skid's mother Lila from the ''WebAnimation/SpookyMonth'' shorts, due to them both being [[StacysMom hot MILFS]].

** And do ''not'' make the mistake of thinking that FNF stands for ''VideoGame/FiveNightsAtFreddys''.

* ShoutOut: It's possible that "Philly Nice" may be in reference to Kawai Sprite's previous work, simply titled "[[Music/ChuckieFinster Philly]]".

** A decent number of {{Virtual YouTuber}}s and their fans have taken to calling Senpai "Evil [[WebAnimation/{{Hololive}} Roberu]]" after playing the game, due to both being brunette {{Bishonen}}s that possess strong womanizing ways, but with Senpai turning out to be bad news in more than just a competitive way.

** Don't make the mistake of saying that [[WebAnimation/SpookyMonth Skid and Pump]], VideoGame/{{Pico}}, [[WebAnimation/{{Tankmen}} Tankman]], or any of the characters with a {{Crossover}} GameMod originated from ''[=Friday Night Funkin'=]''. This will piss off fans of these characters, who are all [[OlderThanTheyThink older than the game]] (Pico has existed for over ''20 years'' longer than ''FNF'').
** ''VideoGame/VSWhitty'', ''VideoGame/TheTrickyMod'', and other extremely popular {{Game Mod}}s are just that, mods. While some mods may have become nearly as iconic as the main game, claiming that their characters and songs originate from the actual ''Friday Night Funkin''' game will out you as someone who hasn't actually played the game.

* PopularWithFurries: Somehow, despite neither the currently playable game nor the planned full game having any furry characters in them, it has managed to amass an utterly massive furry fanbase. The most plausible explanation for this is that the easily-moddable nature of the game means numerous furry fans are free to create downloadable mods featuring their OCs, e.g. ''VideoGame/VsKapiArcadeShowdown'' (Kapi the Cat), ''Friday Night Gamin''[='=] (Loki the Wolf), and more, all of which draw in even more furries who enjoy said mods and the game itself.

** In ''[[WebOriginal/FridayNightFunkinWithLyrics Pico & Blammed WITH LYRICS]]'', when the Boyfriend asks why Pico's crossed their path, he responds with "Savin' your bacon. Or cookin' it." [[spoiler:In Week 7, he really does step in to save The Boyfriend's bacon.]]

** Further complicating matters, the [=GameBanana=] page for the game disallows any mods containing nudity, despite the game's aforementioned mature themes and the fact that, with a few exceptions[[note]]The pages for several ''Franchise/SonicTheHedgehog'' and ''Franchise/Pokemon'' games, both of which are family-friendly franchises[[/note]], the site ''does'' allow for nudity, provided it's marked as NSFW first and isn't pornographic in nature[[note]]Meaning no sexual acts are to be shown or implied[[/note]].

* MisaimedFandom: Despite the mature themes of the story and a lot of the songs, the game is often [[WhatDoYouMeanItsNotForKids mistaken as being a kid-friendly game]] when it is clearly not.

** There's a following for shipping Mommy Mearest with Skid's mother Lila from the ''WebAnimation/SpookyMonth'' shorts.

** A small following for Cassette Girl and [[WebAnimation/MadnessCombat Hank J. Wimbleton]] exists. It might have been because both of them are unreleased characters that have yet to appear in-game.
* CrossesTheLineTwice: Pico [[spoiler: takes Girlfriend's place as the "metronome" during Week 7's "Stress" by [[MickeyMousing shooting and killing Tankmen to the beat of the music]].]]

* CrackPairing:

* ShipsThatPassInTheNight: There is a small following for, [[CrackPairing of all characters,]] Cassette Girl and [[WebAnimation/MadnessCombat Hank J. Wimbleton]] despite never interacting in any media. It might have been because both of them are unreleased characters that have yet to appear in-game.
