The Power Of Love: ZCE. Ordinarily, I would flesh these out as I encounter them, but I can\'t even begin to fathom what this one\'s attempting to allude to. Pre Ass Kicking One Liner: Mabel example is not a one-liner; she\'s responding to Bill\'s verbal setup. Soos\'s example is a Pre Mortem One Liner used to end a fight, not a Pre Ass Kicking One Liner used to begin one. Stan\'s example has the same problem as Mabel\'s; it\'s not a one-liner because he\'s retorting to someone else\'s setup. Also, all of these quotes are improperly indented.


* ThePowerOfLove: Or, the Power of Mabel.
* PreAssKickingOneLiner: Mabel has one in "Sock Opera":
-->'''[[spoiler: Bill Cipher!Dipper]]''': Who would ever sacrifice everything they've worked for just for their dumb sibling?
-->'''Mabel''': Dipper would.
** Soos has one in "Soos and The Real Girl" [[spoiler: Just as he's about to throw the CD which keeps Giffany alive into a burning oven.]]

** Stan gets his turn in "Not What He Seems" after [[spoiler: he is taken in by the government.]]
-->'''[[spoiler: Agent Powers]]''': Sorry, but you've got a flight to catch.
-->'''Stan''': Oh yeah? So do you. *Cue [[spoiler: gravitational anomaly]]*

Pool Scene: The involvement of a pool isn\'t what this trope is about. It\'s specifically describing a brief fanservice scene to let the audience ogle women in bikinis. The full-episode variant is a trope unto itself: the Beach Episode. Despite the name, Pool Episodes fall under Beach Episode as well.


* PoolScene: "The Deep End" is a whole pool episode.

Phoneaholic Teenager: ZCE. Pinball: Pinball is a Work, not a Trope. Pint Sized Kid: The trope is fine and well-explained, but the backhanded defense of the Wendip ship is unnecessary. Plucky Girl: ZCE. The Pollyanna: Don\'t subbullet tropes. The Pollyanna describes a character who remains unnaturally chipper and optimistic even in the face of dire negativity. Mable\'s not quite so fervent and has allowed chinks in her optimism to develop under the weight of intense hardship, such as when she wanted to erase her memories of her failed crushes. Police Are Useless: ZCE. What passes for context in this entry is a tongue-in-cheek reference to the context of a different Work that fails to explain how the trope is used in either.


* PhoneaholicTeenager: Tambry

Papa Wolf: ...not sure why this needs to be spoilered. That Stan will protect his family at all costs is general character behavior, not unlike Mabel wearing different sweaters or Dipper being obsessed with the Journals. Perpetual Smiler: Despite her upbeat nature, Mabel has a wide range of expressions and has never so much as gone an entire episode with a smile permanently embedded on her face. Bill, as noted in the description, doesn\'t even have a mouth except when he was Bipper, during which time he wore the Cheshire Cat Grin when he was taunting Dipper, but grimaced at Grenda and quickly dropped the grin in exchange for a menacing frown when intimidating Mabel.


* PapaWolf: Despite not actually being their papa, [[spoiler: Stan does ''not'' take it well when his great niece and nephew are threatened]].
-->[[spoiler:[[HypocriticalHeartwarming The only wrinkly monster who harasses my family is]] ''[[CrowningMomentOfAwesome me]]''!]]

** In the episode "Into The Bunker," Dipper manages to somewhat to confess to Wendy, who knew it all along and while being flattered, lets him down easy to continue being friends. The sinking cements itself in "Blendin's Game" when Dipper realizes (from the other side of their age gap, due to time travel) just how awkward the whole thing might have been to Wendy. However, he hasn't let his feelings go entirely, musing that he should go back to obsessing over Wendy again when he's stuck playing a tabletop RPG with Gompers in "Dungeons, Dungeons and More Dungeons".

-->[[spoiler:[[HypocriticalHeartwarming The only wrinkly monster who harasses my family is]] ''[[CrowningMomentOfAwesome me]]''!]]
* ParentalBonus: '''Loads'''. So much so that it's considered one of the most ParentalBonus-ridden shows Disney has aired in a long, long time. See GettingCrapPastTheRadar and ShoutOut for more details.
* ParentalSubstitute: Stan became one of these for Soos after [[spoiler:his dad skipped town on him.]]
* PerpetualSmiler: Mabel. Whenever she stops smiling, it means that the shit has ''really'' hit the fan.
** Bill Cipher, despite [[EldritchAbomination not having a mouth]], seems to be this due to his constant [[FauxAffablyEvil perky and amiable tone of voice]]. Sure enough, [[spoiler:when he possesses Dipper's body in "Sock Opera", he is almost always sporting a [[CheshireCatGrin huge, demented grin]].]]
* PetTheDog: Grunkle Stan gets a moment like this after feeling guilty for insulting Dipper and Mabel and lets each of them take anything they want from the Mystery Shack. In true Grunkle Stan fashion, he tells them to do it before he changes his mind. He also saves Waddles because he wants Mabel to talk to him again and in "Dreamscaperers" when we find out why he's so tough on Dipper.
* PhoneaholicTeenager: Tambry
* {{Pinball}}: Featured in "Soos' Really Great Pinball Story".
* PinkGirlBlueBoy: Dipper wears a blue and white hat and a blue vest; Mabel isn't as consistent but frequently wears pink/purple/red clothes.
* PintSizedKid: Every kid in the series, major and minor. It makes Dipper's PrecociousCrush on Wendy seem more unnatural than it actually is.
* PluckyGirl: Mabel.
** ThePollyanna
* PointlessBandaid: Old Man [=McGucket=] has one on his beard.
* PokemonSpeak: Shmebulock the gnome.
* PolarOppositeTwins: Smart and conventional Dipper and energetic optimist Mabel. [[http://media.tumblr.com/tumblr_m6gb9txiKW1r9r3hw.gif This image]] best shows their dynamic.
* PoliceAreUseless: Constantly. They actually make [[TheSimpsons the Springfield police]] look competent.
* PoliceCodeForEverything: An officer about to fit a cantaloupe in his mouth is a "23-16", and a citizen delving into the true story of the town's origin is a "Code Sepia".
* ThePollyanna: Mabel often verges on this, but the first true example is during the episode "Not What He Seems". Throughout the entire episode, she simply ''will not'' accept the possibility that [[spoiler:Stan is hiding villainous intent from them]], despite the evidence continuing to pile up more and more as the story goes on. [[spoiler:She very nearly breaks during the climax, but in the end, it's her optimism and faith that manages to get back the Author.]]
* PoolScene: "The Deep End" is a whole pool episode.

* ThePowerOfLove: Or, the Power of Mabel.

-->'''[[spoiler: Bill Cipher!Dipper]]''': Who would ever sacrifice everything they've worked for just for their dumb sibling?

-->'''[[spoiler: Agent Powers]]''': Sorry, but you've got a flight to catch.
-->'''Stan''': Oh yeah? So do you. *Cue [[spoiler: gravitational anomaly]]*
* PrecociousCrush: Either {{Subverted|Trope}} or {{Downplayed}} with Dipper's crush on Wendy. He's 12 and she's 15, making them only three years apart from each other. [[spoiler: Though for the time being, those three or so years are still too much.]]
* ProperlyParanoid: [[spoiler:The old coot was right to be worried about the wax figures.]]
** The FBI is correct in believing that [[spoiler:Stan has built a doomsday device. However, Stan doesn't want to use it to destroy the world, but to save his brother.]]
* PsychicPowers: Li'l Gideon. Until Mabel destroyed his amulet.
* PteroSoarer: The "pterodactyl" from "Land Before Swine", which looks like an unholy mixture of all stereotypes, down to the scaly skin, being called a "dinosaur", having eagle-like hindlimbs, leathery wings, having a ''Pteranodon'' crest alongside rather mismatched teeth, making chicken-like nests and [[ArsonMurderAndJaywalking having zero to no body fat]]. Strangely enough, though, it walks quadrupedally, like a real pterosaur.
* PunBasedTitle:
** From Season 1, there's "Headhunters", "The Hand That Rocks The Mabel", "Double Dipper", "Irrational Treasure", "Little Dipper", "Carpet Diem", and "The Land Before Swine".
** From Season 2, there's "Sock Opera" (played with "Rock Opera" and "Soap Opera"), "Soos and The Real Girl" (ShoutOut to ''Film/LarsAndTheRealGirl''), "Scary-oke" (Homophones of "scary" and "karaoke" together) and "The Golf War" (Play on ''UsefulNotes/TheGulfWar'').
** Mabel's story "Trooth Ache".
** Averted and {{lampshaded}} with Soos' story: [[LongTitle "Soos' Really Great Pinball Story: Is That A Good Title? Do They Have to Be Like Puns or Whatever?"]]
* PunchCatch: [[spoiler: Dipper catches Gideon's fist during their fight in "Gideon Rises". He then twists his hand around and punches Gideon with his own fist.]]
* PunnyName:
** Gravity Falls itself.
*** Lampshaded; it was discovered and named after its [[spoiler:true]] founder rode over a cliff.
** The Gravity Falls gossip reporter is named "Toby Determined".
** The waitress's name is "Lazy Susan". On the surface, she's called this because she has a lazy eye and is named "Susan", but it can also refer to a table surface that spins.

*** It's also possible that his name is a play on the [[http://en.wikipedia.org/wiki/Beale_ciphers Beale Ciphers]].
** Gideon Gleeful
* QuestionableConsent: One point of contention with the episode "The Love God" is over whether or not Mabel using a love potion to make [[spoiler:Robbie and Tambry]] start dating was ethical. See GravityFalls/{{Headscratchers}} for more details.
* RaptorAttack: The raptor from "Land Before Swine". Like the PteroSoarer from the same episode it is guilty of possessing all pop-culture stereotypes: oversized, lack of feathers, pronated hands, and reptilian eyes. It also has two-fingered hands, a feature that doesn't correspond to any known deinonychosaur.
* RapunzelHair: Mabel, Wendy and Pacifica all sport hair that reaches below their waist.
* RatedMForManly: The manotaurs are a race of AlwaysMale half-man half-bulls devoted to this trope. Goes into TestosteronePoisoning territory.
* RealAfterAll: [[spoiler: At the end of "Legend of the Gobblewonker," Dipper's camera falls overboard and we get a shot of the real Gobblewonker.]]
* RealityWarper: In "Dreamscaperers", Dipper discovers that he can do anything he can imagine while inside a dream.
* RealityEnsues: As it turns out, [[spoiler: Wendy knew Dipper liked her all along because she could hear him muttering things about it under his breath. While he was right next to her.]]
** When Gideon takes over the Shack, Stan's awesome battle plan is... to send the twins back home because he can't take care of them anymore. "Summer's over," as he puts it.
** Also, after [[spoiler: Stan beats a horde of zombies back to death and bursts into the barricaded attic, his first words are "Auugh- everything hurts."]]
** When Stan [[spoiler:gets arrested in "Not What He Seems"]], where are the twins taken? [[AdultFear Child services]]. No wacky relative, no vague "you're gonna stay with us", their destination is explicitly identified as "child services".
* ReallyGetsAround: G-Rated example, but Wendy definitely has a hefty list of ex-boyfriends, considering she's only 15.
* RecurringExtra: The cute biker.
** The goat and the woodpecker.
*** Everyone who lives in Gravity Falls, like Lazy Susan, Wendy's friends, Toby Determined, and Manly Dan, to name a few.
* RedheadInGreen: Wendy.
* RedHerring: Both [[spoiler: Manly Dan]] and [[spoiler: Toby Determined]] in "Headhunters." Also, [[spoiler: The Laptop]] in "Into the Bunker" and "Sock Opera".
** There were ''so'' many hints dropped that [[spoiler:Old Man [=McGucket=]]] is the author of the journals that a good number of fans accepted it as canon. [[spoiler:He's not, he just worked with him.]]
** "Northwest Mansion Mystery" heavily implied [[spoiler: Bill Cipher was behind an impending calamity. At the end of the countdown, he's nowhere to be seen.]]
* TheReveal: In "Not What He Seems", we finally find out who the author of the journals is; it's [[spoiler: Stan's brother.]]
* RidiculouslyCuteCritter: Mabel's beloved pet pig, Waddles.
* RichBitch: Pacifica Northwest. [[spoiler: Turns out the [[JerkassFacade "bitch" part is just an act.]]]]
* RightForTheWrongReasons: Dipper thinks that Mabel's new boyfriend isn't normal and he's a zombie. He was right that Norman isn't normal, but [[spoiler:he's actually a bunch of gnomes.]]
* RingAroundTheCollar: Mabel always wears some colorful turtleneck sweater, whose oversized collar obscures most of her neck. Dipper's vest has its collar turned up, which serves a similar effect, even though more of his neck is visible.
* RivalsTeamUp: [[spoiler:Mabel and Pacifica team up against the Lilliputtians in "The Golf War".]]
* RoomFullOfCrazy: Downplayed when [[spoiler:[=McGucket=]'s memories are finally exposed. The room he's seen standing for most of them gradually gets more and more demolished as his SanitySlippage progresses, with the words "HELP ME" eventually showing up in (hopefully) red paint. It's the only one shown, but it's very big and we don't get to see very much of the room, implying this trope.]]
* RubiksCubeInternationalGeniusSymbol: The "What-The-Heck-A-Hedron" is essentially a very hi-tech Rubik's Cube, [[FreezeFrameBonus from the makers of "Stresseract" and "Annoyangle"]]. [[spoiler: it eventually gets solved by a hyperintelligent Waddles.]]
* RunningGag: There are a couple of potential running gags, like Grunkle Stan being unable to find his pants and Manly Dan beating something up while the Cute Biker cheers him on.
** We have:
*** Dipper dropping ice that he gets for Wendy.
*** Dipper's hat catching fire.
*** Woodpeckers.
*** The Dipper and Mabel look-alike kids.
*** Effigies of Grunkle Stan getting destroyed, usually through burning.
*** Someone describing what they are doing in a sing-song voice.
-->'''Soos:''' Doo doo doo, walking to my car~ (2x05)
-->'''Stan:''' Putting a rainbow wig... On a big white gorilla~ (2x09)
*** A human or humanoid scampering away on all fours. Some examples include the gnomes in "Tourist Trapped", and Old Man [=McGucket=] in a later episode.
* RushedInvertedReading:
-->'''Stan:''' Whatcha readin there slick?
-->'''Dipper:''' (hides the journal and grabs a magazine) Oh, I was just catching up on-"Gold Chains for Old Men Magazine?"
-->'''Stan:''' That's a good issue.
* SarcasmBlind: Mabel and Soos have both displayed shades of this trope.
* SassyBlackWoman: Not a literal case of this trope, but after Grunkle Stan drinks the voice altering potion he ends up sounding like one.
* SatelliteCharacter: The cute biker started off as one to Manly Dan.
* SavvyGuyEnergeticGirl: Dipper and Mabel, respectively.
* SayingSoundEffectsOutLoud: Mabel does this on a fairly regular basis, as do other characters.
** "Tourist Trapped":
--->'''Dipper and Mabel, during their "awkward sibling hug"''': Pat, pat.
** "Dipper vs. Manliness":
--->'''Stan:''' Tap, tap.\\
''(later)'' '''Lazy Susan:''' Wink!
* SceneryPorn: It's especially evident in the opening theme, but Gravity Falls is beautiful.
* ScoobyDooHoax: Played straight [[spoiler:in Episode 2, with the Gobblewonker]]. Even this straight example is subverted in the final moments of the episode suggesting that there really is a creature, but it just hasn't been seen (yet?). Otherwise averted in most other episodes, with the monster or ghost proving to be very, very real.
* ScrewPolitenessImASenior: Grunkle Stan, all the way.
* SecretCircleOfSecrets: [[spoiler:The Blind Eye Society.]] They have the ability to [[spoiler:erase people's memories]], and they're the main reason [[spoiler:everybody in town is so [[{{Muggles}} ignorant to all the unusual happenings going on]]]].
* SecurityBlanket: Sweater Town.
** In "The Time Traveler's Pig", Robbie closes his hoodie over his face and continues moping around the fair that way in the timeline where Dipper successfully wins the stuffed panda/duck for Wendy
* SelectiveEnforcement: Blubs and Durland will ignore a man snatching an old lady's purse right in front of them, but are quick to respond to reports of excessive giggling.
* SelfServingMemory: In "The Land Before Swine", when Stan tells Mabel how [[spoiler: the pterodactyl managed to steal Waddles]], the details were somewhat off.
* SenseFreak: Bill becomes one in "Sock Opera", with a focus on pain because he finds it "hilarious!".
* SensitiveGuyAndManlyMan: Dipper is the sensitive guy to Grunkle Stan's manly man.
* SeriousBusiness: Mr. Poolcheck puts a lot of angry violent determination in making pool time safe. He, and a bar of angry men, also don't take kindly to prank calls.
* SetRightWhatOnceWentWrong: In "The Time Traveler's Pig" Dipper tries to win a toy for Wendy at the fair, while at another stall Mabel delightedly wins Waddles the pig. Unfortunately Dipper only succeeds in hitting Wendy in the eye with a ball, causing her to go off with Robbie. After obtaining the time machine Dipper makes several attempts to return to the past and prevent the accident, [[YouCantFightFate only for it to keep happening in different ways]]. Eventually Dipper figures out how to make the ball miss Wendy and hit the target, but Mabel has to be there to help him, so she isn't there to win Waddles and Pacifica wins him instead. Seeing how unhappy this makes Mabel, Dipper realizes he has no choice but to go back and restore the original timeline.
* SheetOfGlass: Parodied in "Legend of the Gobblewonker," when they fly through a pane of glass held between two boats on a lake.
* TheSheriff: Sheriff Blubs.
* ShipSinking:
** Wendy breaking up with Robbie in "Boys Crazy" is one. [[spoiler: It sunk even more after "The Love God", in which Robbie became an OfficialCouple with Tambry.]]
** In the episode "Into The Bunker," Dipper manages to somewhat to confess to Wendy, who knew it all along and while being flattered, lets him down easy to continue being friends. The sinking cements itself in "Blendin's Game" when Dipper realizes (from the other side of their age gap, due to time travel) just how awkward the whole thing might have been to Wendy.
** Those who were fond of Mabel/Mermando [[spoiler: felt their hearts sink when "Society of The Blind Eye" revealed that Mermando is forced into an arranged marriage with a manatee princess for political purposes. Memando himself is clearly unhappy about this based on the photo sent.]]
* ShipTease: Candy hanging on to Dipper after the Trickster's threat in "Summerween" was enough to send some shippers into fits of [[{{Squee}} squeeing]]. There were already Candy/Dipper shippers before, but this was the first real interaction that was remotely shippy they could latch onto, with the subtle peek that Mabel would have tried this with them, might just get larger.
** A ''lot'' between Dipper and Pacifica in "Northwest Mansion Mystery", especially the part when she [[spoiler: hugged Dipper out of joy when they sealed the ghost within the mirror. [[{{Adorkable}} Their reaction afterwards sells it.]]]]
* ShirtlessScene: Dipper in "Dipper vs. Manliness."
** Soos takes off his shirt rather often, and in "Stan's Tattoo", he tries to get Stan to do the same. [[FanDisservice Stan is disgusted]].
* ShoutOut: Has [[ShoutOut/GravityFalls its own page]].
* ShovelStrike: Soos gives a shovel to Dipper in the first episode when Dipper races off to save Mabel from [[spoiler:the gnomes]]. [[CrazyPrepared He also gives him a baseball bat in case he sees a pinata]].
* ShowWithinAShow: Many, including ''Duck-Tective'', ''Tiger Fist'', ''Why You Ackin So Cray-Cray?'', ''Baby Fights'', ''Cash Wheel'', and ''World's Most Terrifying Skydiving''.
* ShownTheirWork: The SceneryPorn of the opening scene, as well as many of the show's backgrounds, is very accurate to actual Oregonian landscape.
** Similarly, almost every real-life animal seen living wild in Gravity Falls is actually native to Oregon, including the [[SeldomSeenSpecies somewhat obscure purple finch]]. See MisplacedWildlife for exceptions.
** The goat that lives near the mystery shack has rectangular pupils, just like goats in real life.
** In ''Northwest Mansion Noir/Mystery'', the mudslide [[spoiler: that killed the lumberjack]] was the result of the deforestation that ensued from [[spoiler: him building [[DeathByIrony the Northwest mansion]] ]]. Deforestation can cause mudslides, because the lack of trees destabilizes the soil, so whenever it rains in a treeless era, the ground becomes saturated and slides.
** For all the stereotypical paleontological inaccuracies present in "Land Before Swine", the episode did get quadrupedal pterosaurs right and portrayed ''Ceratosaurus'' with laterally-flat horns.
** The beavers from "Legend of the Gobblewonker" have yellowish teeth like real beavers.
* ShrinkRay: Dipper makes one out of magic crystals and a flashlight.
* SiblingSenioritySquabble: According to [[http://24.media.tumblr.com/tumblr_m7lhj2iSkz1r9betso1_1280.jpg Word Of God]].
* SignsOfDisrepair: The Mystery Shack's sign regularly loses the second "S" to spell out "Mystery hack", including in the opening theme. Rather fitting considering Grunkle Stan's personality.
* SilenceIsGolden: Each episode plays a short clip over the credits to wrap things up or get in another quick gag before it's over. The episode "Not What He Seems" just shows [[spoiler: two young boys quietly sitting on a swing set, with but the quiet beach breeze for company]]. Especially effective because of [[WhamEpisode what immediately preceded it.]]
* SingleTargetSexuality: Dipper seems to only have eyes for Wendy, though it's {{justified}} since his LimitedSocialCircle makes her the only girl he hangs out with for any length of time other than his sister.
** Though, in the episode "Little Mystery Shop of Horrors", he first gets interested in trying to solve the What-The-Heck-Ahedron when he finds out that anyone who solves it apparently gets their picture taken and a kiss from a hot chick. Then again, that episode's canonical status is up to debate.
** This is up to debate due to ambiguity, but [[spoiler: it's a possibility that this trope has gotten averted what with the vague hints that Dipper may be starting to feel something towards Pacifica in "Northwest Mansion Noir".]]
* SitcomArchNemesis: Robbie to Dipper, Pacifica to Mabel, Gideon to Stan. [[spoiler: Though Gideon eventually becomes the BigBad of the first season, and Pacifica and Mabel have settled their differences.]]
* SkeletonKey: The President's Key can open any lock in America.
* TheSlacker: Wendy Corduroy.
* SlapstickKnowsNoGender: Just because Dipper is our resident ButtMonkey doesn't mean any of the other characters are safe.
* SlidingScaleOfComedyAndHorror: Interestingly enough, the show shows shades of the comedy dominant variety. While the show mostly treats itself like a straight-up comedy, the premise of each episode frequently deals with the supernatural, with some containing scenes so creepy [[WhatDoYouMeanItsForKids that you have to check periodically that you're watching a Disney show.]]
* SlumberParty: Mabel has one with Candy and Grenda in "Carpet Diem".
* SmittenTeenageGirl: Mabel, with every [[GirlOfTheWeek Guy of the Week]] that comes along.
* SmokeOut: Grunkle Stan's preferred exit method.
* SociallyAwkwardHero: Dipper, especially in comparison to [[TheSocialExpert his sister]].
** Soos, especially [[CannotTalkToWomen when he's around women]].
* SomedayThisWillComeInHandy: When Dipper finds the book in the first episode, he sees an amulet but ignores it and continues flipping through the book. Later on, in the fourth episode, it is revealed that [[spoiler:the amulet grants the wearer mystical powers]]. Dipper hasn't realized this yet, however.
* SomethingOnlyTheyWouldSay: A physical variation. [[spoiler: When Wendy is wrestling against a shapeshifter disguised as her in the climax of "Into the Bunker," Dipper asks for a sign. The shapeshifter winks, while Wendy mimes zipping her lip and throwing away the key, a special sign she and Dipper have had since "The Inconveniencing." Earlier in the episode, when Dipper and Wendy run into Soos and Mabel, Dipper initially worries that they might be the shapeshifter. Their goofy antics convince him they aren't.]]
* SomethingThatBeginsWithBoring: Mabel tries to start a game of "I Spy" in a dark and empty bottomless pit.
* SourOutsideSadInside: Beneath his JerkAss persona, [[spoiler:Robbie is actually very insecure and lonely]]. After he's hit rock-bottom, [[AllLovingHero Mabel]] picks up on this and makes it a personal goal to try and cheer him up, [[spoiler:which succeeds, leading him to [[TookALevelInKindness Take A Level In Kindness]]]].
* SpaghettiKiss: Apparently Old Man [=McGucket=] had one with a raccoon over a piece of meat they were fighting over.
* SpitTake: Sheriff Blubs and Deputy Durland spitting hot coffee into each other's faces.
** They {{lampshade}} it, too.
--> '''Blubs:''' I'm so confident you're going to say no that I'm going to take a long, slow sip from my cup of coffee.
** Stan does one and [[BetterThanABareBulb lampshades]] it in "Boyz Crazy."
*** And in "Fight Fighters" after Mabel sneaks up behind while he relaxes in his armchair.
* SpoilerOpening: Paying attention to the part with the photos in the opening shows [[spoiler:Gideon, the gnomes, Blendin Blandin, and the Summerween Trickster. Following this is a split-second image of Bill Cipher.]]
* SpoofAesop:
** In "Summerween", Stan learns to focus on what is truly important in life: ''pure evil!''
** In "Love God", Stan learns that being loved is overrated and being feared is priceless.
* StableTimeLoop: Happens in both of the [[TimeTravelEpisode Time Travel Episodes]].
** "Time Travelers Pig": Blendin Blandin is sent from the future to SetRightWhatOnceWentWrong by cleaning up temporal mess that was apparently started by the twins. He ends up running into them by accident, and after a series of events, the twins end up stealing his time machine. Their misuse of said time machine is what causes the mess that Blendin was supposed to clean up.
** "Blendin's Game": At the beginning of the episode, Soos teaches the twins a trick on how to get free snacks out of a snack machine. After going back in time, [[spoiler: Mabel ends up teaching the same trick to a 12-year-old Soos.]]
** Also in play in both episodes regarding Stan's red screwdriver. Blendin stole it during "Time Traveler's Pig" in order to fix his time machine, and had kept it until "Blendin's Game," where he accidentally drops it in Soos' yard, which prompts him to go to the Mystery Shack and get hired by Stan in the first place.
* StageWhisper: Because he CanNotSpitItOut that he has a secret crush on Wendy, Dipper just tends to mutter about it to himself instead, while still at a distance that she could likely hear. [[spoiler:Subverted, as Wendy eventually tells him she knew all along, partly because of how obvious he was about it]].
* StalkerWithACrush: Lil' Gideon, BIG TIME.
** [[spoiler:Giffany]] is ''[[UpToEleven even worse]]''.
* StalkingIsFunnyIfItIsFemaleAfterMale: Subverted with [[spoiler:Giffany]]. There are points in the episode where her [[spoiler:relentlessly stalking Soos]] is played for comedy, but it's not because she's a girl and he's a guy; it's because [[spoiler:[[KissMeImVirtual she's a computer program and he's a human]]]]. The stalking is otherwise depicted as very serious and disturbing. Soos himself notes the situation is one big red flag, but he's so happy for the attention he goes along anyway.
* StatusQuoIsGod:
** In "Boss Mabel", Mabel makes a deal with Stan to be the Mystery Shack boss for 3 days and if she makes more money in that time, she becomes the boss for the summer. [[spoiler:When Stan returns with no money, she declines after realizing how hard it is to be the boss.]]
** In "Carpet Diem", Dipper and Mabel fight for the newly discovered room to get away from each other. [[spoiler:Dipper convinces Stan to let him have the room, but both Mabel and Dipper miss rooming together, so they give the new room to Soos to replace his horrible break room.]]
*** [[SubvertedTrope Subverted]] by the fact that later shorts show that [[spoiler: Soos does in fact keep the new room. It doesn't go away and get completely forgotten after its discovery]].
** Double subverted in the last two episodes of season 1, in "Dreamscaperers"[[spoiler:Gideon successfully get the the deed to the Shack and the Pines are forced to live at Soos's grandma's. However in the next episodes, Dipper defeats Gideon and everybody can go back to the shack]].
** Averting the trope is a general theme of the series: Dipper getting his new hat in "Tourist Trapped" was meant to be a subtle indication that when things change, they actually change.
* StealthInsult: In Episode 4 of the first season, Dipper gets away with an epic one when he says this to [[RapunzelHair Mabel]] about [[AnimeHair Gideon]]:
--> '''Dipper''': "''I don't trust anyone whose hair is bigger than their head.''"
* StealthPun: "Will you join us in holy matrignomey...matri-matriMONY, BLAH, can't talk today..."
** The wax figures are cursed to come to life whenever the moon is waxing.
** Dipper spends a good amount of time at Mabel's sock puppet RockOpera as essentially a ghost. In other words, he's a literal [[Theatre/ThePhantomOfTheOpera Phantom of the Opera]].
** Sev'ral Timez's producer...actually ''produces'' them as clones.
* StockNessMonster: The Gobblewonker.
* StockPunishment: Grunkle Stan gets subjected to it in "Irrational Treasure."
* StylisticSuck: The "Fixin' it with Soos" shorts. Soos claims to have edited them himself, and they're rife with badly animated clip art and lousy green screen effects. The "Gravity Falls Public Access TV" shorts also get it on it, showing a Mystery Shack TV ad with lousy editing and green screen footage.
** Several of his computer graphics shots have a watermark of the free trial software he uses to make his segments.
* SubliminalSeduction: [[spoiler: Due to Robbie's song containing hidden backwards messages.]]
** Possibly subverted, as it's not clear if it actually worked. Wendy says afterwards that [[spoiler: she doesn't care about the messages and she mainly seems to be upset that his supposedly romantic gesture was just a sleazy attempt at manipulating her.]]
* SuckECheeses: Hoo-Has pizza place, complete with an animatronic rock and roll badger. Stan calls the place a nightmare, but is instantly seduced by the amount of money it can pull in.
* SuddenDownerEnding: [[spoiler:Dreamscaperers.]]
* SunglassesAtNight: Sheriff Blubs wears sunglasses while on a nighttime raid in "Headhunters".
* SurvivalMantra: Mrs. Gleeful has one. "Just keep vacuumin', ''just keep vacuumin'...''"
* SuspiciouslySpecificDenial:
** From "Fight Fighters":
-->'''Grunkle Stan''': There's a great uncles day?
-->'''Mabel''': Of course it's not a day I made up!
** From "The Deep End":
-->'''Mabel''': There's certainly not a ''mermaid'' in there if that's what you're implying. Who said anything about a mermaid?
** From "The Land Before Swine":
-->'''Grunkle Stan''': I'm not acting suspicious! You're acting suspicious! ''What's a pig?!''
* TakeThat:
** Grenda and Candy wanting to read [[ShoutOut "Wolfman Bare]] [[Literature/{{Twilight}} Chest"]] on their sleepover, and Dipper ([[FreakyFridayFlip in Mabel's body]]), is disgusted.
** The entirety of "Boyz Crazy" is a TakeThat towards 90's boy bands.
*** More specifically, it was a TakeThat against the highly manufactured nature of 90's boy bands, and less against the actual singers themselves.
** One of the chants in "Dreamscaperers" is "Inceptus Nolanus Overratus," which roughly translates to "''Film/{{Inception}}'' [by] Nolan [is] Overrated."
** In "Soos and the New Girl", there's a store in the mall clearly modeled after Hot Topic called "Edgy on Purpose".
** The "Clay Day" short from "Little Gift Shop of Horrors" makes a jab at CGI animation for killing off StopMotion animation, but also at people who claim that CGI is inferior to StopMotion because it "has no heart".
** Similar to "Boyz Crazy", the entirety of "The Love God" is a big joke against the hipster community, something which Oregon is infamous for.
** At the start of "Northwest Mansion Noir/Mystery", Dipper is watching a show called [[Series/GhostHunters Ghost Harassers]] on the Used To Be About History Channel. Other programs include Crawdads in Tiaras and Florida: The Show.
* TakingAdvantageOfGenerosity: Wendy very much takes advantage of Mabel's BenevolentBoss attitude in "Boss Mabel."
* TagAlongKid: Inverted by Soos, who often fills this role. He's an adult but enough of a man child to be more like a knuckleheaded tag along big brother.
* TaxidermyTerror: [[spoiler: The Lumberjack's Ghost in Northwest Mansion Mystery animates all the taxidermy in the house, making them bleed from the mouth, chant about "ancient sins", and attack the guests at the party.]]
* TheOnlyOneITrust: While Dipper has yet to truly be betrayed by anybody, the journal he finds warns him not to trust anyone in Gravity Falls. Dipper decides that there is one person he can always trust: Mabel.
** In "Not What He Seems", [[spoiler: she ends up betraying that trust by letting the portal beneath the Shack activate, choosing to place her faith in Stan's convictions over Dipper's caution]].
* TheTalk: Stan decides to give one to Dipper in the episode "Carpet Diem". Unfortunately, it's Mabel in Dipper's body. [[FreezeFrameBonus Blink and you'll miss it]], but the title of the book Stan uses is ''Why Am I So Sweaty: Your Body Explained in Horrifyingly Uncomfortable Detail''.
-->'''Mabel:''' Goodbye childhood...
* ThereWasADoor: When Mabel drives away with Mermando in "The Deep End", she breaks an entirely new hole in the chain-link fence instead of going back out through the one right in front of her. This could be attributed to RuleOfCool or RuleOfFunny, though.
* TeamPet: Waddles the pig.
* TeamRocketWins: [[spoiler: See TheBadGuyWins above.]]
* TearsOfJoy: The Summerween Trickster cries tears of candy corn [[spoiler:[[ItMakesSenseInContext when Soos eats him]].]]
* TheTeaser: Each episode begins with a cold open.
* TechnologicallyBlindElders: Dipper and Stan [[ItMakesSenseInContext think that Robbie is brainwashing Wendy with his music]], so they take his CD and try to listen to it slowed down. Stan mistakes it for a vinyl record, and puts it into a record player. [[CaptainObvious It doesn't work]], and Stan is confused.
** In the episode "Little Dipper", Gideon [[spoiler:kidnaps Dipper and Mabel]], and he calls Stan for ransom. Stan doesn't believe him.
--->'''Gideon:''' "You don't believe me? I will text you a photo!
--->'''Stan:''' "'Text me a photo'? Now you're not even speaking English. (hangs up)"
* TeensAreMonsters: According to [[spoiler: the late owners of the convenience store]].
* TellHimImNotSpeakingToHim: Mabel gives Stan the silent treatment in "The Land Before Swine".
* TemptingFate: In "The Time Traveler's Pig", Soos comments that the only thing that could possibly cause the rigged dunk tank to dunk Stan is a "futuristic laser arm-cannon."
** Also, in "Headhunters", Mabel says she is "99% sure" she got rid of all the [[spoiler: wax statues]].
* TestosteronePoisoning:
** The manotaurs are testosterone ''waterboarding''.
--->'''Testostoroar:''' I have three Y chromosomes, six Adam's Apples, pecs on my abs, and fists for nipples!
** His name is "Manly" Dan for a reason.
* ThereIsAnother: [[spoiler:Gideon]] has the second volume of Dipper's book. And presumably there's a first... [[spoiler: Stan has it]]
* ThisIsMyChair: Stan and Gideon battle over a poolside chair in "The Deep End".
* ThoseTwoGuys: Lee and Nate in all their major appearances.
** Sheriff Blubs and Deputy Durland, as well.
* TickleTorture: In the episode "Little Dipper", Mabel and Dipper defeat L'il Gideon by tickling him until he loses control, at which point Stan rolls him out of the shop.
* TimeTravelEpisode: "The Time Traveler's Pig".
** And its sequel, "Blendin's Game".
* TimeTravelRomance: Briefly, but upon travelling ten years into the past, Dipper ends up running into a five-year-old Wendy. [[PrecociousCrush She thinks he's cute]], which gives him [[{{Irony}} a taste of his own medicine]].
* TomboyAndGirlyGirl: Wendy and Mabel respectively.
* TomeOfEldritchLore: Robbie uses a cursed CD case to hypnotize Wendy in "Boyz Crazy". You might even say it was a [[IncrediblyLamePun Necromisong]].
* TongueTrauma: Dipper came close to this in "The Hand That Rocks The Mabel".
** And then in "Carpet Diem", an owl apparently tried to eat Dipper's tongue while he was sleeping outside.
* TookALevelInBadass: Dipper and Mabel in "Headhunters"; Dipper deserves an honorary mention in "Dipper Vs. Manliness".
** Stan in "The Land Before Swine", when he attacks and rides a pterodactyl.
** Wendy in "Into The Bunker", no doubt.
** Soos in "Soos and the Real Girl".
* TooKinkyToTorture: Bill Cipher is a non-corporial being, so he can't experience physical sensations. That is, [[spoiler:until he tricks Dipper into letting him [[DemonicPossession possess his body]].]] He describes pain as "hilarious" and goes out of his way to abuse his new body as much as possible.
* TooMuchInformation: In the "Trooth Ache" section of "Bottomless Pit", Stan ends up wearing a set of false teeth that make him incapable of lying, and, apparently, discretion.
* TorsoWithAView: Happens to Dipper in "Dreamscaperers," though [[JustifiedTrope justified]] because he, Mabel, and Soos were [[ItMakesSenseInContext inside Grunkle Stan's head trying to stop a mind-invading demon from stealing the combination to Stan's safe.]]
** Also happens to [[spoiler: Dipper 2]] in "Double Dipper" after he [[spoiler: drinks some soda]]. Again [[JustifiedTrope justified]], because it's fairly obvious that [[spoiler: the clones don't have normal human anatomy internally, since they die when they're touched by water, and since Paper Jam Dipper was somehow able to live while looking like a slinky]].
* TotallyRadical: The members of Sev'ral Timez talk this way, as well as the boys from "Dream Boy High".
* ToughLove: [[spoiler:This is Grunkle Stan's mindset with how he treats Dipper]].
* TownWithADarkSecret: Almost said word for word by Dipper in "Tourist Trapped".
* TrademarkFavoriteFood: The recurring extra in the "Free Pizza" shirt really likes... pizza.
* TrainingMontage: Both Dipper and Grunkle Stan go through one in "Dipper vs. Manliness".
* {{Transflormation}}: All the party guests in ''Northwest Mansion Noir/Mystery'' get turned into tree-statues.
* TroublingUnchildlikeBehavior: Gideon's hobbies include [[spoiler: attempted murder]] and [[spoiler: demon summoning]].
* TruncatedThemeTune: Starting with ''Northwest Mansion Noir/Mystery'', a shorter cut of the intro is used.
* TruthInTelevision: From the landscape to the flora and fauna, rural Oregon is [[ShownTheirWork extremely well-represented in the show]]. Even the layout and occupants of the town, while exaggerated a bit, would fit right into that environment.
** In "Little Dipper", Dipper feels insecure because Mabel is revealed to be growing faster than he is, despite them being the same age. This makes sense: as anybody with a similarly-aged sibling of the opposite sex can attest, there is an awkward phase growing up caused by the fact that girls hit puberty earlier than boys.
** In "Northwest Mansion Mystery", the lumberjack ghost explains that he died because [[spoiler:the loss of too many trees ended up causing a landslide.]] In RealLife, tree roots play a very important role in soil stability, and deforestation poses a high risk for landslides.
* TwentyMinutesIntoThePast: The show is set in the summer of 2012, exactly when the series debuted. Later seasons become this trope though it seems to be intentional, given the supposed 2012 apocalypse.
* TwoGirlsToATeam: The Mystery Shack is made up of three guys and two girls.
** Not counting the twins, Wendy's gang of friends is made up of four guys and two girls, [[spoiler:at least until Robbie broke up with her]]. Justified since Wendy is OneOfTheBoys.
* [[invoked]]UnfortunateImplications:
-->'''Soos' Grandmother''': I would like to see you settled before I ascend to heaven to live with the angels.
-->'''Soos''': And with Grandpa!
-->'''Soos' Grandmother:''' ...No...he is not there.
* UltimateEvil: Bill Cipher, the most powerful monster ever encountered by the writer of the books.
* UnexplainedRecovery: Agent Powers and Agent Trigger surviving the zombies that dragged them into the woods in "Scary-Oke". Subverted in "Not What He Seems", when Powers explains he used Trigger as a human shield.
** Again in "Not What He Seems", Trigger's escape from the crashed Humvee with his ear-microphone destroyed and a tree branch restraining him was off-screen.
* TheUnHug: Awkward sibling hug.[[note]]Pat. Pat.[[/note]]
* UnlimitedWardrobe: Mabel wears a different sweater in every episode, sometimes even multiple sweaters in the same episode.
** [[JustifiedTrope Justified]] in that Mabel makes her own sweaters - you will see her periodically working on new sweaters throughout the series.
* UnPerson: [[spoiler: Quentin Trembly.]]
** This is how [[spoiler:Bill Cipher]] describes Dipper once he has [[spoiler:[[GrandTheftMe taken over his body]]]].
* TheUnreveal: Soos finds a memory in which Stan enters the secret passage behind the snack machine, but closes the door before he can reveal what’s behind it, proclaiming it "boring."
** In one of the "Dipper's Guide to the Unexplained" shorts, Dipper and Soos find an all-knowing mailbox entity. After testing it with a few questions, they are just about to ask "Who wrote the journals?" Sadly, Mabel comes in and puts in a video of her shoving gummy worms up her nose, and the mailbox, offended, vanishes explosively.
* UnscientificScience: In "Carpet Diem", Dipper explains how [[spoiler:Experiment 78 switches minds]]:
--> '''Dipper''': ''(reads the label)'' "[[spoiler:Electron Carpet]]. Atoms can switch electrons. The [[spoiler:carpet]] must create a charge so strong that ''[[spoiler:it can switch MINDS]]''!
* VacuumMouth: The skull from the ''Tumbleweed Terror'' pinball game.
* VagueAge: Gideon Gleeful. His white hair suggests he's OlderThanHeLooks, but he's extremely short and has a baby face. His age has yet to be revealed in the show, but [[AllThereInTheManual supplementary material has confirmed that he's nine.]]
** Soos was this until the episode "Blendin's Game", where it's finally confirmed that he's 22.
* VaguenessIsComing: Bill Cipher gives on of these to Soos and the twins near the end of "Dreamscaperers", telling them that "a day will come in the future where [[NothingIsTheSameAnymore everything [they] care about will change]]".
** They get the same treatment three episodes later, this time by [[spoiler:Experiment 210.]]
* VampiresAreSexGods: The G-Rated version. Brought up by Mabel several times.
* VanityLicensePlate: If you look closely, the plate on Grunkle Stan's car says "STNLY MBL".
** [[spoiler:Which is strange when you realize that Stan's name is Stan''ford'', not Stan''ley''.]]
* VerbalBackspace: This happens multiple times in ''The Legend of the Gobblewonker'' when Dipper needs to reasses the number of back-up cameras he has when they get smashed.
* VignetteEpisode:
** "Bottomless Pit"; the gang tells stories to pass the time while they're trapped in the titular pit.
** "Little Shop of Horrors"; Stan tries to convince a stranger who arrives at the Mystery Shack after hours to buy stuff by telling tales about them.
* VillainWithGoodPublicity: Everyone considers Gideon to be a cute lovable child. [[spoiler: That is, until the Season 1 finale when Stan exposes the truth about Gideon, and ends Gideon up in prison.]]
** Turns out the [[spoiler:Northwest family is this as well]].
* VillainousCrush: Gideon has one toward Mabel.
* VisualPun: The Mystery Shack's sign has the second S in an odd position or completely taken off, spelling out MYSTERY HACK. Considering who owns the place...
** Additionally, Candy dressing like a piece of candy in "Summerween".
* VocalEvolution: It took Alex Hirsch a few episodes to settle into his Grunkle Stan and Soos voices. They sound a little off and unusually high-pitched in the beginning.
* VoicesAreMental: In "Carpet Diem", the voices switch along with the characters as they move from body to body, and [[spoiler: Bipper has Bill Cipher's voice coming out of Dipper's mouth]]. In both cases, this is just for audience convenience. None of the other characters seem to notice.
* VoluntaryShapeshifting: Experiment 210, an EldritchAbomination that the gang encounters while seeking out the Author.
* VomitDiscretionShot: While the gnome vomits on screen, it throws up rainbows. Taken to extremes when it fills up the entire closing credits of the first episode.
** Later, in "Boss Mabel", we see a group of tourists from Stan's point of view. They all appear as walking, talking wallets, and one of them vomits ''coins''.
** In "Carpet Diem", Mabel, in Dipper's body, pukes into a toilet.
* WeirdnessCensor: This is probably one of many reasons that the residents of Gravity Falls still live there; they never believe when they actually see something supernatural, and when they do, they ignore it like it was nothing.
** [[spoiler: "Society of the Blind Eye" revels that the [[AncientConspiracy titular Society]] has been acting as one, erasing the memories of people who have seen anything supernatual.]]
** Even after the events above, the citizens still try to rationalize the weirdness. For instance, the [[spoiler: gravity anomaly]] is passed off as a mini Earth burp.
* WeirdnessMagnet: It's true that Dipper often goes off looking for the supernatural, but more often than not, the supernatural finds him first.
* WeWillMeetAgain: Used three times so far: the leader of the gnomes, Gideon and Blendin Blandin all swear revenge after being defeated.
* WhamEpisode:
** "Dreamscaperers" has [[spoiler:Gideon, after the Pines foil two attempts at getting the deed for the Mystery Shack from Stan's safe, instead blows up the safe with dynamite and immediately brings in a demolition vehicle to start tearing down the Shack while the Pines and Soos look on in horror.]]
** In "Gideon Rises," [[spoiler: Stan reveals to the townspeople that Gideon was illegally spying on them. Gideon is sent to jail, leaving behind the second journal. Dipper and Mabel decide to tell Stan about the journals... unwittingly giving him ''all three journals.'' Because not only did Stan take Gideon's book, he's had the first one all along. The episode ends with Stan ready to open... something.]]
** "Society of the Blind Eye" [[spoiler:not only completely overturns a popular and supposedly supported fan theory, but ends with some dark (and ''bloody'') potential foreshadowing.]]
** "Northwest Mansion Noir/Mystery": [[spoiler: The Northwest family as it turns out has been one long chain of cheats, Pacifica has been a victim of abuse and ends her rivalry with the Pines twins, and according to [=McGucket=], the ''apocalypse is coming'' in less than a day]].
** "Not What He Seems": [[spoiler: Stan's been stealing radioactive waste to power his world ending machine and gets arrested by the FBI. The twins discover that the real Stan Pines died in a car crash and that their grunkle is [[TitleDrop not what he seems,]] all leading up to a confrontation as gravity fluctuates when the portal rips open, revealing the author of the journals, Stan's brother.]]
* WhamLine:
** "After all these years... Finally, [[spoiler:I have them all.]] [[CliffHanger Here we go]]."
** "The author of the journals... [[spoiler: my brother."]]
* WhamShot:
** At the end of "Northwest Mansion Noir/Mystery", [[spoiler: [=McGucket=] has fixed the laptop. There's a timer on it counting down to the apocalypse. ''It's less than 24 hours away.'' And then the camera pans to a banner the Northwests have in their house of a familiar triangle with an eye, over an image of what looks like people ''burning alive.'']]
** In ''Not What He Seems'', [[spoiler: Stan's portal finally opens and a man steps out, who he identifies as the author of the journals, his brother.]]
** And before that, a newspaper clipping that reads [[spoiler:''Stan Pines Dead'']], though what this means for the characters is still unknown...
* WhatDidIDoLastNight: Mabel after waking up from her sleepover with Candy and Grenda.
* WhatHappenedToTheMouse: So far, the two Dipper clones that rode away on Robbie's bike in "Double Dipper" have yet to return.
** As has the [[ItMakesSenseInContext wax head of Larry King]] from "Headhunters".
** A minor example: in the fourth episode, Mabel saves a lobster that was going to be eaten at a restaurant then bring it to the shack's tank. In later episodes, the tank is empty.
* WhatHaveIBecome: In "Boss Mabel", Mabel reaches her breaking point with Soos and Wendy. She tells them off for their goofing off in a Stan-like manner, ending up with the fez on her head. She quotes this verbatim when she looks in the mirror.
** Though considering all that happened, she had a reason. Dipper himself stated: [[IDidWhatIHadToDo "What you had to, Mabel."]]
* WhenLifeGivesYouLemons: Each member of the Pines family has a character-establishing quote based on this:
--->'''Dipper:''' "When life gives you lemons, extract the juice and use it to draw a treasure map in invisible ink. That really works! Seriously!"
--->'''Mabel:''' "When life gives you lemons, draw faces on those lemons and wrap them in a blanket. Ta-daaa! Now you have Lemon Babies."
--->'''Grunkle Stan:''' "When life gives you lemons, call them 'yellow oranges' and sell them for double the price."
* WhatMeasureIsANonHuman: Played for laughs in "Summerween". Soos hits the Trickster and shatters him completely when he was about to kill the kids, and freaks out when he thought he accidentally hit a guy. [[spoiler:After Soos eats the Trickster, the episode draws to a close with an {{Everybody| Laughs Ending}} {{Evil Laugh}}s [[EverybodyLaughsEnding Ending]] as soon as it ends, Soos nonchalantly says "I ate a man alive tonight."]]
** It should be noted that [[spoiler:The Trickster was very happy that Soos liked eating him.]]
* WhenYouComingHomeDad: [[spoiler:Soos]] is really hung up about his deadbeat dad.
* WhereTheHellIsSpringfield: In Tourist Trapped, the map of Oregon shows Gravity Falls to be dead-center in Oregon, somewhere between Crook and Deshutes county. But in Skaryoke, a doppler map places it closer to Baker city, almost on the border with Idaho.
* WhichMe: In "Double Dipper" a few times.
-->'''Tyrone:''' Hey buddy, it's me, you.
* WholeEpisodeFlashback: "Bottomless Pit!" is focused on the characters telling stories, at least one of which we discover actually happened. Also qualifies as a VignetteEpisode, as listed above.
* WhoNamesTheirKidDude: It's revealed in "Double Dipper" that Dipper is OnlyKnownByTheirNickname, causing Wendy to remark "I thought your parents just hated you or something".
* WidgetSeries: Definitely the most off-kilter series on the channel.
* WildGooseChase: In "Not What He Seems", Stan pays a taxi driver to drive in the opposite direction he's running in order to misdirect the government agents trying to arrest him.
* TheWildWest: The theme of the ''Tumbleweed Terror'' pinball game.
* WildWilderness
* WimpFight: In "The Hand that Rocks the Mabel", [[spoiler:Dipper and Gideon]] manage to get into one while ''falling off a cliff'', a stark contrast to [[CurbStompBattle the one that they have]] [[spoiler:during the season finale]].
** In "Double Dipper", this ends up happening between Dipper and all his clones. Dipper even [[LampshadeHanging lampshades]] this beforehand, saying "We're all exactly the same mentally and physically. If we start fighting, it'll just go on for infinity!"
* AWizardDidIt: A number of plot holes are filled by the reminder that Quentin Trembley passed a ''lot'' of weird laws in his time in Gravity Falls office. It's why holding the physical deed to a building - holding it in your hand - means you own the building, and why the police are allowed to [[spoiler: send a nine-year-old to adult prison.]]
* WoobieDestroyerOfWorlds:
** Giffany counts for some, given that she has abandonment issues and that no one in her debut episode treats her like a person: Soos breaks up with her because she can't attend his cousin's engagement party, Mabel and Dipper encourage Soos to date real girls and return Romance Academy to the store, and three other people have apparently returned her without even a MercyKill. That said, she is more "destroyer" than "woobie" in that she takes over Hoo Ha's Jamboree to stalk Soos, force him to upload his brain into the game, and [[BreakThemByTalking break him by talking]].
** The lumberjack ghost in "Northwest Mansion Noir" has no qualms about [[WouldHurtAChild hurting children]] in his quest for revenge on the Northwests, but he and the other lumberjacks who died were cheated out of a party supposedly held in their honor, and he suffered a CruelAndUnusualDeath. Dipper even expresses some SympathyForTheDevil while exorcising the ghost to keep Mabel safe.
* TheWorldIsNotReady: Based on the events of "Boss Mabel", it seems that the tourists aren't quite up to seeing real magical creatures just yet.
* WorstNewsJudgementEver: "Cheese Crust Pizza Declared 'Delicious'." In other news, "War or Something..."
* WouldHurtAChild:
** [[spoiler:The cursed wax figures]] in Episode 3. They try to murder Dipper and Mabel without hesitation.
** Also, in "Summerween", [[spoiler:the Summerween Trickster. In fact, he makes it look like he KILLED a child until the end of the episode!]]
** Rumble, the Fight Fighter, was genuinely trying to kill Robbie, endangered Stan and Mabel by toppling the water tower, and beat up Dipper with a nearly lethal combo attack just because Dipper had lied to him.
** Every antagonistic creature/person in the series ''ever'' qualifies as this.
* WorldOfBadass: ''Every'' major character is some form of badass, be it often or [[LetsGetDangerous only when the situation calls for it]].
* WouldntHurtAChild: [[spoiler:The convenience store ghosts]] in Episode 5. They ''would'' hurt teenagers though.
** Robbie in "Fight Fighters". Even after Dipper nearly gets him killed, he's unwilling to go through with beating him up.
* WrongGenreSavvy: Mabel in "Sock Opera" towards the end:
-->'''Mabel''': Don't worry, I have seen enough movies to know this is the part where the audience thinks this was all part of the show and loves it. Cue applause!
-->''(audience boos and leaves)''
* XMeetsY:
** ''Series/TheXFiles'' meets ''Series/{{Goosebumps}}'' meets ''Literature/TheSpiderwickChronicles'' with a bit of ''WesternAnimation/RegularShow''-style weirdness (and slightly similar art style).
** ''EerieIndiana'' as directed by DavidLynch.
** The show is set in Oregon, just like in ''Series/{{Grimm}}''.
** Could also be described as very much like ''RoundTheTwist'' in cartoon form, set in the USA.
** Could be ''Podcast/WelcomeToNightvale'' 's TV kid cousin.
** Alex Hirsch himself described the show as ''Series/TwinPeaks'' meets ''Series/TheSimpsons''.
* XtremeKoolLetterz: Sev'ral Timez.
* {{Yandere}}: Gideon.
** Newly, and on a higher level, [[spoiler:Giffany]].
-->[[spoiler: '''Giffany''']]: Oh, I am crazy! Crazy for you, [[spoiler: Soos]]!"
* YellowEyesOfSneakiness: Bill Cipher has a slitted pupil, and his sclera turn yellow when he [[spoiler:possesses a body]].
* YouAreNumberSix: How Dipper names his clones, with the exception of Tyrone (who refuses to be called "Number Two") and Paper Jam Dipper.
* YouCantFightFate: In "The Time Traveler's Pig," no matter what he tried, Dipper would always inevitably hit Wendy in the face with a baseball. The one time he ''finally'' figured out how to avert this [[spoiler:he needed Mabel to help so she wasn't there to win Waddles and Pacifica got him instead. For Mabel's sake Dipper had to go back and hit Wendy again.]]
* YouExclamation:
** In "Double Dipper", after melting his photocopied clones to mush, Dipper believes they're all gone. Until he hears Tyrone exclaim "YOU!" from behind.
** In "Boss Mabel", Mabel gives one of these to Grunkle Stan when she gets tired of the shabby treatment he gives his employees and his customers.
** In "The Land Before Swine", Grunkle Stan gives one to Mabel's pet pig Waddles after the latter eats the former's corn-cob sculpture of a unicorn, driving away Stan's customers.
** Bill Cipher tosses out a few in "Dreamscaperers."
** Rumble [=McSkirmish=] gives Dipper a ''really'' [[ChewingTheScenery over-dramatic]] one in "Fight Fighters".
* YouGottaHaveBlueHair: Kraz.
* YouKilledMyFather: Dr. Karate killed Rumble [=McSkirmish's=] father (again), making it his motivation for fighting. Rumble also assumes that this is the reason Dipper wants him to fight Robbie.
* YouFailPaleontologyForever: "Land Before Swine". Not only is the "pterodactyl" completely ugly (see PteroSoarer) for details, but all the dinosaurs are hard to look at. Plus Oregon is actually one of the few states that has had no dinosaurs discovered in it.
** Note, however, that just because no fossils have been found yet doesn't necessarily mean dinosaurs didn't live there. The rest of the episode's problems still qualify though.
* YouMeanXmas: Apparently, the citizens of Gravity Falls love Halloween so much they celebrate it twice and call the second time "Summerween". It's exactly the same except they carve watermelons instead of pumpkins.
* YourWorstNightmare: You get to see it if you look into a Gremloblin's eyes.
** In "Dreamscaperers," [[spoiler:Bill unleashes Mabel and Soos's personal nightmares on them after they stop him from getting the safe code]].
* YourMom:
-->'''Nate:''' Good job throwing the kid off the fence, genius!
-->'''Lee:''' Your mom's a genius.
* YouthIsWastedOnTheDumb: In "The Inconveniencing", the twins tag along with Wendy and a bunch of her friends while they break into an abandoned convenience store, and they aren't able to do a darn thing once [[spoiler:it turns out to be haunted]].
* ZombieApocalypse: Nearly happens in "Scaryoke", when Dipper [[EpicFail accidentally raises an army of the undead]] while [[spoiler:trying to prove the validity of the journal to the government agents]].
* ZombieGait: Referenced when Wendy and Dipper watch a cheap zombie movie:
-->'''Dipper:''' They're slow! Just power walk away from them!
