Alice and Bob were born and raised in Spain. However, they moved to the States and speak perfect English. One day, Bob decides to prank her. He jumps out of her closet, she freaks out, and in a state of confusion, she starts screaming in Spanish.
Simply put, a character will revert to their native language when emotional. This comes up a lot in media about The Mafia, with Italian-American gangsters throwing in some Italian at moments of high excitement.
Unlike Hiding Behind the Language Barrier, Insulting from Behind the Language Barrier, Teasing from Behind the Language Barrier, and Language Fluency Denial, this switch is unintentional and may also be in Bob's native language.
Foreign-Language Tirade is a Sub-Trope, specifically for angry language shifting.
Compare Accent Slip-Up, where the reversion is to a different accent rather than a completely different language.
May overlap with Foreign Cuss Word if cuss words are involved or Pardon My Klingon if the language is fictional.
Bilinguals and multilinguals will realize that this is Truth in Television.
Examples:
- Gargantia on the Verdurous Planet: Ledo has to painstakingly learn the Earth peoples' language over the course of the show, but by episode 8 he is reasonably competent with it. Then, when he tries to explain the hostility between the Galactic Alliance and the Hideauze, he gets rather emotional and lapses back into his native tongue all of a sudden, leaving Chamber to do the translating.
- Hellsing: Pip yells a bit of his French while complaining that Seras and Alucard get a fancy penthouse suite in a fancy hotel while he's stuck in a cheap motel. "Oh, the iniquity! Damn you, bourgeoisie! Damn you!"

- Ooguma from Miss Kobayashi's Dragon Maid screams "Yo no tener dinero!! No tener dinero!!"note when the dragon trio tries to get her to let them live with her, having mistakenly took them for muggers. This serves as one of several bits of foreshadowing to her true identity as a reincarnation of the Aztec god Tezcatlipoca, given the fact that she's otherwise stated to be 100% Japanese.
- My Hero Academia: One of the students of Class 1-B, Pony Tsunotori, is half Japanese and half American; unlike similar characters in other anime and manga, Japanese is explicitly not her first language. So not only does she speak Japanese with a noticeable accent and often substitute Japanese words for English ones, she is also noted to switch to speaking English whenever she is angry or upset.
- In a fourth season episode of Ojamajo Doremi, Momoko is so shocked when she figures out Hana secretly transformed into Onpu so she could rest she verbally panics in English (which isn't her first language, but one she grew up with to the point she became more fluent in that than Japanese when she's introduced). Naturally, the others can't understand what she's trying to say, forcing her to follow Hana alone.

, Vincento briefly switches to his native Spanish in his excitement after Shura tells him she loves him.
- In Galactic Romance, though Rat is fluent in Russian and the Cosmolingua, he can switch to his native Krokrys language when he's feeling particularly emotional, which can be awkward for Alice who doesn't know the language. In particular, in Starship on a Grill, when their son has just vanished and Rat goes to search for him, he tells Alice to stay behind but doesn't realize he says it in Krokrys and she doesn't even understand him (not that it would have made any difference if she did).
- Lost in Translation: When Vegeta confronts Bulma after she walks in on him and Kakarot having sex and tries to swear her to secrecy, his panic about the situation causes him to switch between the Earth language and his native Saiyan tongue mid-sentence.
- Megami no Hanabira: Brother George's reaction to Matador appearing right in front of him is to run away as fast as he can, screaming in English the whole time. For reference, the story takes place in Japan, and most of the people there, including George himself, speak Japanese.
George: LET ME OUT! LEMME OUTTA HERE! LET ME OU-!
- New Vegas Showtime has the Japanese cast of Persona 5 end up in the Mojave Wasteland. Futaba reacts to being told she's in the early 2280s with a "Nani?" ("what?"), Ryuji blurts out a "ittai nan da?" ("what the heck?") when witnessing the Think Tank for the first time, and Akira fails to switch to English ("Dōshi- gah, I mean, why?") around the fresh corpses of raiders killed by Makoto.
- In This Bites!, Cross asks Soundbite to bite him on the neck so he wouldn't say something incriminating when he learns that Kaku and Kalifa had joined Iceberg to meet with the Straw Hat Pirates and Franky. Of course, the agony of Soundbite's teeth crushing him causes him to shout a Cluster F-Bomb in French.
Cross: YEARGH! MAUDIT PUTAIN D'UN ESPÈCE DE SALAUD SALOPARD QUI BRÛLE DANS LE MAUDIT ENFER AVEC UN SEAU DE—SOMEBODY GET THIS LITTLE SHIT OFF OF ME, DAMN IT!

- Inverted in The Parent Trap (1998) when Annie (as Hallie) gets stressed and starts babbling in French. As a rich girl raised in England, it makes sense that Annie would learn French, but she's impersonating Hallie, who was raised in the California wine country, someone who has no reason to know French. When her father expresses his shock, she tells him that she "picked it up" at the 8-week summer camp she's just returned from.

- Leo Rosten tells this one in The Joys of Yiddish:
The special flavor of gevalt! is expressed in the story of the apocryphal Countess Misette de Rothschild, half-French, half-English, who lay in childbirth in the magnificent bedroom of her mansion off the Champs-Elysées, moaning and wailing. Downstairs, her husband, the Count, wrung his hands anxiously.
"Come, come," said the obstetrician. "She's not ready to deliver. Let's play cards. There's plenty of time."
They played cards for a while.
From above, came the shrill cry of the Countess: "Mon Dieu! Mon Dieu!"
The husband leaped up.
"No, no," said the doctor. "Not yet. Plenty of time. Play."
They played on.
Soon the Countess screamed: "Oh, God, oh God!"
Up leaped the haggard husband.
"No," said the doctor. "Not yet. Deal."
The husband dealt... they played on.
Came a resonant "Ge-valt!"
Up rose the obstetrician. "Now."
- In Alex Rider: Ark Angel, Nikolai Drevin starts babbling in Russian after accidentally shooting his son.
- Baka and Test: Summon the Beasts has Minami who when shocked, loses the ability to speak Japanese and begins to spout gibberish in German (since despite being Japanese, she spent most of her life in Germany). It takes a while before she calms down.
- The French Renaissance philosopher Michel de Montaigne spoke Latin as a first language and never learned French until he was about six. He continued to speak and write in French to the point where he forgot much of the Latin he learned, but in his essay "Of Repentance", he admits this:
"We do not root out these original qualities, we cover them up, we conceal them. Latin is like a native tongue to me; I understand it better than French; but for forty years I have not used it at all for speaking or writing. Yet in sudden and extreme emotions, into which I have fallen two or three times in my life—one of them when I saw my father, in perfect health, fall back into my arms in a faint—I have always poured out my first words from the depths of my entrails in Latin; Nature surging forth and expressing herself by force, in the face of long habit. And this experience is told of many others."
- Mentioned via aversion in Tarnsman of Gor (the first in the Gor series). Tarl and his trainer (also named Tarl, aka "the older Tarl") realize his fluency in Gorean is proceeding apace when he doesn't switch to English.
Tarl: I had begun to dream in Gorean...I was fluent in Gorean. Once, when struck by the Older Tarl, I had cursed in Gorean, and he had laughed.
- How NOT to Write a Novel: Parodied, with its example of how not to write characters who speak in a foreign language, involving a Yellow Peril villain whose speech devolves into the extent of the fictitious author's very limited understanding of "Asian" language: a takeout menu.
"Bok choy!" cried Fred Cho, evil mastermind of the mad squid outbreak, as he burst into the room, waving his .38 Wabash. "Kimchi bok bok!" Spluttering with rage at the scuppering of his bio-plot, he had lapsed into imprecations in his mother tongue.

- The Trials of Apollo: After hearing the news about Jason's death, Nico responds with "Oh, scusatemi"note before hurriedly walking away. His boyfriend, Will, is surprised, telling Apollo that Nico only lapses back to Italian if he is extremely upset.

- CSI: NY: Happens several times with Greek. Generally out of anger, but there are also some non-angry examples:

- In Generation Kill, one of the Marines is a Brazilian immigrant who sometimes switches to speaking his native Portuguese when he's under stress.
- House of the Dragon: Riders usually give commands to their dragons in High Valyrian. However, the Targaryen kiddos mostly know Valyrian in a patchy, heritage speaker capacity. The language they're most comfortable in is the Common Tongue (which is either identical to or represented as English). In the Season 1 finale, Luke and Aemond start freaking out and losing control of their dragons. At first they give commands in Valyrian and then, in their panic, they revert to Common and give commands in that. This is particularly unhelpful because their dragons don't know how to take commands in Common.
- I Love Lucy: Ricky often speaks rapid-fire Spanish, usually when he's exasperated by one of Lucy's Zany Schemes.

- In the Star Trek: Voyager episode "Ashes to Ashes" a dead Voyager crew member was "adopted" by an alien species. Their way of procreating involves reviving corpses and somehow physically turning them into one of their own.

It slowly turns out that this isn't going to work, hinted by the fact that she begins to lapse into her adoptive parents' language when stressed.
