Trigger Phrase

"Hayley: "It's my life! You can't control me!" Stan: "Yes, I could. I could control you completely. Just by saying a secret combination of words, that no one in the world would ever utter.""

- American Dad

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 Speculative Fiction. The phrase can activate a Deep-Cover Agent or Manchurian Agent, so hidden that the person may not even know they are an agent. The phrase can practically be anything, even a piece of music. It's like a Brown Note 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 Berserk Button that not even the characters themselves know about, used when situations are about to get dangerous. Sometimes, it will help them remember something.

Is everything alright, 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...

Anime and Manga

 * Agents of the Schwarz organization from Mai-Otome are triggered when they receive a letter in a black envelope.
 * uses one to deactivate Melfina in Outlaw Star.
 * to be specific, he uses "It was you who broke my Mason plate." for the above, and "Breakfast is signaled with a silver spoon." to undo it.
 * Ironically inverted in Gunsmith Cats. Mafia boss 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 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
 * One example forms the basis of the plot of Suehirogari's 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 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 tag where "it" has to stay naked. Until they do pass it on, their bodies won't let them even touch clothing despite themselves. Of course, this also means that the victim they kiss has to stay naked next...
 * Done in chilling fashion in Noir, in which Chloe deploys Kirika's "True Noir" personality by saying "receive the final guidance" - and then shooting her.
 * Mahou Sensei Negima doesn't actually have this occur (yet), but when the cast are dealing with a Manchurian Agent in their midst, the team mercenary notes that they can't rule out the possibility of a Trigger Phrase.
 * The Extended soldiers in Gundam Seed Destiny 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 The Password Is Always Swordfish, since the Alliance chose stupidly common words - "" for Stella and "" for Auel (we never learn what Sting's is).
 * An important part of the plot in Last Exile concerns the hunt for four of these, along with the girl they trigger.
 * In Code Geass, 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.

Comic Books
"Emma Frost: "And every time you hear the words 'parsley', 'intractable' or 'longitude' you will vomit uncontrollably for 48 hours.""
 * "Croatoa" from One Hundred Bullets.
 * "Kimota" functions as this in the first issue of Miracleman, instantly restoring the hero's memories when he says it.
 * In Justice League International, the despotic ruler of Bialya, the Queen Bee, triggers Blue Beetle with the phrase "Bialya, my Bialya." Once the heroes have figured out what the hell is going on, it's not very difficult to determine the responsible party.
 * 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 Secret Invasion and the Twisted Toyfare Theatre parody of same. "He loves you." "Who, Northstar? I know, it's just-HEY!"
 * Batman set up an alternate "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
 * In the Dethklok vs. The Goon 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 The Goon. Hilarity (and murder) ensues.
 * Semi-Reformed X-Men character Emma Frost used her powers to shut down two armed guard's pain centers after a fight with Wolverine, which seems like a nice thing to do, but then she stuck something extra in:


 * Ultimate Spider-Man's Norman Osborn set up "Cellar Door" as an all-purpose trigger phrase for his son Harry.
 * The Authority: the military-industrial complex who built Seth, the hillbilly cyborg killing machine with over 1,000 super powers naturally set up a kill switch phrase. They also made sure it was something no one would ever say:
 * In Liberty Meadows, Brandy demonstrates a trigger on Leslie. With a snap of her fingers, he puts the rehab-breaking Dean in a headlock. "SLEEPER HOLD! DAAAAAH!"
 * During the Teen Titans/Outsiders crossover "The Insiders", Superboy was brainwashed by Lex Luthor, who used the words "Vincere Aut Mori" ("Conquer or die" in Latin).

Fan Works

 * In Kyon: Big Damn Hero, Haruhi gives Kyon one of these.

Film
""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.""
 * Serenity: River is activated by a subliminal message in a Fruity Oaty Bar commercial, but is by Simon saying "Eta kuram na smekh," Russian for "That's for chickens to laugh at" (i.e. "That's ridiculous.")
 * The original version of The Manchurian Candidate has both a Trigger Phrase ("Why don't you pass the time by playing a little solitaire?") and a Trigger Card: the Red Queen.
 * In the remake the agents get personalised triggers: And later...
 * The Lathe of Heaven. George Orr is hypnotized so his "effective" (reality changing) dreams can be controlled. The Trigger Phrase is "Antwerp."
 * 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, and I have promises to keep and miles to go before I sleep. Did you hear me butterfly? 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 The Naked Gun movie (where the beeping of a watch was the trigger) when Vincent Ludwig's maid tries to shoot Pahpshmir with an empty gun.
 * (Probably) homaged in Grindhouse


 * "Now is the time for all good men to come to the aid of their Party" was used in one movie I saw as a kid, but I can't remember the name of it.
 * The Ipcress File (1964). "Now listen to me. Shoot the traitor ." 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 Double Agent.
 * In A.I.: Artificial Intelligence, speaking a trigger phrase will cause an android child to permanently and unconditionally love the speaker.
 * Derek Zoolander will kill the Prime Minister of Malaysia when he hears the song Relax.
 * "Constantinople" and "Madagascar" in The Curse of the Jade Scorpion.
 * The toggle for Hawkin's fencing abilities in The Court Jester is a snap of the fingers. Ok, not exactly a phrase, but if music counts...

Literature

 * In 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".
 * "She is gone." Upon hearing that,.
 * In Dirk Gently's Holistic Detective Agency, 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.
 * Sure it is.
 * Dean Koontz 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 False Memory. The villain has different trigger phrases for each person under his control, in the form of haiku. He speaks a line, the subject responds with the second line, then he gives the third line, followed by instructions.
 * Robert Heinlein:
 * Starship Troopers. Mobile Infantry troopers are given a post-hypnotic suggestion to go to sleep upon hearing the Trigger Phrase "Prepare to sleep, one, two, three."
 * Citizen of the Galaxy. 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 Take That to Starship Troopers, The Forever War 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 X Wing Series books is the presence of several brainwashed assassins throughout the 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.
 * 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 inverse Memory Gambit, 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 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 For the Evulz. In the chapter "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. 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 A Series of Unfortunate Events the word "Lucky" is used as a trigger to the point of parody, since the good guys catch onto it and both sides flip back and forth in obeying their commands. The word "Inordinate" deactivates the state.
 * The eleventh book of The Dresden Files, Turn Coat, features one of the antagonists using the Trigger Phrase "The end is nigh." to take control of several.
 * In the YA novel The Adoration of Jenna Fox, Jenna
 * In James Swallow's Warhammer 40,000 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 Honor Harrington 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.
 * In the Emily Rodda novel Rowan and the Keeper of the Crystal, it is revealed in the end that  had been brainwashed by the Zebak years previously, the trigger phrase being the words that
 * In the book The Hot Rock 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 title gem.
 * Used in The Stand, bascially Glen telling Tom "it's time" as in 'time to go West', after hypnotizing him earlier.

Live Action TV

 * One episode of Get Smart, where the agent is Max and the trigger is "Checkmate." Max is meant to challenge his target to a 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 Double Agent in the room shouts "Checkmate!" in delight, and gets shot instead.
 * Dollhouse: Activates: Deactivates:
 * 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.
 * Also often used is "It's going to be ok...", to which the Actives reply "... now that you're here." This gets them to relax and trust their handler.
 * The Odd Couple: "The fault lies not with the stars but with ourselves" made Oscar neat, and a finger-snap made him back to normal.
 * In Big Wolf on Campus, 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.)
 * Nowhere Man. 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 Manchurian Agent killer.
 * Blakes Seven. The location of Star One is revealed by saying the phrase "A fool knows everything and nothing" (the co-ordinates were implanted in the mind of the Charl's Fool).
 * In season seven of Buffy the Vampire Slayer, Spike's trigger is a song his mother used to sing when he was a child.
 * A telepathically delivered Trigger Phrase revealed  as a sleeper assassin in Babylon 5.
 * In the Due South episode "Seeing Is Believing", Fraser hypnotizes most of the other main characters in order to 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 MacGyver, Pete gets brainwashed into shooting whoever utters the trigger phrase "From the bottom of my heart, I salute you". The Big Bad 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). Need I put under a spoiler that MacGyver foiled the plan in the last minute? No, no I don't.
 * In one episode of Beans Baxter, 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 (of course) just happened to match the robot's trigger phrase.

Music

 * In Queensrÿche's Concept Album Operation Mindcrime, the main character is a brainwashed assassin activated by the word "mindcrime" (fittingly enough).
 * Noodle from Gorillaz apparently has one, but it's never been revealed.
 * The book Rise of the Ogre reveals it to be "Ocean Bacon".

Tabletop Games

 * A Mind Cleansed character in Dark Heresy 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 Warhammer 40,000, 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.

 * In Sluggy Freelance, Oasis seems to be triggered by an image instead of a phrase.
