Open Mouth, Insert Foot

Go To

"Right. Right. 'Cause there's a lot stupider names than Chi Chi. I'm not saying that Chi Chi's a stupid name. I'm just saying that it's not normal. Ah. But normal is overrated. I'm not saying that you're stupid or overrated. I'm just— I'm gonna stop now."

A character with a big mouth says something stupid or, better yet, self-incriminating, often with the subject of their commentary standing nearby or, better yet, right behind them.

The trope name comes from the phrase "to put your foot in your mouth" (also playfully referred to as "foot-in-mouth disease", a pun on the very serious livestock illness "foot-and-mouth disease").note 

A subtrope of Fee Fi Faux Pas and closely related to Ignore the Disability.

Compare Shutting Up Now for a similar reaction. Can lead to any of the following: Change the Uncomfortable Subject, Digging Yourself Deeper, Did I Just Say That Out Loud?, That Came Out Wrong. Sometimes more than one.

Don't confuse for "Open mouth, insert food", as if this is about eating.

    Anime & Manga 
  • Deconstructed in Asteroid in Love. Ao developed a fear of speaking because she was teased for one of these during the sixth grade when she accidentally made an innuendo:
    Ao: So hot...anybody feel it's super wet today?
    Classmate A: I think "humid" is the word you're looking for?
    Classmate B: (Yelling to the rest of the classroom) Hey guys! Ao just said something really dirty!
    Other Classmates: Ao is dirty!
    (Ao gets Quivering Eyes)
    Present-Day Ao: Since then, I've had trouble speaking up.
    Suzu: That changed her whole personality?!
  • Cowboy Bebop: Spike is very aware of this trope.
    Open foot, insert mouth.
  • The title character of Crayon Shin-chan can be really naive and straightforward at times. Notably, an episode where Ume Matsazuka has to be separated from her boyfriend Tokuro due to the latter having a job posting to South Africa; Shin-Chan and friends tries cheering up Ume, but Shin-Chan who's first to talk immediately tells her about a neighbor of his celebrating her wedding and going on her honeymoon a week ago (cue Collective Death Glare from everyone).
  • Done in epic fashion in Death Note when L asks Light how, as a detective, he would go about trapping Kira, Light's secret Serial Killer alter-ego. Once Light has given L his answer, L "praises" him by pointing out that while it usually takes professional investigators several minutes to even come up with an answer to that question, Light immediately responded with an answer that a serial killer talking directly to the investigators would give.
  • In Digimon Adventure's English dub, Joe Kido does this twice when the kids are going to go back to the real world from the digital world without their digimon. He even says the trope name the first time around.
  • Latvia of Hetalia: Axis Powers is prone to this, which is a very bad thing when Russia is constantly hanging over your shoulder. Often closely followed by Lithuania or Estonia's "Latviaaaaaaaaaaa!"
    Latvia: I do feel safer in his hairy arms.
    Estonia: You should really keep your mouth more closed.
  • Tsurubami Kamome from Medaka Box actually gets kicked in the mouth twice for doing this too often. Not that it hurts him.
  • Rebuild World: When Sheryl mentions she only ordered coffee because she's on a diet (which is a lie to cover up that she's poor), Katsuya says Sheryl has Curves in All the Right Places, basically calling her fat, which his female companions call him out on.
  • In She's My Knight, Ichinose, despite being popular and attractive, has no tact at all.
    Ichinose (trying to ask Mogami to a movie): I bet you have too much time on your hands after school. I can take you to a movie, 'cause I feel bad for you.
  • In Wasteful Days of High School Girls, most of Majime's interactions with Robo come off as this, as she gets so nervous that whatever she blurts out doesn't make a lick of sense.

  • Archie Comics (2015): Archie agrees to come camping with Jughead, but almost immediately gets distracted and takes them towards a girls' camp instead. When Jughead complains, Archie responds "I won't apologise for being a normal guy!" Jughead, being asexual in this continuity, is stunned speechless. Archie immediately realizes how that came out and apologises, but Jughead is uncharacteristically thrown and seems genuinely hurt.
  • Forgotten Realms:
    • In one issue, a bronze dragon mistakes the wizard Dwalimar Omen for the famed Elminster, Sage of Shadowdale. Omen scoffs at this, calling Elminster "overrated" and dismissing him as a "feeble-minded hedge wizard" who couldn't hold a candle to even the lowliest mage from Omen's native Halruaa. Elminster himself arrives soon afterward, and having clearly overheard Omen, he sarcastically introduces himself as "Elminster the Overrated". The closing textbox of the issue lampshades the trope:
      Join us next month to watch Omen try to remove his foot from his mouth!
    • In the second issue, the elf cleric Vartan Hai Sylvar brings up the wizard Ostus Agrivar while remarking on Priam Agrivar's family name. He mentions that he heard Ostus got eaten by a demon and effectively says that it served him right for dabbling in matters beyond his feeble human ken, only to become contrite and apologize after Priam reveals that Ostus was his father, who was murdered in front of Priam by the demonic sorcerer Imgig Zu.
  • Powers Vol 2 #13 has Detective Pilgrim exclaim, upon hearing that a homicide that left a street of collateral damage has only one witness, that she had more witnesses when she lost her virginity.
    "That's one of those things I wish I hadn't said out loud."
  • Spider-Man, in any continuity, has a very bad habit of doing this, since his defense mechanism against people tougher and/or deadlier than him is his wit. At the very least, it's a Death Glare. At the very most, he'll start running.

  • #8024: When Batman sends Nightwing and Red Robin to visit Marinette at Arkham Asylum and ask her a few questions about how she ended up there, she takes one look at their costumes and asks "Is this an interrogation or a plea for help because your team's outfits are terrible?" She's immediately horrified, though both take it in stride:
    Nightwing: ...Well then. That's, uh, the that's the first time one of these was started by criticism on our outfits—
    Red Robin: Speak for yourself. (chuckles) You sure? I enjoyed the comments on Hood's helmet, definitely — but what about you? When you went around as Discowing? I'm half-tempted to give her a photo of you like that just to see her reaction.
  • All Assorted Animorphs AUs: In "What if Rachel's mom was a controller?", Rachel tells Tobias that she doesn't want to fight because some of them have families who depend on them, then regrets it when she sees the stricken look on his face.
  • While discussing Su's desire to up the security at the Hinata Inn in The Beast That I Am (to stop the Ogre if she shows up again), Keitaro tries to dissuade Kitsune by pointing out that eventually Su will turn all of that security on him.
    Kitsune: But it ain't a big deal when bad stuff happens to you! It's me and the other girls I'm worried about!
    Keitaro: Wait... what did you just say Kitsune?
    Kitsune: I said it's me and the other girls I'm worried about! It don't matter when bad stuff happens to -! Well, what I mean was that... well, you're indestructible. You and I both know that!
    Keitaro: Uh... yeah.
  • Child of the Storm has it Played for Drama in the sequel when Maddie, whose social skills are somewhat lacking, picks a very unfortunate moment to tell Jean that her boyfriend is cheating on her (having just found out via her own Telepathy). Specifically, when said boyfriend was meeting her parents. Jean, unsurprisingly, blows up, having been under a lot of pressure to begin with, and ends up taking it out on Maddie, who is miserable because she didn't want to hurt Jean and was only trying to help.
    • It's also played seriously earlier on in the sequel in the case of Harry's friends after he returns to Hogwarts — having been through an epic Trauma Conga Line, he really does not have the patience for teenage idiocy anymore. Thankfully, some counseling and the passage of time helps him cool off a bit.
  • In Chrysalis Visits The Hague, The protagonist Estermann says the following to Lyra, a pony (It Makes Sense in Context):
    Estermann: Because as far as I'm concerned, a pony's only good to be ridden and sliced up for sausage. How the hell am I supposed to make myself a picture of one's 'inner workings'?
  • Played for Drama in the The Loud House fanfic A Dark House: Inadequate when Lori, in a fit of anger over some broken perfume, snaps at Lincoln that sometimes she wishes she didn't have a brother. While she quickly realizes what she said and is clearly upset, Lincoln runs off in tears and locks himself in his room, even shouting that no one cares about him when Lori and some of the other girls try to talk to him.
  • Elecktrum's Narnia Fics are full of this trope. One fic revolves around it completely, and another has a chapter revolving around the similar phrase "eating crow." Her OCs and minor characters also get into the act, especially where Edmund is concerned:
    • Tumnus unintentionally insults Edmund by implying that Edmund had worked for the white witch in "The Conscience of the King".
    • In "Black Dwarfs, Blue River" an overzealous faun angrily tells Edmund regarding the persecution of families of some satyrs who fought on the witch's side that the wives and children (who did not fight for the witch) were "Sons of traitors [who] deserve what what they get." Edmund responds coolly: "so what will you call my sons?" Oops.
    • And then there's Ilano's Right in Front of Me moment in "They Also Serve".
  • Eleutherophobia:
    • In These Are the Damned, Jake said in an interview that when he was a kid, he wanted to grow up to be like Kevin Johnson... or his own older brother. Eight hours later, Tom is still getting phone calls asking for a quote.
    • In THX 1138, Colette wonders out loud why Tom's parents weren't suspicious when he started getting straight As after becoming a Controller... and immediately regrets it when Tom freezes.
    • When Rachel chastises the Animorphs for drifting apart in How I Live Now, she starts to mention how Marco let Jake sleep over at his place when Jake didn't want to deal with "Tom", but interrupts herself when she remembers that Tom is present.
  • Enchanting Heist:
    • Ryuji as always, has a tendency to spout out thoughts that he soon comes to regret even if he means well. A notable example occurs when Ryuji finds out that Luz has a girlfriend, wherein he accidentally blurts out his surprise that she is attracted to other girls due to having never met someone attracted to the same sex before. when Luz gets upset and starts to storm off, Ryuji quickly apologizes, and states that he doesn't judge her.
    • Luz herself is guilty of this as well. When she is whisked off to the Velvet Room for the first time, Luz accidentally lets slip that she actually has prior knowledge of Personas from other sources, due to Eda, and Philemon teaching her about them before she ever made contact with the Velvet Room. To say that this is a massive shock to the Velvet Room inhabitants is an understatement, as Caroline and Justine both perform a Jaw Drop and even Igor is visibly surprised. Luz nervously lampshades that she probably shouldn't know about what her new powers are yet based upon their reaction.
  • Epiphany: After having an erotic dream about Sephiroth, Aerith finds him and accuses him of infiltrating her dreams only to quickly realize he has no idea what she's talking about, and her evasive answers about the nature of the dream only make him more intrigued.
  • In the Back to the Future fanfic Homecoming, George, not knowing about the age gap between Doc and Clara, asks where "Mrs. Brown" is. He's mortified when he finds out that Clara is Doc's wife, not his stepdaughter, and apologizes profusely.
  • Khaos Omega has one character often do this. Whenever Yolande Azeat says something that comes out wrong, her butthole usually ends up getting sexually destroyed (especially if Jet's nearby when it happens).
  • In Kira, Sweetheart Light has one of these moments when he discovers that L has been abused in the past.
    Light: WHO did this? Give me their name!
  • The Mountain and the Wolf: Played for Drama when Tyrion is discussing the unknown traitor (who opened the gate of King's Landing during the siege) with the Wolf, a Chaos Norscan the size of a bear. Tyrion realizes his comments imply that the Wolf is behind it, and he has a very uncomfortable moment when he sees the Wolf getting angry (especially since the viewer knows the Wolf is behind it). Fortunately, it turns out the Wolf was thinking up a plausible explanation that Tyrion believes to be the truth.
  • The My Little Pony: Friendship is Magic fanfic The Model Caretaker Has Fleur de Lis struggle with this in the first half of the story, especially when Fluttershy is about.
  • A Moon and World Apart: Rarity has a bad case of this in chapter 7, when she first starts flirting with (unbeknownst to her) a married stallion, then (after being informed of his marital status) wrongly assumes the mare with him is his wife. Then she gets really mortified at her actions when she finds out he's actually gay. To her credit, she does apologize to both he and Twilight for the misunderstanding and any offense she may have caused as soon as she can.
  • In My Huntsman Academia both Izuku and Nora are frequently guilty of this. The former's tendency comes from his social awkwardness, while the latter's comes from her Cloudcuckoolander tendencies. For instance, the following conversation Izuku has with Weiss:
    Izuku: (when Weiss asks what he isn't good at) W-W-Well, I'm not good with t-talking to people! I get really nervous, and I can't even talk to girls sometimes without just going blank.
    Weiss: (snorting) You're doing a fine job with me at the moment.
    Izuku: Yeah, but I don't see you as a girl. (Beat as Izuku goes sheet-white)
    Weiss: Explain. Now.
    Izuku: I-I-I-I didn't mean it l-l-l-ike that Weiss! I m-mean I just see you as a teammate! I know you're a girl! A smart, nice, pret-
    Weiss: Compliments later! Speak!
    Izuku: (curls up into a ball as she looms over him) B-But it's easier to just see my teammate! When I think about it, I get all n-nervous and shakey, so it's just simpler that way! Please don't be mad!
  • My Lesbian Life with Monster Girls: Monster Yurisume: In chapter 129, Yuisu, overworked and stressed out, chews out Haru for changing her mind about getting printer paper when Yuisu asked and forgetting to tell her, which leads to her declaring that Haru never takes her requests seriously, citing the fact that Haru dyed Hakuto pink after Yuisu literally begged her to stop the prank war as proof. All Haru can think of to say in response is, "That was different. I mean, I had already ordered the hair dye", which really sets Yuisu off.
    Yuisu: Oh, so that's how it is. My heartfelt plea is worth less than a bottle of hair dye.
  • In Neither a Bird nor a Plane, it's Deku!, Professor Stein gushes over the possibility of being a godfather when Hisashi is discussing his sudden vacation. He quickly apologies when Hisashi screams about how he's infertile. He does end up becoming a godfather when the Midoriyas adopt a baby Kal-El.
    Stein: Congratulations, Hisashi, my boy! You're going to be a great father, I just know it! Can I be the godfather? I've always wanted to be a godfather, Hisashi!
    Hisashi: Yeah, well that's not going to happen, because we can't have any kids! (spits a stream of fire out of frustration)
    Stein: Um, well, now that you've finished whatever that was and I've finished removing that foot from my mouth, allow me to apologize, again.
  • The New Look Series has several examples of this trope.
    • Young Link gets in trouble with Peach due to him pretending to be her, mockingly.
    • Kenshin also gets in trouble when he tells Kaoru that he can't understand what Kaoru is going through right now because he isn't a woman like her.

  • In Patterns of the Past, the Patternista taunts the rescue team by telling them that they have no way to contact anyone for backup. Orscheln, the sole Scientist on the team, then reveals that Dr. Ozzington, Precinct 13579's Lab Director and her boss, has a portable Telephone-inator handy, which elicits a couple gasps from the other agents on the team and leaves Olesya cold. This causes the Patternista to notice O'Sullivan reaching in his Hammerspace spine for a gadget, as she orders him to stop and threatens to kill Old Missie with her gun if any of the agents use gadgets against her.
  • In the prequel to Respawn of the Dead, Heavy accidentally insults Medic a few times. But, to be fair, it's pretty clear that Medic is only insulted by being told he sounds like Greta Garbo because he has no idea he was practically quoting her.
  • Revelation (Helluva Boss/Hazbin Hotel) plays this for drama. Two years prior to the story, Alastor managed to kill Lucifer and took over as ruler of Hell, turning it from a kingdom of hedonism and chaos to a totalitarian fascist regime. Anybody who criticizes him or his rule is considered a traitor and sent to the Pit Of Fire. The whole plot is kicked off when Moxxie, after being grilled by Katie Killjoy on a live interview, accidentally calls Alastor's elite army, the Crimson Guard, "brutal". This has disastrous consequences for not just him, but also for anybody who associates with him or have just been in his vicinity.
  • From another MLP fanfic, The Rise of Darth Vulcan: Artful Dodger is discussing showering with Eiderdown and starts speaking before thinking.
    You could literally see the words traveling from his mouth, to his own ears, and from thence to his brain. His eyes went round for a second. "Once. One. At a time, that is. Not that there isn't enough room for two. Heh. I mean—- I'll go first, that way you can take your time. Afterward. By yourself." He literally shoved his own hoof in his mouth to shut himself up. He bit down on his hoof for a second then spoke around it. "G-g-give you time to, uh, pretty yourself up afterward...."
  • In the Rivals Series Viktor can't help but unintentionally offend Yuuri through unwanted advice or very poor wording which doesn't help Viktor's attempts to get Yuuri to at least tolerate him. Then Viktor starts to develop the opposite problem so Yuuri would at least speak to him.
  • SAO: Mother's Reconciliation: In chapter 9, Kyouko ends up doing this when she tells Asuna that since her brother turned out successful because he listened to her and followed her orders, Asuna should just "stop wasting her time and theirs, and do what she says." This ends up pissing Asuna off so much that she runs away from home.
  • Stars, Eyes of Heaven
    • Joseph Joestar has a tendency to this when recounting the events of Stardust Crusaders to his family, especially when he brags about the plane crashes they've been through. Caesar was not amused.
      Joseph Don't look at me like that Caesar...CAE-
    • His son Josuke isn't much better. After he, Okuyasu, and Koichi finds out that the mysterious man they thought was an enemy was really Jotaro's lover Tenmei Kakyoin, he rambles how he didn't realize since it seemed weirdnote . It doesn't take long for Tenmei to guess that Josuke is Joseph's kid.
      Josuke: Aah! Sorry! I didn't realize! It's just kind of weird! Not the gay part! It's not like I'm not okay that you're girlfriend's a man! Boyfriend! Love who you love, and all that. Just, uh- Jotaro-san didn't... seem... like a love kind of guy? I guess?
  • This Bites!:
    • During the scene in the palace baths, after Cross finishes telling Nami he has too much respect for her to peep on her, she manages to call him up to the wall to talk to him, only to give him an eyeful of Vivi instead. The first thing Cross comments on is whether she's dedicated with the hair dye. Vivi's stool, meet Cross's cranium.
    • When Cross wakes up from Enel's initial attack and sees Conis, he makes a statement about how he wished he could've seen Enel's face when Luffy kicked the crap out of him, thinking that he missed the whole arc... not realizing he was only knocked out for a second and a very unamused Enel is right next to them.
    • Since Usopp never leaves the crew in Water 7, while acting as Sniperking to try to pretend to be someone braver, he essentially states that 'Usopp' deserted from the mission of rescuing Robin without any significant reason. Luffy is not pleased by the implications.
  • In Zero Context: Woolgathering, Ellen Harrison has a moment of this when, after being mistaken for a new initiate, a group of cultists tell her that they plan to summon their warlord dragon master to the park she'd been relaxing in.
    Ellen: ... ...So if I'm understanding you correctly, you're summoning a malevolent world conqueror from the other side of the universe... and being the complete morons you are, you think this is somehow a good idea?
    (Stunned looks from the cultists, and the lead summoner doing a landed-fish impression)
    Ellen: (thinking) ... ...Excellent work, me. Of all the times to fail at keeping your thoughts to yourself, you had to pick now. This is why I hate talking to people.

  • Turning Red: When Jin and Ming find out about their daughter Mei's first red panda transformation, Jin's reaction isn't the most tactful to the cautious Ming.

    Jin: This happened already?
    Mei: What did you just say?

    Ben: Nun soup?
    Newton: BEN!
  • X-Men: First Class: During the climax, Charles desperately tries to reason with Magneto and calm him down after the combined Soviet and American fleets fire on the X-Men after seeing their power, insisting that they're all good, innocent men who are Just Following Orders.

    Magneto: I've been at the mercy of men "just following orders". Never again.

    Doroga: She did not. Hashatnote  had.

  • Jane of the Green Hills series tends to carelessly say whatever she's thinking. She's afraid this will get her in trouble again.
  • Nina Tanleven: In The Ghost in the Third Row:
    • When one of the costumes for the play is damaged, one of the people involved says that "Does it make sense to think it was done by a ghost?

Nine and Chris are confused at the time, but learn why he reacted like he did the next day.

  • Arrow: Felicity Smoak, to the point where Earth-2's Harrison Wells, who literally got kicked out of his universe for having No Social Skills, still has more tact than her.
  • The Barrier: Iván is prone to such moments when drunk or hungover.

  • Coupling: A form of Cannot Talk to Women, by Jeff: just about every time Jeff talks to a woman, he manages to do this. For example, this exchange occurs just when things seem promising:
    Lynda: I like kissing, don't you?
    Jeff: Oh, yeah! Especially the tongues part. I love getting all that extra tongue. You know, sometimes I eat really cold ice cream just so that my tongue goes numb and it feels like someone else's... But then we all get lonely sometimes.

    D.B. Russell: I think the head of the New York Crime Lab knows what a crime lab looks like.
  • Doctor Who: In "The Day of the Doctor", the Tenth Doctor has a bad habit of doing this while talking to Queen Elizabeth I, repeatedly saying terribly offensive or regrettable things under the assumption she was a Zygon duplicate. It gets them married.
  • On ER, Carol's new boyfriend Shep makes some insensitive comments about the suicide attempt patient was brought in, suggesting that "she didn't really mean it" because she took pills as opposed to a more lethal method. Carol snaps, "I really meant it", referring to her own suicide attempt a year earlier in which she herself overdosed on pills (and as a nurse, she would certainly have known what would be a fatal amount) and storms off.

  • Kamen Rider Dragon Knight: Kit says this trope word to word after unknowingly hurting Chris.

    • DiNozzo runs afoul of this trope from time to time as well.
  • In Sherlock, we have Molly.
    Molly: How's the hip?
    Mrs. Hudson: Oh, it's atrocious. But thanks for asking.

  • Star Trek: The Next Generation: During "Hollow Pursuits", Capt. Picard accidentally calls Barclay by his unofficial nickname Broccoli. Data tries to put a positive spin on the situation by referencing psychology but really only makes the situation worse.
  • Schitt's Creek: All the Roses do this occasionally, but Johnny Rose does it all the time. Often, Johnny has every right to assume something he's wrong about, but he still gets blamed and guilted. Examples include when he assumes Alexis is pregnant, when he assumes Ted's mother has a crush on him and when he assumes Patrick's parents know their son is in a relationship with David.
  • Strong Medicine's Dr. Lu Delgado often has moments like this. Sadly, none of them seem to make her realize that she should think before she talks:

    • She's incredibly rude to her son's girlfriend until the girl zings her for hating her for being white rather than for being rich.
    • She's also quite rude to her new partner Andy after she's hired, insinuating that she can't handle working with low-income patients, until Andy reacts like she wasn't even listening to her.
    • She lectures Andy about supposedly exploiting her Eastern European nanny/housekeeper. Andy angrily informs her that she is doing no such thing—she's paying the woman even more than the norm and has taken care of the necessary paperwork.

  • "Postcard Xo" by RedHook:
    P.S. I'm drinking, to drown the failure
    'cause I've fucked up again like you would not believe!
    Guilt like an anchor, pulling me under
    My foot's so far inside my mouth it's hard to breathe!

    Mythology & Religion 
  • Peter from The Four Gospels does this constantly, saying something that he thinks is smart only for Jesus to show him how completely wrong he is. He finally breaks this habit somewhere in the middle of Acts.
    • Also from The Bible: James the Lord's brother spends the middle part of chapter 3 from his own epistle to explain how dangerous the tongue really is.
    Even so, the tongue is a little part of the body and boasts great things. See how great a forest a little fire kindles. The tongue is a fire, a world of evil. The tongue is among the parts of the body, defiling the whole body, and setting the course of nature on fire, and it is set on fire by hell. (James 3:5-6)

  • In Dawn of a New Age: Oldport Blues, Michal asks Ivan upon first meeting him if the acquisition of his superpower took away his voice. When Ivan explains that his lack of voice is a disability that he's always had, Michal is horrified at his mistake and panics so badly that he bursts into flames.

    Lulu: Excuse me?
    Tidus: I know I could never take Chappu's place. You're the one who told Wakka that, right, Lulu? And I don't think Wakka would ever try to take Chappu's pl—
    Lulu: You don't want to finish that sentence.
    • Alphinaud also has this tendency. especially around Y'shtola and his sister Alisaie.
  • God of War (PS4): Prior to the final boss fight, Freya tries to soothe Baldur, telling him that she knows that he's still angry with her, that how he feels hasn't changed...

    Tommy: Wilbur, a large majority of our viewers are American.
    Wilbur: I realized that half-way through the word "Americans"...

    Brian: Oh gosh, I... I didn't know! I'm so... I'm so sorry!
    Quagmire: Oh, you're sorry? F-For what? That waiting in line is such a catastrophe, that you'd rather destroy the confidence of a 5-year-old cancer patient?
    Brian: Aww, come on. I-I didn't know she was dying.
    Quagmire: Who said anything about dying?!

  • This happened in The Life and Times of Juniper Lee: The titular character calls her crush a "total babe with the hair and the cute smile" when he's standing Right behind her. She quickly realizes this. In fact the full sentence is:

  • Steven Universe has a few:
    • Pearl is in fine form in "The Test", first accidentally revealing that the Sea Spire mission was a test, then digging herself deeper when she desperately tries to rectify the situation. Her Oh, Crap! expressions throughout the whole thing are priceless.
    • Peridot. Due to her lack of social skills, she makes crucial blunders time and time again.

In "It Could've Been Great", she praises the original plan that would've destroyed Earth. In "Message Received", the Crystal Gems think she betrayed them due to a lack of communication, and then she completely fails at trying to negotiate with Yellow Diamond. In "Barn Mates", she has a difficult time making her attempts at apologizing to Lapis seem sincere. Fortunately, as she gets Character Development, Peridot seems to suffer this trope much less often.

Video Example(s):

How well does it match the trope?
