[[folder:Princess Bubblegum & Marceline]]
The way [[BadassPrincess Princess Bubblegum]] and [[CuteMonsterGirl Marceline]] act around each other is ''very'' reminiscent of a former couple that had a nasty break-up but still retain some feelings for each other, especially on Marceline's part. Granted, Marceline is pretty flirtatious with everybody, but considering things like Marceline being on FirstNameBasis with Bubblegum (''no one else'' calls her Bonnibel) and almost the entirety of the episode "What Was Missing" ([[EarWorm "I'm gonna drink the red / From your pretty pink face"]]), it adds up.
* Marceline's song in "What Was Missing" is about how much it hurts her that Bubblegum is hostile to her, especially when she has no idea ''why'' she's treating her that way, and for some reason she doesn't understand she still wants to "make up" with her despite the pain and to fix whatever they have. She was on the verge of revealing something incredibly intimate (powerful enough to almost open the door) until she lost her nerve at the very end. Talk about ShipTease...
** After Bubblegum's attempt at a song fails, Marceline taunts her that "she's not as perfect as she thought she was" and has no right to judge her, to which Bubblegum angrily replies that she "never said [Marceline] had to be perfect" (the original storyboard has her add "I just want you to not be so much of a screw up all the time!"). In response Marceline spits at Bubblegum, Bubblegum storms off in shocked anger, and Marceline actually starts ''crying'' (for one of only three times in the entire series) and also leaves. What ''happened'' between these two?
** At the end of the episode, Bubblegum's stolen treasure is shown to be a shirt Marceline gave her which she wears ''as pajamas'' (for comparison, Finn's treasure was a wad of Bubblegum's hair when he was still in full PrecociousCrush mode towards her), a revelation which causes Marceline to ''blush''.
* While not quite WordOfGay, Marceline/PB is supported by character designer Natasha Allegri, who has created quite a gallery of Marceline/PB moments which can be seen [[http://natazilla.tumblr.com/ on her blog]] and [[http://adventuretimewithfinnandjake.wikia.com/wiki/Category:Art_by_Natasha_Allegri on the Adventure Time wiki]].
* Edging slightly closer to WordOfGay, a video on the show's Mathematical promo channel on Website/YouTube definitely reinforced (though not confirmed) the "Bubbline" phenomenon in the "What was Missing" episode. While the video primarily played the idea for mild titillation, it demonstrates there is an appreciation for the pairing "in-house", if nothing else. It was later pulled down and disavowed by the show's executive producer, and it should be noted that the people behind the Mathematical channel weren't part of the actual show crew.
* After "What Was Missing" aired, it's not crazy to look back at "Go With Me" and think Marceline could have purposely been sabotaging Finn's chance to go with Princess Bubblegum.
* In "Burning Low" Bubblegum tries to tell Finn, in an attempt to get him to end his [[PersonOfMassDestruction literally volatile]] relationship with Flame Princess, that sometimes you can't be with the person you love because you have to make personal sacrifices for the sake of greater responsibilities. Coupled with the subject of Marceline's song and how fiercely dedicated Bubblegum is to her work, it's very easy to conclude that she's speaking from personal experience.
* In "I Remember You", Marceline has a brief and rather uncomfortable look when the Ice King begins the second verse of his Bubblegum song, singing about how much he wants to be with her. This was not present in the original [[http://www.scribd.com/doc/110544725/I-Remember-You-Storyboard storyboard]], thus leaving the reaction unexplained.
** A line of dialogue suggests that, at the very least, Marceline is not heterosexual.
-->'''Ice King''': I'll get all the princesses and you can have... whatever it is you're into.
* In "All the Little People" when Finn empties the bag of tiny replicas, for a brief moment, Little Bubblegum is in Little Marceline's arms, until Finn separates them. Later, they can be seen walking off together.
* In "The Suitor", Princess Bubblegum shows pretty much no romantic or physical interest in ''any'' of the potential suitors trying to win her over, all of whom are male. She flat out ''refuses'' to date any of them and only goes out with Braco once to perform an experiment, and goes so far as to make a robot of herself just so that she doesn't have to date Braco. Later Princess Bubblegum explains to Braco that she ''does'' care about him but only in a "queen concerned for her citizens" sort of way in a scene [[DoesThisRemindYouOfAnything that plays out a lot like]] a "SorryImGay" moment. On its own it wouldn't mean much, but it adds greatly to Bubblegum's AmbiguouslyGay status.
* The official ''Adventure Time'' comics have their own hints:
** [[http://s3.amazonaws.com/data.tumblr.com/tumblr_m0vzc9FN041qhr62bo1_1280.jpg This page]] is... very open to interpretation, even ''in'' context.
-->'''Marceline''': I can also turn into a tentacle monster. ''[does so]''\\
'''Bubblegum''': How does that help our situation?\\
'''Marceline''': How does it hurt our situation, though?
** Issue 3 has several moments, such as Bubblegum's worry over a scratch on Marceline's cheek even though everybody at the time is hurt except Bubblegum and Finn. Then there is this line after Bubblegum gives Marceline her crown [[spoiler:so that Marcy can fight the Lich.]]
-->'''Bubblegum''': Marceline! Remember you promised to give me back my crown in one piece!\\
'''Bubblegum''': ...\\
'''Bubblegum''': ''(whisper and worried look)'' Don't get hurt.
** In [[http://images.wikia.com/adventuretimewithfinnandjake/images/d/db/Prv13845_pg10.jpg this page]] in ''Marceline and the Scream Queens'' Issue 4, Marceline clearly looks jealous of Bonnie and Guy's increasing closeness.
** In ''Marceline and the Scream Queens'' Issue 5, [[http://25.media.tumblr.com/tumblr_mdao76eS5Q1rhma7wo1_1280.png when Princess Bubblegum meets Marceline's dad]], it plays out a lot like that dreaded moment when you have to introduce your girlfriend to your parent(s). His "I've heard so much about you!" suggests he realizes Marceline and Bubblegum are very close, and Marceline's response would be a bit of an overreaction if she weren't dating (or hadn't dated) Bubblegum.
** Also in Issue 5, [[http://images.wikia.com/adventuretimewithfinnandjake/images/f/f7/Prv14198_pg10.jpg after Marceline finishes her song]], the crowd cheers. And when she sees Bubblegum clap, she ''blushes''.
** In a rather minor detail, in certain panels one can see that Marceline's red boots have Bubblegum's name affectionately written on them. That implies somethings to say the least...
* Considering {{Gender Flip}}ping, it can be assumed that Prince Gumball and Marshall Lee have a similar past.
** [[http://25.media.tumblr.com/58380335fc96f5e84066fc73578a11fc/tumblr_mjbjn2huDB1qmzy0fo1_r1_500.png One page]] [[http://25.media.tumblr.com/f0ad82737e2db3087a1309c6c6c4fce6/tumblr_mjbjn2huDB1qmzy0fo2_r1_500.jpg from the]] official ''Fionna and Cake'' comics has Fionna complaining that she wasn't invited to Marshall Lee's and Prince Gumball's "Boy's Night". They decide they can't keep secrets from her anymore and ''look like they're about to hold hands.'' Fionna and Cake's reactions prove that the implications were all intentional.
** Their short scene in "Bad Little Boy" just ''screams'' "bitter ex-boyfriends", complete with [[DoesThisRemindYouOfAnything Marshal sucking the pink from Gumball's cream puff]] [[GettingCrapPastTheRadar and throwing white sticky stuff on his face]]. It should be noted that the person telling the story in that episode is ''Marceline'' and it's strongly suggested that the ''Fionna and Cake'' world changes depending on who is telling the story.

[[folder:Lemongrab & Lemongrab 2]]
* Lemongrab and Lemongrab 2 ooze this trope out of their lemony pores from their ''first meeting''. The poking, the Eskimo kisses, the cuddling... and Lemongrab has no problem with walking up to the nude guy and poking him repeatedly. PB explicitly states that she made him for Lemongrab to ''be'' with.
** "Stop by any TIIIME!!!" "But call first!" They say to Princess Bubblegum and the others after exchanging interesting smiles of mutual bliss.
* The ''Adventure Time'' Facebook page described their relationship: "They keep each other company in lemony bliss." They sound like a married couple!
** The "But call first!" line is actually a very common thing for recently married couples to say to in-laws in real life.
* At the end of "You Made Me," for just a brief moment, Lemongrab is shown making [[http://adventuretime.wikia.com/wiki/File:Cute_lemongrab_5.PNG this face]] at Lemongrab 2.
* EVERYTHING about the Lemongrabs in "All Your Fault". The way they speak to each other and their children, the way they bicker about what to name their kids, the promo art; ''Adventure Time'' basically has a gay couple who live together and have a bunch of children.
** There is a FreezeFrameBonus screenshot of Lemongrab's brain, in which his thoughts are visible. One of them refers to a "beautiful lemon man."
* Thomas Herpich, one of the artists on ''Adventure Time'' who wrote "You Made Me" and "All Your Fault," was politely asked to draw a picture of the Lemongrabs for a fan at the 2012 Brooklyn Comics & Graphics Festival. Having been given no other instructions on this vague request, Herpich responded by drawing a picture of the Lemongrabs hugging and smiling... [[http://sphotos-c.ak.fbcdn.net/hphotos-ak-snc7/311281_299606876817451_1503856371_n.jpg and butt naked]].
* The two are the stars of an AdamAndEvePlot. Lemongrab, like Adam, starts off totally alone and the first of his kind. Princess Bubblegum (whom LG calls "Glob", or God in ''Adventure Time'' speak) makes another Lemongrab so he doesn't get lonely, and eventually they have children together and start a whole new civilization.
* Their genderbent counterparts in the ''Fionna and Cake'' comic books acknowledge all of this lemony Ho Yay. Kate Leth, who created the genderbent "Lady Lemongrabs" for the backup story "Sour Candy", drew [[http://kateordie.tumblr.com/post/44663873777/ this self-proclaimed "homoerotic" illustration]] one day before the release of issue 3, Sour Candy's debut. [[http://ask-the-two-earls.tumblr.com/post/44736072454/ The comic itself]] also contains a bit of Ho Yay, too, including vague implications of an anniversary party, hand-holding, and face-nuzzling.
* In the first "Adventure Time Annual" issue, there's a 6-page comic called "Lemon Sea." In the story, the Lemongrabs basically go on a date. They leave their kids at home and go to their own private beach for a picnic.
* "Another Five Short Graybles" both ships and sinks by [[spoiler: having the two refer to each other as brother but also refer to each other as a dad to there fake doll son. Of course one then eats the other, maybe]]
[[/folder]]

[[folder:Others]]
* In "Too Young", Lemongrab (unintentionally) sucks on Peppermint Butler's head, and afterwards smacks his lips a couple of times and says "Mmmm!" to himself pleasantly. Neither of them seemed to mind at the moment.
** Well of course he went "Mmmm." Peppermint is tasty!
* Finn has had a few of these thanks to InnocentInnuendo.
** From "Prisoners of Love":
-->'''Finn:''' There's a big sleepy lava man in our front yard! And he is ''so'' hot!\\
'''Jake:''' Mm-''hmm''... ''(nudges Finn)''\\
'''Finn:''' No--[[ThatCameOutWrong no wait, I take it back]]--I don't mean like... ''sexy'' hot...\\
'''Jake:''' No... you ''do'' mean sexy hot!
** From "It Came From The Nightosphere":
-->'''Marceline''': You can't hurt [[HumanoidAbomination my dad]], you're like an ant to him.\\
'''Finn''': Well this ant's about to get in his pants!\\
'''Marceline''': ''(raises eyebrow)'' [[FlatWhat What]].
** In "Hug Wolf", Finn hints that he has "repressed emotional feelings" for Cinnamon Bun.
* Jake [[GettingCrapPastTheRadar outright stated]] that he has "secret crush" on [[BrokenAce Billy]].
* Finn and Jake themselves have some of this. They're brothers, so it's expected they'd be close, but some things bring it to strange levels.
** From "Gut Grinder":
-->'''Finn''': You ''can't'' be stealing gold in your sleep. '''I watch you while you sleep.'''\\
'''Jake''': What?!? Yo, Finn, that is ''creepy'', man.\\
'''Finn''': I can't help it! I take pictures!
** From "The Silent King":
-->'''Jake:''' Hey, Finn's gonna need a queen. ''([[{{Beat}} beat]])'' I'll do it.
** From "The Eyes":
-->'''Finn''': If you weren't so darn ''handsome'', animals wouldn't always be ''staring at you!''\\
'''Jake''': You're just mad at me for being... ''(smiles) handsome?''
* Ice King's obsession with being Finn and Jake's "friend" is half [[JerkassWoobie pathetic]], and half [[DirtyOldMan thoroughly creepy]]. "Still" is disturbing even by his standards, what with paralysing the two of them and forcing them to perform bizarre activities with him, including cooking them an omelette that he's stuck his foot in (so that "part of [him] will be inside [the two of them]").
** The ending of [[GenderFlip "Adventure Time with Fionna and Cake"]] has [[spoiler:the Gender Flipped version of Finn ''declaring her love for the Ice King''.]]
** The comics have Ice King claim that his and Finn's destinies are cosmically intertwined.
* On the subject of "Fionna and Cake", Fionna spends most of the episode on a date with Gumball, complete with Gumball singing her a romantic song. Except [[spoiler:it was actually Ice Queen in disguise. Fionna went on a date with Ice Queen.]]
** Not to mention that [[spoiler: Ice Queen says that Fionna "[[AmbiguouslyBi keeps all the babes to herself]]". One could ''assume'' that she meant the Princes but babes is generally used to describe women not men]].
* The marauders from "Memories of Boom-Boom Mountain" like to wrestle. And then they like to pet each other. Pet each other raw.
** From the same episode:
-->'''Mountain''': Those men and their disgusting fantastic bodies!\\
'''Jake''': This guy has problems.
* In "Death in Bloom", Death kisses Jake ''on the lips'' to restore his memories, with a ''{{Foot Pop|ping}}'' from Jake.
-->"Kiss of death, ''baby.''"
* The very first gladiator in "Morituri Te Salutamus" (who are later revealed to have been forced to kill their partner gladiator by the Fight King) mournfully yells "Hyperion! My ''love''!", and the other gladiators are all either crying or expressing similar dismay. At the end, after [[spoiler:Finn kills the Fight King]], all the gladiators are paired off, holding hands, and disappear together. It was later [[WordOfGay confirmed]] that all of the gladiator pairs were in fact same-sex couples.
* From "The Monster":
-->'''Lumpy Space Princess''': ''No'', Jessica! Don't cheat on Tony with me!
* In "The Hard Easy" Finn kisses a frog, who turns out to be a buff prince. Complete with bright, sparkly [[HenshinHero magical boy transformation]](!).Plus, he calls Jake "sweetles" at one point.
* Prismo has ''[[AmbiguouslyGay a lot]]'' of this towards Jake. It's mostly one-sided since Jake's too oblivious to notice it at all.
-->'''Jake''': I gotta get that guy a girlfriend.
* "Wizard Battle" has Huntress Wizard competing for Princess Bubblegum's kiss, and was seen cheering after hearing about the prize (WordOfGod insists she was more interested in testing her magic powers against the other competing wizards).
** Also in "Wizard Battle", Abracadaniel gives off a [[AmbiguouslyGay gay vibe]] since everything about him is soft and delicate, his speech included, he uses rainbow magic, is outright repulsed at the idea of kissing Bubblegum, and is shaped like a certain body part. Also when he "wins", he states that he ''deserves'' a kiss (not that he wants it, wording is important).
* Whatever BMO did [[http://i3.kym-cdn.com/photos/images/original/000/475/391/28f.gif here]] in "Jake the Dad". While BMO is mostly in the AmbiguousGender camp, other characters and BMO themself often treat them as male.
** The episode ends with [[MakesJustAsMuchSenseInContext Finn laying on his back, with BMO dancing on his belly and BMO's controller in his mouth]].
* Whole "Davey" episode. With Ice Cream person angrily asking Finn out for a dinner, then telling him that he made him one. And with Davey (Finn in disguise) building a shack together with another Candy Person, and then hanging around together in it.
* Jake eats Meat Man's meat in his sandwich. That night he has a dream about Meat Man, the following morning this exchange happens,
--> '''Jake''': ''([[ThousandYardStare staring out the window]] with a cup of coffee and a blanket wrapped round his shoulders)'' I had a dream about Meat Man... I think I'm going to stop eating Meat Man.
* Bubblegum makes out with her left hand in "A Glitch Is A Glitch", which is later revealed to be sentient and female.
* Bubble proposed to BMO in "BMO Lost", and BMO said yes.
* Towards the end of "The Suitor", [[spoiler:Peppermint Butler has a dark magic spell cast on Braco to make him a "love magnet". It goes horribly right.]]
-->'''Braco''': Did it work? Am I love magnet?
-->'''Peppermint Butler''': Well, I want to have your babies.
** Later at the end of the episode, when Bubblegum tells Peppermint Butler that she sent Braco away, he angrily responds with "You should've given him to ''me''!".
* [[GenderBlenderName Tiffany]] has a rather unhealthy obsession with Jake.
** Hell in "One Last Job" Tiffany actually flat out yells "I LOVE YOU JAKE!". Dosen't get anymore blatant than that.
