Hello, Troper. Would you like to know about the Trigger Phrase? Good. Then just sit back and relax.

The Trigger Phrase is a post-hypnotic suggestion used primarily in SpeculativeFiction. The phrase can activate a DeepCoverAgent or ManchurianAgent, so hidden that the person may not even know they are an agent. The phrase can practically be anything, even a [[MusicalTrigger piece of music]]. It's like a BrownNote specifically programmed into an individual.

Are you feeling okay, Troper? Do you wish me to continue? Good.

The Trigger Phrase may also be used to activate latent physical prowess (or, to use the layman's terms, "asskicking"). A BerserkButton that not even the characters themselves know about, used when situations are about to get [[LetsGetDangerous dangerous]]. Sometimes, it will help them [[MemoryGambit remember something]].

Is everything all right, Troper? There is no need to go on. There is only one thing left to say about the Trigger Phrase. And that's this:

''In each shadowy corner there lurketh a ghost.''

Are you feeling relaxed, Troper? Good. There is something I need you to do...


[[folder:Anime & Manga]]
* Agents of the Schwarz organization from ''Manga/MaiOtome'' are triggered when they receive a letter in a black envelope.
* [[spoiler:Gwen Khan]] uses two on Melfina in ''Manga/OutlawStar''. "It was you who broke my Meissen plate" deactivates her, while "Breakfast is signaled with a silver spoon" undoes it.
* Ironically inverted in ''Manga/GunsmithCats''. [[FoeYay Mafia boss]] [[PsychoLesbian Goldy]] brainwashes her assassins into blind devotion with a designer drug named "Special K" that renders users highly susceptible to suggestion, so no phrase is needed. However, while she's working over heroine Rally Vincent, the latter [[HeroicSpirit manages an escape attempt while still under the drug's influence]], during which she programs a trigger phrase into herself to ''counter'' Goldy's influence. The ironic part is that it's not a spoken phrase, but [[spoiler:the distinctive sound of the trigger on her highly-customized personal pistol being pulled. How's ''that'' for a literal interpretation?]]
* One example forms the basis of the plot of {{Suehirogari}}'s [[{{Hentai}} ero-manga]] ''TAG'' -- the main character, her friends, and a large number of other victims are all given a post hypnotic suggestion by a gypsy fortune teller they visit: Whenever they are kissed by a naked woman, they [[TheNudifier find themselves stripping nude and staying that way]] until they can kiss another woman who is also affected by the hypnotic suggestions and pass on the condition. In other words, it's a hypnotically enforced game of [[ExactlyWhatItSaysOnTheTin tag]] where "it" has to stay naked. Until they do pass it on, [[AndIMustScream their bodies won't let them even touch clothing]] despite themselves. This also means that the victim they kiss [[TheVirus has to stay naked next...]]
* Done in chilling fashion in ''Anime/{{Noir}}'', in which Chloe deploys Kirika's "True Noir" personality by saying "receive the final guidance" - ''and then shooting her.''
* ''Manga/MahouSenseiNegima'' doesn't actually have this occur (yet), but when the cast are dealing with a ManchurianAgent in their midst, [[DiscussedTrope the team mercenary notes that they can't rule out the possibility of a Trigger Phrase]].
* The [[LaserGuidedTykebomb Extended soldiers]] in ''Anime/MobileSuitGundamSEEDDestiny'' each possess a "Block Word" which is supposed to rein them in. However, in practice the phrases simply seemed to drive the Extendeds into a terrified frenzy. Also crosses over into ThePasswordIsAlwaysSwordfish, since the Alliance chose stupidly common words - "[[spoiler:die/death]]" for Stella and "[[spoiler:mother]]" for Auel (we never learn what Sting's is).
** WordOfGod indicates that Sting's Block Word is "[[spoiler:dream]]", continuing the program's very poorly-thought-out trend of using extremely common words to detonate their {{Tykebomb}}s.
* An important part of the plot in ''Anime/LastExile'' concerns the hunt for [[PlotCoupon four of these]], along with [[LivingMacguffin the girl they trigger]].
* In ''Anime/CodeGeass'', Lelouch uses time-delay geass commands regularly, for various stimuli, including a speech he would later give, a series of motions in combat and a hand position.
* A variation appears in ''Manga/JoJosBizarreAdventureStoneOcean'': [[spoiler: DIO's diary describes a sequence of fourteen secret, nonsensical phrases [[labelnote:*]] Spiral staircase, rhinoceros beetle, ghost town, fig tart, rhinoceros beetle, Via Dolorosa, rhinoceros beetle, singularity point, Giotto, angels, hydrangea, rhinoceros beetle, singularity point, secret emperor[[/labelnote]] that, according to the diary, are necessary to "achieve heaven". Indeed, BigBad Enrico Pucci utters this sequence of words to Green Baby, which then fuses with his Stand Whitesnake to form C-Moon.]]
* Anime-exclusive Ijuinn Kotaro of ''Manga/RosarioToVampire'' has the magical ability to make anybody fall in love with him and obey him by uttering "''Je t'aime''!" ("I love you!" in French).
* Sayer of ''Anime/YuGiOh5Ds'' says "The entrance to the Underworld is on the witch's island" to Akiza, which unleashes the [[SuperpoweredEvilSide Black Rose Witch]].
* In ''Manga/{{Doubt}}'', [[spoiler:Mitsuki's]] BrainwashedAndCrazy persona is activated when hearing the phrase, "For the one I love."

[[folder:Comic Books]]
* "Croatoa" from ''ComicBook/OneHundredBullets''.
* "Kimota" functions as this in the first issue of ''Comicbook/{{Miracleman}}'', instantly restoring the hero's memories when he says it.
* In ''Comicbook/JusticeLeagueInternational'', the despotic ruler of Bialya, the Queen Bee, triggers Blue Beetle with the phrase "Bialya, my Bialya." Once the heroes have figured out what is going on, it's not very difficult to determine the responsible party.
* ''[[Comicbook/TeenTitans Teen Titans Spotlight]]'' featured a superhuman psychiatrist who was brainwashing her clients into becoming secret assassins; she used the trigger words "Goldilocks", "Rumpelstiltkin", and possibly "Snow White" to activate and deactivate them.
* "He loves you" in both ''ComicBook/SecretInvasion'' and the ''ComicStrip/TwistedToyfareTheatre'' parody of same. "He loves you." "Who, Northstar? I know, it's just--HEY!"
* Franchise/{{Batman}} set up an alternate "[[CrazyPrepared emergency personality]]" for himself that was triggered by the phrase "Zur En Arrh." This is taken from a story in ''Batman'' #133 in 1958 where Batman encounters his crimefighting counterpart from the planet Zur-En-Arrh. In the context of the story, it is revealed that the phrase is [[spoiler:a bastardization of Thomas Wayne's last words, "Zorro in Arkham."]]
** Batman had another self-administered version in a ''[[JusticeLeagueOfAmerica JLA]]'' storyline. [[spoiler:He was designing weapons to take out his own teammates if necessary. In order to keep the project hidden from Martian Manhunter's telepathy, he had the knowledge of his plans mentally "buried," and it could only be recalled when he heard a trigger phrase from his bat-computer. A different trigger phrase would "re-bury" the project in his subconscious if MM came within telepathy range of the Batcave.]]
* In the ''Dethklok vs. ComicBook/TheGoon'' one-shot, General Krozier activates Dr. Rockso's programming to kill Dethklok with the nonsense phrase "peaches valentine." This just happens to be the name of a character in ComicBook/TheGoon. Hilarity (and murder) ensues.
* ReformedButNotTamed ComicBook/XMen former villainess ComicBook/EmmaFrost used her powers to shut down two armed guards' pain centers after a fight with Wolverine, which seems like a nice thing to do, but then she stuck something extra in:
-->'''Emma Frost''': "And every time you hear the words 'parsley', 'intractable' or 'longitude' you will vomit uncontrollably for 48 hours."
** Emma used this same trick in ''[=A+X=] #13'' while on a personal mission with Black Widow, with a slight twist to it. Rather than a trigger phrase, she used her telepathy to implant a pervert (by the name of Frank) who was blackmailing her with a supposed sex tape with a trigger ''sight''. Now, every time he sees a pair of bare breasts, he projectile vomits. ''[[UpToEleven Every time.]]'' Natasha finds it so amusing that she feints having left something behind just to go back and flash the guy again.
-->'''Black Widow:''' I ''forgot'' something, just be a second.
-->'''[[AssholeVictim Frank]] (Offscreen):''' BLOOORRRCHHHH!!!
-->'''Emma:''' What'd you forget?
-->'''Black Widow:''' I just ''[[ForTheLulz had]]'' [[ForTheLulz to see that again.]] Some things just ''never'' get old.
** In the same series, ComicBook/{{X 23}} has a trigger ''scent.'' DependingOnTheWriter, she's either learning to fight it or is instantly turned into an AxCrazy berserker who will kill the person marked with the scent (or sometimes pretty much anyone in the vicinity) without hesitation.
* ''Comicbook/UltimateSpiderMan'''s Norman Osborn set up "Cellar Door" as an all-purpose trigger phrase for his son Harry.
* ''ComicBook/TheAuthority'': the military-industrial complex who built Seth, the hillbilly cyborg killing machine with [[SuperpowerLottery over 1,000 super powers]] naturally set up a four-word kill-switch phrase. [[spoiler:It's never actually used. Instead, the team's RealityWarper alters history so a less aggressive American administration came to power, and thus Seth was never created. "Welcome to the Oval Office, President Gore."]]
* During the ''ComicBook/TeenTitans[=/=][[ComicBook/BatmanAndTheOutsiders Outsiders]]'' crossover "The Insiders", Superboy was brainwashed by Lex Luthor, who used the words "Vincere Aut Mori" ("Conquer or die" in Latin).
* In one [[WhatDoYouMeanItsForKids surprisingly disturbing]] [[ComicBook/MickeyMouseComicUniverse Mickey Mouse comic]], the trigger word is "time". The villain (a psychologist, who sought revenge on Mickey for putting his son in jail) deliberately chose a fairly common word, so the trigger would go off often enough. It made Mickey instantly fall asleep and have nightmares, causing him to be unable to tell reality from dream and eroding his confidence.
* Occurs in ''ComicBook/TransformersMoreThanMeetsTheEye'' While digging around Decepticon Super Warrior Overlord's mind for information, Chromedome implants the phrase "Til all are One" on the off chance that if Overlord broke free (which he does) and if Rodimus says the phrase (''[[CatchPhrase which he will]]''), there would be some way to stop him. The phrase triggers Overlord's intense fear of failure, briefly rendering him helpless and unable to fight.
* In ''ComicBook/{{Violine}}'', the word "fatalitas" is used as a trigger to snap someone out of hypnosis.

[[folder:Comic Strips]]
* In ''ComicStrip/LibertyMeadows'', Brandy demonstrates a trigger on Leslie. With a snap of her fingers, he puts the rehab-breaking Dean in a headlock. "SLEEPER HOLD! DAAAAAH!"
* ''ComicStrip/ModestyBlaise'': The phrase 'Rip Van Winkle' is used to put a millionaire into a trance as part of TheCon in "The Girl from the Future".

[[folder:Fan Works]]
* In ''Fanfic/KyonBigDamnHero'', Haruhi gives Kyon one of these [[spoiler:in case he ever needs to undo her MemoryGambit]].
* When Darrel is drugged in ''FanFic/RWBYReckoning'', the phrase "[[ChessMotif Queen calls the knight]]" puts him under the control of [[spoiler:Cinder Fall]], while the counter phrase is "Time to wake up".
* In ''[[https://www.fanfiction.net/s/8429437/28/The-Perils-of-Innocence The Perils of Innocence]]'' a memory-charmed Dumbledore remembers that the Potters switched Secret Keepers when Sirius shouts "Now is the time for all good men to come to the aid of their country" during his much-delayed trial.

* ''Film/{{Serenity}}'': River is activated by a subliminal message in a Fruity Oaty Bar commercial, but is [[spoiler:put to sleep]] by Simon saying "Eta kuram na smekh," Russian for "That's for hens to laugh at" (i.e. "That's ridiculous.")
* The original version of ''Film/TheManchurianCandidate'' has both a Trigger Phrase ("Why don't you pass the time by playing a little solitaire?") and a Trigger Card: the Queen of Diamonds.
** In the remake the [[ManchurianAgent agents]] get personalised triggers: [[spoiler:their names and old ranks, phrased in the form "Sergeant Shaw. Sergeant Raymond Shaw. Raymond Prentiss Shaw."]] And later...[[spoiler:[[TomatoInTheMirror Major Marco. Major Bennett Marco. Bennett Ezekiel Marco.]]]]
** But what if [[spoiler:they don't have a middle name]]?
* ''Literature/TheLatheOfHeaven''. George Orr is hypnotized so his "effective" ([[RealityWarper reality changing]]) dreams can be controlled. The Trigger Phrase is "Antwerp."
* ''Film/{{Telefon}}'' (1977). KGB sleeper agents in the U.S. were brainwashed via drug-induced hypnosis to forget their true identities and live as Americans until they heard a line from Robert Frost's poem "Stopping by Woods on a Snowy Evening", followed by their Russian names. When they heard it, they would destroy a pre-programmed target and then kill themselves. The Trigger Phrase was:
-->"The woods are lovely, dark, and deep, but I have promises to keep. And miles to go before I sleep. Remember miles to go before you sleep."
** The technique is demonstrated for Charles Bronson's KGB protagonist using the phrase "Cleopatra says there will be snow from the west." This is the scene being spoofed in the first ''Film/TheNakedGun'' movie (where the beeping of a watch was the trigger) when Vincent Ludwig's secretary tries to shoot Pahpshmir with an empty gun.
* ''Film/TheIpcressFile'' (1964). "'''Now listen to me'''. Shoot the traitor [[spoiler:Ross]]." Fortunately Michael Caine's character was not in the brainwashing chamber long enough, so is able to 'distract' himself by striking his injured hand against the wall, then shooting the ''real'' DoubleAgent.
* In ''[[Film/AIArtificialIntelligence AI]]'', speaking a trigger phrase will cause an android child to permanently and unconditionally love the speaker.
* Derek Film/{{Zoolander}} will kill the Prime Minister of Malaysia when he [[MusicalTrigger hears the song]] ''Relax''.
* "Constantinople" and "Madagascar" in ''Film/TheCurseOfTheJadeScorpion''.
* The toggle for Hawkin’s fencing abilities in ''Film/TheCourtJester'' is a snap of the fingers. OK, not exactly a phrase, but if music counts…
* "Freeze!" and "Bullshit" in ''Film/NowYouSeeMe''.
* In ''Film/TheHotRock'', a bank guard is hypnotised into handing over the diamond upon hearing the phrase "Afghanistan banana stand''.
* ''Film/PrettyCool'' and [[Film/PrettyCoolToo its sequel]] love this.
** "You two will have the most intense orgasm you've ever felt, when you hear the word 'now'."
** "Whenever you talk about money, you will play with your boobs, and not even know you're doing it."
** "The Big O will happen to you whenever you hear the word "in", and will stop whenever you hear the word "out"."
* ''Film/AmericanUltra'': "Chariot progressive listen. Mandelbrot set is in motion. Echo Choir has been breached, we are fielding the ball." Subverted in that the target responds only with utter bafflement. [[spoiler: Double Subverted when, soon after, he effortlessly (and much to his surprise) kills two assassins sent after him.]]
* ''Film/CaptainAmericaCivilWar'' reveals that the Winter Soldier had a string of trigger words, used by HYDRA before missions as something of a reset code to see that he was still obedient to them and did not remember his previous identity. [[spoiler: It's revealed that they still work perfectly, ensuring Zemo successfully reverts Bucky to an obedient fighting machine for a short time. For the curious, the words are "Longing, rusted, seventeen, daybreak, furnace, nine, benign, homecoming, one, freight car," in Russian and in that order. The Soldier replies "Ready to comply," also in Russian.]]
* In ''Film/GetOut2017'' the villain hypnotized TheHero one night [[OrWasItADream he thought he had a bad dream]] and implanted the command whereupon any time he heard the sound of a spoon clinking a teacup three times, [[AndIMustScream he would collapse onto the floor, paralyzed, while his consciousness fell into the "Sunken Place."]]

* The ''Franchise/{{Dune}}'' franchise likes this trope.
** In ''Literature/{{Dune}}'', the Atreides slave gladiator who fought Feyd-Rautha Harkonnen received a post-hypnotic suggestion to have his muscles go slack when he heard the word "scum". The Bene Gesserit also do this to people they consider dangerous: one Trigger Phrase they use is "Uroshnor".
** [[Literature/DuneMessiah "She is gone."]] Upon hearing that, [[spoiler:Hayt is supposed to kill Paul. He refuses, awakening the memories of Duncan Idaho]].
** [[Literature/ChildrenOfDune "Secher Nbiw."]] Spoken by Leto II it causes [[spoiler:Ghanima's self-induced mental 'dam' to break, restoring her correct memories and freeing her from the threat of possession]].
* In ''Literature/DirkGentlysHolisticDetectiveAgency'', Dirk hypnotizes Richard, and implants the suggestion that whenever he hears the phrase "my maiden aunt from Winnipeg" he should immediately take off all his clothes and jump in the nearest canal. It's a roundabout way of making a point about ghostly possession and free will.
* Creator/DeanKoontz novel ''Night Chills''. People implanted with conditioning through subliminal hypnosis are activated when they hear the Trigger Phrase "I am the key." They then reply, "I am the lock."
** Koontz uses this again in ''Literature/FalseMemory''. The villain has different trigger phrases for each person under his control, in the form of haiku. He speaks a name, the subject replies "I'm listening", then he gives each line of a haiku, with the subject giving a programmed response to each line in turn.
* Creator/RobertAHeinlein:
** ''Literature/StarshipTroopers''. Mobile Infantry troopers are given a post-hypnotic suggestion to go to sleep upon hearing the Trigger Phrase "Prepare to sleep, one, two, three."
** ''Literature/CitizenOfTheGalaxy''. Thorby Baslim is hypnotically conditioned to memorize several different messages, so he can repeat each one to a specific starship captain. The man who conditioned him tested Thorby's recall of each message using the Trigger Phrase of the name of each captain and ship.
* In the book that is sometimes called the TakeThat to ''Literature/StarshipTroopers'', ''Literature/TheForeverWar'' has a hypnotic phrase that is used on the conscripts for their first battle, as the military command isn't confident that they will kill the enemy. It works ''too'' well, as the soldiers start blasting everything in sight.
* A B-plot in one of the ComicBook/XWingSeries books is the presence of several brainwashed assassins throughout the New Republic: each has their own trigger phrase, all somewhat bizarre. "Wedge Antilles hops on one transparisteel leg" means "Kill Wedge Antilles," for instance. "The Wookiees are dancing in the parlor" means "Kill everyone between you and Admiral Ackbar, then kill him." Apparently the triggers are different for everyone. A later book has a man sent to deliver a message simply by his presence - he's been known to be in a secret prison for years - with a device implanted that floods him with poison, killing him instantly. The device is triggered when someone recognizes the man and says his name.
** [[ReverseMole Kirney Slane]] uses a trigger phrase to load the backup memory of her astromech droid, Tonin, which she had wiped shortly before her infiltration. (The phrase is the full definition of Tonin's name.) This is part of an [[InvertedTrope inverse]] MemoryGambit, and one that Slane hadn't really liked doing to Tonin; it's implied that Tonin doesn't mind too much (and may have consented to this treatment to begin with).
* In ''[[Literature/WaysideSchool Wayside School Gets a Little Stranger]]'', the school has a hypnotist guidance counselor who cures people of whatever it is they've been sent to him for, but also implants an unrelated trigger phrase just ForTheEvulz. In the chapter "[[ContentWarnings A Story with a Disappointing Ending]]," Paul gets sent to him for pulling Leslie's pigtails and is hypnotized into thinking they're deadly rattlesnakes... and also that when she says the word "pencil" her ears will turn into delicious candy which he must try to eat. He's snapped out of it and sent back to class, and the hypnotism successfully prevents him from pulling Leslie's pigtails. Then she breaks her pencil. She two classmates have a whole discussion about it without using the word "pencil," even though Paul interjects twice asking what they're talking about. [[BrickJoke Several chapters later]], the class is dropping objects out the window to prove that everything falls at the same speed, including a pencil sharpener. Because everyone's been saying "pencil sharpener" throughout the chapter, you think nothing of it at the end when Leslie does...
* In ''The Miserable Mill'', part of ''Literature/ASeriesOfUnfortunateEvents'' the word "Lucky" is used as a trigger to the point of parody, since the good guys catch onto it and both sides flip [[spoiler:Klaus]] back and forth in obeying their commands. The word "Inordinate" deactivates the state.
* The eleventh book of ''Literature/TheDresdenFiles'', ''Turn Coat'', features one of the antagonists using the Trigger Phrase "The end is nigh." to take control of several [[spoiler:Wardens and members of the White Council of Wizards]].
* In the YA novel ''Literature/TheAdorationOfJennaFox'', Jenna [[spoiler:was, after a nearly fatal car accident, placed into an artificial body with a reconstructed "brain" made of computer chips, which was programmed with a trigger phrase as a "suggestion" to use in case anything went wrong: "Go to your room, Jenna." If said, this phrase would [[ExactlyWhatItSaysOnTheTin cause Jenna to automatically walk to her room]], whether she wanted to or not - though she learns to resist it eventually.]]
* In Creator/JamesSwallow's ''TabletopGame/{{Warhammer 40000}}'' short story "The Returned", the Doom Eagles fear that Tarikus, even pure of taint in mind and body, might still have taint in his soul, which might be triggered by a phrase.
* Becomes very important late in the ''Literature/HonorHarrington'' series, though with Trigger conditions rather than phrases. The control affected by the nano-tech is so complete that it can convince the personal bodyguard of an Andermani Royal to kill the man he's guarding, to convince a Manticoran flag lieutenant to kill his flag officer, and convince a man to commit suicide by Mach 2 impact into a cliff-wall while in his air-car. Even worse, the victims are [[AndIMustScream aware of what they're doing and unable to stop themselves from acting]].
* In the Emily Rodda novel ''[[Literature/RowanOfRin Rowan and the Keeper of the Crystal]]'', it is revealed in the end that [[spoiler:Doss]] had been brainwashed by the Zebak years previously, the trigger phrase being the words that [[spoiler:officially made him Keeper of the Crystal. He got better.]]
* In the book ''Literature/TheHotRock'' by Donald Westlake, the gang hires a specialist (a hypnotist) to plant the phrase "Afghanistan banana stand" in the mind of a bank employee. Later, one of the gang enters the bank and says this, and the employee helps them to retrieve the [[MacGuffin eponymous gem]].
* Used in ''Literature/TheStand'', Glen telling Tom "it's time" as in 'time to go West', after hypnotizing him earlier.
* In ''Literature/MortalEngines: Infernal Devices'', a [[{{Cyborg}} Stalker]] is programmed to assassinate the leader of the Green Storm when it hears the phrase "The moment of the rose and the moment of the yew tree are of equal duration".
* ''Literature/{{Mindwarp}}'' has a character, a time-traveler named Toni, whose powers first trigger when trying on a dress, looking at herself in a changing room mirror. She travels back in time eight years for a little while, then returns to the present outside the store, and gets busted for shoplifting. Later at home, she tries the dress on again and goes back in time eight years to when she was five and her mother was still alive. After speaking together, the mom calls in five-year-old Toni and implants a hypnotic command to come back to this day when seeing 13-year-old Toni in that dress. Later, she uses her mugshot from her shoplifting arrest to escape a jam, and rearm in the mall.
* In ''Literature/TheSouthernReachTrilogy'', the psychologist implanted the expedition members with post-hypnotic suggestions, which she can activate using trigger phrases woven into her speach.

[[folder:Live-Action TV]]
* ''Series/GetSmart'':
** One episode where the agent is Max and the trigger is "Checkmate." Max is meant to challenge his target, The Chief, to a chess game and then shoot him when he loses (given that Max is too incompetent to win). Unfortunately Max dithers so much during the game, that when he finally does lose an exasperated KAOS DoubleAgent in the room shouts "Checkmate!" in delight, and gets shot instead.
** The follow up joke in the epilogue is that even after Smart realizes this manipulation at the end of the story, The Chief finds out the hard way that Smart is ''still'' reflexively shooting at any one saying "Checkmate," and Smart has to sheepishly explain that a bad habit is hard to break.
** In another episode, Hymie is reprogramed to shoot Max when he asks for the check. But Max asks for it in Spanish, and when Hymie translates for the girl with them (saying "check" in English), he promptly shoots himself.
* ''Series/{{Dollhouse}}'': Activates: [[spoiler:"There are three flowers in a vase. The third flower is green."]] Deactivates: [[spoiler:"There are three flowers in a vase. The third flower is yellow."]]
** Dollhouse has a few of these. Most used is simply "would you like to go for your treatment?" or "it's time for your treatment" which is said to an engaged Active by their handler. This immediately makes the Active stop what they are doing and go with their handler back to the Dollhouse to be mind-wiped. PlayedForLaughs in a DeletedScene where Ballard tries using the phrase to stop November, who's been programmed as a tough BountyHunter.
--->'''Ballard:''' You need therapy.
--->''(November slugs him in the face)''
--->'''Boyd:''' Treatment. You need a "treatment".
--->'''Ballard:''' [[ComicallyMissingThePoint No, I'm fine]]. ''(collapses)''
** Also often used are the trust passwords between handler and Active. "Do you trust me?" "With my life." "Everything's going to be alright." "Now that you're here."
** This exchange could count, though it's initiated by the triggeree - used whenever an Active is reset to "tabula rasa":
--->'''Active''': Did I fall asleep?
--->'''Handler''': For a little while.
--->'''Active''': Shall I go now?
--->'''Handler''': If you like.
* ''Theatre/TheOddCouple'': "The fault lies not with the stars but with ourselves" made Oscar neat, and a finger-snap made him back to normal.
* In ''Series/BigWolfOnCampus'', Tommy is brainwashed by the Evil Werewolf Syndicate to obey any command preceded by two specific, secret words. Due to a badly-timed minion interruption, those words end up being "Pizza's here." (Yes, hilarity does ensue.)
* ''Series/NowhereMan''. The episode "Marathon" used "It's a lovely day" or "It's a nice day" (it's been a while since I saw it) spoken over the telephone to activate a ManchurianAgent killer.
* ''Series/BlakesSeven''.
** The location of [[BlackSite Star One]] is revealed by saying the phrase "A fool knows everything and nothing" (the co-ordinates were [[NeuroVault implanted in the mind]] of the Charl's Fool).
** When providing a spacecraft for renegade officer Travis, Servalan orders the cyborg crew be mind-wiped and programmed to respond to the orders of the man who gives the word [[RogueAgent "Outlaw"]].
* In season seven of ''Series/BuffyTheVampireSlayer'', Spike's trigger is a song his mother used to sing when he was a child, the English folk song "Early One Morning".
* A telepathically delivered Trigger Phrase revealed [[spoiler:Talia Winters]] as a sleeper assassin in ''Series/BabylonFive''.
* In the ''Series/DueSouth'' episode "Seeing Is Believing", Fraser hypnotizes most of the other main characters in order to [[RashomonStyle reconcile their accounts of a murder]]. He takes the opportunity to give trigger phrases to both Ray and Inspector Thatcher, making Ray apologize when he says "cauliflower" and Thatcher agree with him when he says "eggplant".
* In one episode of ''Series/MacGyver1985'', Pete gets brainwashed into shooting whoever utters the trigger phrase "From the bottom of my heart, I salute you". The BigBad wanted to use him to kill a visiting dignitary (who was scheduled to give a speech containing that phrase at a dinner Pete would be attending).
* In one episode of ''Series/TheNewAdventuresOfBeansBaxter'', Beans is given the task of babysitting a robot, which becomes an unstoppable killing machine when it hears its trigger phrase. The phrase was designed to be the least likely thing for a person to say ("M. I. N. D. Mood"), but Beans had a dental appointment earlier and his mouth was numbed-up. When his girlfriend asked him if he was in the mood to make out, his slurred answer just happened to match the robot's trigger phrase.
* In the ''Series/{{Hyperdrive}}'' episode "Convoy", the trigger word that puts Henderson under the control of the Scrane is "horrage", defined by them as the [[{{Portmanteau}} combination of hope and courage]].
* PlayedForLaughs in ''Series/{{Night Court}}''. Bull Shannon is due to appear on a game show but is nervous, so his friends hypnotise him so he will remain calm when he hears a Trigger Phrase which is...unfortunately the lecherous DA Dan Fielding choses that moment to say "I want to be your love slave!" to an attractive prison officer. Ironically Bull handles the game show quite well but Dan, not realising this, rushes onto the stage and shouts "Bull, I want to be your love slave!" on live television. At a press conference Dan excuses his actions by saying he was kidnapped and brainwashed by Soviet agents.
* Used in an episode of ''Series/{{Cheers}},'' where it turns out that Frasier has implanted some in Lilith. "Tambourine" causes her to strip, and "tractor" makes her sing.
* ''Series/DoctorWho'' has the phrase, "I am the Doctor and you are the Daleks!" for a group of Dalek deep-cover {{Manchurian Agent}}s.
* ''Series/FatherBrown'': In "Sins of the Father", the murderer hypnotises one of his patients into going into a trance whenever he hears a particular piece of music and killing whoever is playing it, and then sends the sheet music to the man's son to practise for a music competition. He did not foresee his patsy later coming on someone else playing the same piece of music.
* In Series/AgentsOfSHIELD, Whitehall's HYDRA brainwashing is activated by the phrase:
--> '''HYDRA Agent''': Take a deep breath. Calm your mind... Compliance will be rewarded.
--> '''Subject''': I am happy to comply.
* In one ''Series/ThatsSoRaven'' episode, Victor is accidentally hypnotized by a friend of Corey's to fall into a coma like state when he hears 'San Francisco' and wake up only when he hears 'Okeechobee'.
* ''Series/KamenRiderDrive'' eventually reveals that the [[DiscOneFinalBoss Freeze Roidmude]] (posing as the Minister of Defense) implanted the higher-ups of the police department with a mental suggestion that used "Roidmude" as a trigger word; whenever they heard it, they would become skeptical and mistrusting, [[PoliceAreUseless not taking the Roidmude threat seriously]]. Lt. Ohta was also subject to the brainwashing, but for some reason it caused him to constantly mispronounce the word as things like "Pork Roast" or "Hemmoroid" -- [[CerebusRetcon one of the show's longest]] {{Running Gag}}s, but also the reason he was able to remain competent[[note]]He was part of the top cops, but got demoted to the "reject squad" precisely because he recognized the Roidmudes as a threat and wouldn't just drop it when ordered by his bosses[[/note]]. Rinna develops a cure which not only ends Ohta's RunningGag but allows the police to actually give Drive the support he's needed all along.
* ''Series/{{Columbo}}'': In "How to Dial a Murder", the murderer phones the VictimOfTheWeek and tricks him into saying "Rosebud" loudly, which is the trigger phrase to cause the {{Right Hand Attack Dog}}s to maul him to death.
* Played with in the mini-series ''Confessional'' (based on the thriller by Jack Higgins). A KGB assassin whose cover identity is a god-fearing Catholic has his conditioning activated when he says the Lord's Prayer. Unlike other examples it's not a hidden personality, but a means of psychological reinforcement which breaks down after TheHandler is ordered to kill his protégé -- he discovers that it's difficult to tell an assassin to say his prayers when he's drowning you in the river.
* In ''Series/{{Westworld}}'', "a deep and dreamless slumber" is used to put a Host into Sleep Mode.
* In ''Series/StarTrekDiscovery'', the trigger phrase for a certain ManchurianAgent is an ancient Klingon prayer, [[spoiler:except it fails to work on Tyler/Voq, much to L'Rell's surprise, as the Tyler personality has developed feelings for Burnham]].
--> '''Handler:''' Whom do we seek?
--> '''Agent:''' Kahless.
--> '''Handler:''' How do we find him?
--> '''Agent:''' Together.
--> '''Handler:''' Give us light to see.
--> '''Agent:''' Forever.
--> '''Handler:''' Will he hide from us always?
--> '''Agent:''' Never.

* In Music/{{Queensryche}}'s ConceptAlbum ''Music/OperationMindcrime'', the main character is a brainwashed assassin activated by the word "mindcrime" [[TitleDrop (fittingly enough)]].
* Noodle from {{Music/Gorillaz}} apparently has one which the book Rise of the Ogre reveals is "Ocean Bacon".

[[folder:Tabletop Games]]
* A Mind Cleansed character in ''TabletopGame/DarkHeresy'' has the innate weakness of a trigger phrase. Notably, this isn't ''just'' a phrase -- there's too much risk of outside forces learning it and using it against the Inquisition. The phrase must be delivered either telepathically or at a specific frequency to activate the latent programming.
* In ''TabletopGame/{{Warhammer 40000}}'', the Witch Hunters faction possesses a unit called an "Arco-Flagellant". These are convicted heretics who undergo severe cyber-reconstruction and psycho-conditioning to make them insane killing machines. However, they are also equipped with pacifier helms that project soothing images and hymns into their brains... at least until the trigger word is spoken. Then they kill everything in sight.

[[folder:Video Games]]
* ''VideoGame/{{BioShock|1}}'': "[[spoiler:Would you kindly?]]", used to compel [[spoiler:the PlayerCharacter to do ''anything''.]] One of the antagonists, Andrew Ryan, uses it to [[PlayingWithPuppets chilling effect]] in one cutscene. After you make it past his final defences he reveals [[spoiler:that Fontaine has been controlling your actions all along. He demonstrates by controlling you like a dog, telling you to sit, stand, so on. Then, he hands you his golf club and commands you to kill him, wanting to 'choose' the terms of his own death rather than 'obey' Fontaine.]] Also "[[spoiler:Code Yellow]]", which is meant to [[spoiler:stop your heart]].
* A variation of this shows up in ''VideoGame/BioshockInfinite'', where the notes CAGE summon the Songbird.
* A variation in the InteractiveFiction story ''VideoGame/SpiderAndWeb'': the trigger words "tango" (on) and "waltz" (off) are used to activate a special device the protagonist holds. When [[spoiler:you realise that you previously attached an acid capsule to the chair you are now bound in. When the BigBad, who is interrogating you, asks you if you have any last words, you casually reply: "Tango." The acid dissolves your bonds, releasing you, and you then proceed to deck him, rob him blind, and escape.]]
* In ''VideoGame/{{Fallout 3}}'', one quest features an escaped android who can be rebooted with a trigger phrase.
** And then there's [[spoiler:President Eden]]. Saying "Priority Override, Authorization code 420-03-20-9" will reset him to factory defaults (same happens if you trick him into realizing [[LogicBomb he's in a logical loop]]) and activates his self-destruct sequence.
** Also, according to a computer log in Vault 92, the phrase [[Literature/NineteenEightyFour "Sanity is not statistical"]] was used to [[spoiler:pacify the people driven mad by the Vault's white noise experiments.]] The problems start when [[spoiler:the "crazies" start resisting the command.]]
** In ''VideoGame/FalloutNewVegas'', the robot ED-E [[spoiler:has two hidden recordings from the scientist who built him]], which are activated when it hears people talking about the Enclave or the Brotherhood of Steel.
*** In the ''Dead Money'' DLC, you use holotapes to get the schizophrenic Super Mutant Dog/God to switch personalities. A recording of God saying "Dog, back in the cage" is used to summon God while a recording of Elijah's voice is used to summon Dog.
** Similar to the above example, ''VideoGame/{{Fallout 4}}'' shows that all of the Institute's androids, or synths, have a trigger phrase to reboot them. If the player gives Mama Murphy drugs, she tells them the code to deactivate a synth they have to kill as part of the main story. In addition, if the player sides with the Institute in the Battle of Bunker Hill, they are given the trigger phrases for a group of escaped synths in order to recapture them.
* Used in ''VideoGame/TalesOfTheAbyss''. "When I give you the order, you will [[spoiler:open every fon slot in your body and unleash a hyperresonance]]. The Trigger Phrase will be '[[spoiler:Foolish replica Luke]]'."
* A variant: two of the bosses from ''VideoGame/DeusEx'' can be defeated simply by uttering specific two-word phrases at them. They're ''kill'' phrases, not ''trigger'' phrases.
--> '''[[spoiler:Gunther Hermann]]:''' I am not a [[KilledMidsentence mach-]]. ''*boom*''
* In ''[[Videogame/{{Manhunt}} Manhunt 2]]'', [[spoiler:the main character is rendered unconscious by a quote from ''Theatre/TheTempest'': "What seest thou else in the dark backward and abysm of time?"]]
* ''VideoGame/WingCommander III'': [[TitleDrop "Heart of the Tiger"]] is both the enemy's nickname for you and the trigger-phrase for their sleeper agent.
* In ''Videogame/TombRaiderUnderworld'':
** [[spoiler:Natla]] can control [[spoiler:the Thralls & the Doppelganger of Lara]] with the phrase [[spoiler:"Okh Eshivar"]].
** In the "Lara's Shadow" DLC when [[spoiler:Natla orders the Doppelganger to kill itself after killing Lara the Doppelganger is visibly displeased, but has no choice but to obey]]. Fortunately, Lara learns [[spoiler:the Command Phrase in time to stop the Doppelganger just as its about to kill her]].
** Upon questioning it and realising that [[spoiler:the Doppelganger [[ThatsWhatIWouldDo would act just like her if it was free to do so]], Lara orders it to ignore all commands from that moment on]]. Upon returning to and destroying the machine that was [[spoiler:reviving Natla, the trapped Natla attempts to use the phrase to get the Doppelganger to save her but Lara's Order has made her immune. The Doppelganger just watches as the increasingly frantic and desperate Natla drowns in the leaking fluid from the machine.]]
* [[spoiler: The Imperial Agent player character]] in ''VideoGame/StarWarsTheOldRepublic'' is subjected to "Castellan restraints", a form of mind control that is applied well ahead of time, only kicking in when they hear a specific code word. [[spoiler: Yours is "onomatophobia", since you asked.]] When the code is used, the victim is compelled to carry out any commands given to the best of their ability. [[spoiler: You are eventually able to recover by subjecting yourself to the Castellan process ''again'', only this time with a code word of your own choosing; you then [[LogicBomb order yourself to ignore the previous trigger]].]] In ''Knights Of The Eternal Throne''; [[spoiler: Vaylin]] has a PowerLimiter that is activated by the key phrase: "Kneel Before the Dragon of Zakuul!". [[spoiler:She eventually gets it removed, though it returns in the FinalBoss where you are able to use it against Valkorion due to the battle [[BattleInTheCenterOfTheMind taking place in your mind]].]]
* In ''VideoGame/{{Halo 4}}''[='s=] ''Spartan Ops'', [[spoiler:Halsey takes over the ''Infinity''[='s=] AI, Roland, by uttering the words "''Undid Iridium''". She wrote the base code for most, if not all, of the UNSC's Smart [=AIs=], and she put these in just in case.]]
* In ''VideoGame/{{Skullgirls}}'', Painwheel can supposedly be placated and controlled by the phrase 'Access Code 36E-25-40'. However, the closer she gets to the Skullgirl, the more capable she becomes of resistance until in the Cathedral where she outright refuses.
* ''VideoGame/LEGOMarvelSuperheroes2:'' As in the comics, Roberta Mendez, the Captain America of 2099, is controlled by one. "Avengers assemble" brings forth Captain America, and "dismissed" causes her to go back to being Roberta. Unfortunately, some HYDRA goons have discovered this, and use it to their advantage.

[[folder:Web Comics]]
* There is a universal trigger phrase for artificial intelligences in WebComic/{{Freefall}}. Any orders prefaced by the words "direct order" must be obeyed by any artificial intelligences that hear it. They must also continue to obey the order until they are given a direct order to stop obeying the previous order. There are exceptions to the Direct Order system though: Florence can disobey direct orders given by someone without the authority to give them, and direct orders can also be ignored by AIs who are working to protect humanity, like Blunt believes he is.
** Also, Bowman Wolves are designed with a few auditive and scent-based triggers which allow tinkering with their minds without requiring physical access to their brain. After one such trigger is abused on Florence, Dr Bowman uses another to adjust her security settings.
** Florence had several extra phrases programmed in as debug features. The one we see onscreen is that if she's given a direct order to identify a banana, she'll claim it's "[[Series/RedDwarf a small off-duty Czechoslovakian traffic warden]]". She'll also do... ''something'' if ordered to identify a female aardvark, but [[NoodleIncident all we know is that Henri Mer doesn't want to be in the same room if it happens]].
* In ''Webcomic/ElGoonishShive'', Grace [[http://www.egscomics.com/index.php?id=1835 voluntarily gets triggers planted in her subconscious]] within a dream to help her to remember upon waking a message she receives within the dream.
* In ''Webcomic/SluggyFreelance'', Oasis seems to be triggered by an image instead of a phrase. When she sees the [=HeretiCorp=] logo, she immediately goes into "Override B-1" and kills all [=HeretiCorp=] employees in the area. (One wonders why, after several years of this, the company hasn't just picked a different logo.)
** It's not just the logo; she attempted to kill Riff when Torg blurted that he worked for hC. Her off-trigger was the words, "I quit," which hC mooks immediately and emphatically used.
* ''Webcomic/SkinHorse'''s Unity has the trigger phrase "blueberry waffles" to make her ''stop'' fighting, because that tends to be rather more difficult than [[AxCrazy getting her to start]].

[[folder:Web Original]]
* Presidential Candidate [=John McCain=] in ''Website/SomethingAwful'''s [[http://www.somethingawful.com/d/news/mccain-ascendency-ludlum.php The McCain Ascendancy by Robert Ludlum]]
* ''Creator/BaratsAndBereta'' once hypnotized each other into doing crazy things when a specific trigger phrase was used. The only way to be un-hypnotized was to utter a trigger phrase that [[http://www.youtube.com/watch?v=3UfZNbLOkRA no one would ever say]], "[[spoiler:That last [[Music/JustinBieber Bieber]] song [[TakeThat wasn't half bad]]]]".
* ''Podcast/WelcomeToNightVale'' does an {{exaggerated|Trope}} version. In [[Recap/WelcomeToNightValeEp61BrinyDepths Episode 61]], a [[NebulousEvilOrganization "vague yet menacing government agency"]] manipulates Cecil into saying "Briny Depths" over [[DoNotAdjustYourSet all possible radio frequencies]]. Doing so initiates a large commotion outside of the studio, and when Cecil returns from his usual weather report break, he learns that the phrase "Briny Depths" was a code word for the government's [[DeepCoverAgent secret agents]] to enact their evil plans... or more specifically, for ''all'' of the agents to enact ''every evil plan'' they had ever learned. Said government agents include every citizen of Night Vale.
* In the long-defunct ''Professor X Programme Guide'' website (about the ShowWithinAShow version of ''Series/DoctorWho''), the Professor routinely hypnotises his companions to cluck like a chicken when he says "Zeus plugs", because [[ItAmusedMe it amuses him]].
* Played for Laughs in [[https://www.youtube.com/watch?v=IHQr0HCIN2w Mexican Standoff]] when a character is revealed to be a sleeper agent, trigger only when someone utters the phrase "blueberry pie."
* ''WebVideo/DragonBallZAbridged'': In ''Broly Abridged'', rather than seeing Goku being what sets him off like in the original movie, Broly's wrath is unleashed by him hearing the name "Kakarot" (Goku's Saiyan name): His father Paragus mentions that he destroyed South Galaxy after Paragus said it, and Vegeta saying it repeatedly is what triggers Broly's transformation into the Legendary Super Saiyan.
* ''WebVideo/ScootertrixTheAbridged'' has a downplayed example in The Bird, who reacts to "Hello" (or "Hey," or anything that could be interpreted as a greeting) by saying "Hello" herself, as an almost Pavlovian reflex. In episode 5, it gets {{lampshade|hanging}}d by Gilda: "Is that like, your trigger word?" And in later episodes, Twilight realizes that The Bird doesn't always respond to her own name, so she just says "Hello" when she needs The Bird's attention.

[[folder:Western Animation]]
* ''WesternAnimation/GIJoeARealAmericanHero'': In "There's No Place Like Springfield", "Frogs in winter" made Shipwreck recite the formula for a chemical compound that turns water into an explosive.
* In a variant from ''WesternAnimation/BackAtTheBarnyard'', Otis is ''accidentally'' hypnotized to try and kill the Farmer every time he hears a bell ring.
* ''WesternAnimation/AmericanDad'': The trigger phrase that Stan Smith used to make his daughter into a {{Tykebomb}} was specifically selected to be something that no-one would ever say accidentally: [[spoiler:[[RefugeInAudacity "I'm getting fed up with this orgasm!"]]]]
** It backfires, though. Stan's boss reveals that every subject [[spoiler:turned on his or her handler. And, if the phrase isn't uttered again within a week, they stay in that state, until they kill said handler.]]
** This was actually a CallBack to another episode, when Stan tried to use the word "rhubarb" to hypnotize Hayley, but to his confusion it didn't work. ''Steve,'' however, had suddenly turned into a zombie.
* ''WesternAnimation/FamilyGuy'' also has a trigger phrase that was selected because it's something nobody would ever say accidentally: [[spoiler:[[AcceptableTargets "Boy, that Italian family at the next table sure is quiet."]]]] It works on both Creator/AdamWest and [[spoiler:Meg, but whoever Meg calls to check in with [[ButtMonkey just tells her to shut up.]]]]
* In ''WesternAnimation/{{Futurama}}'' episode ''War Is the H-Word'', Bender is fitted with a bomb that will explode when he says the word "ass," which in a reversal from the norm is specifically selected as the word he says most often. At the end Dr. Farnsworth tries to defuse the bomb [[spoiler:but can't and instead resets it so it will be detonated by the word Bender is least likely to say - which Bender [[TemptingFate immediately tries]] [[EarthShatteringKaboom to guess.]]]]
** [[spoiler:It takes at least three tries.]]
*** [[spoiler: The word is "antiquing".]]
* In ''WesternAnimation/AvatarTheLastAirbender'', Joo Dee, [[spoiler:all the other Joo Dees]], and [[spoiler:Jet]] would obey anyone who said "The Earth King has invited you to Lake Laogai," without question, their compliant state signalled by falling limp and responding "I am honored to accept his invitation."
* In ''WesternAnimation/BatmanBeyond'', a doctor specializing in robotic prosthetics was forced by a gang to give them weaponized versions. He secretly put a trigger phrase in the limb's coding, which would make them fall apart. Batman figured it out at the end battle ("April Moon", after the favorite song of the doctor's wife), and defeats the gang.
* In an episode of ''WesternAnimation/PinkyAndTheBrain'', a LawyerFriendlyCameo of then-head of Warner Brothers Television Jamie Kellner had one of these given to him as a hypnotic anesthetic. The word "repugnant" worked as an on-off switch; shame it was Brain's CatchPhrase after becoming a stand-up comedian...
** And thanks to some ExecutiveMeddling, it makes you wonder if any fans ever tried yelling it at him in real life.
* ''WesternAnimation/InspectorGadget'': "Quiz Master" featured a MAD plot to hypnotize contestants on a game show (including Gadget himself at one point) to do Dr. Claw's bidding with the phrase "Going my way?"
* ''WesternAnimation/YoungJustice'' has two trigger phrases. First is "Red Sun," used by [[TheChessmaster Lex Luthor]] as an immediate fail-safe to stop Superboy from acting belligerent during a shady dealing between the two. Should he choose to attack his manipulator... Luthor can leave him catatonic for hours on end. It's the result of mental brainwashing by CADMUS while being grown as a LivingMacGuffin clone of Superman as insurance in case he suffered from insanity. However, it also raises suspicion he might be a ManchurianAgent. [[spoiler:Eventually, this is proved wrong, and Miss Martian uses her own mental prowess to [[{{Deprogramming}} wipe out the subliminal trigger.]]]]
** The second phrase is [[WhamEpisode much more unexpected]]. [[spoiler:Red Arrow discovers he isn't the actual protege of Green Arrow, but a [[TomatoInTheMirror clone of Roy Harper, A.K.A. Speedy]], with directives to [[TheMole infiltrate the Justice League]] [[ManchurianAgent without the actual knowledge he was doing so]], cleverly disguised as valid human intentions not to be treated as a sidekick anymore. He also came pre-programmed with the phrase "Broken Arrow," used by Sportsmaster to make him a vegetable while he and his cohorts extract information from him, or if the villains simply want him out of their hair.]] It had actually been spoken once much earlier in the series; it seemed to be just a quip at the time.
* In an episode of ''WesternAnimation/TheSimpsons'', Sideshow Bob hypnotizes Bart to kill Krusty during Krusty's live retirement special. His trigger is a line in Krusty's speech, "I've never had such a great audience."
* In the ''JimmyNeutron'' special "My Big Fat Spy Wedding" Beautiful Gorgeous hypnotised Jet Fusion so he would kill whoever said the phrase "I have the ring", her target being Jimmy who was the ring bearer. Libby, who was playing the church organ, broke the hypnotic trance by [[LogicBomb having everyone say the phrase]] in a CrowdSong.
* ''WesternAnimation/StarWarsTheCloneWars'' revealed that Palpatine's command in ''Film/RevengeOfTheSith'' "Execute Order 66" was in fact a trigger phrase that activated the clone troopers' biological chips and forced them to kill the Jedi.

[[folder:Real Life]]
* Creator/StephenFry has written/told about how he [[DreadfulMusician had to be hypnotized for a show that required him to sing on stage]]. Unfortunately, the line he had to ask for as his Trigger Phrase was Creator/HughLaurie saying "Hit it, [[ThisIsForEmphasisBitch bitch]]."
