A Secret Word is frequently used in popular culture to provide tension and excitement. A minority of people know it, others don't and everyone is curious whether those who don't know it will find out what it is, or, how long it will take them? In certain stories the secret word may be a TriggerPhrase: once it's said a magic spell or hypnotic mind control device may change everything. In other stories a guard may only let someone enter a room if the visitor says the secret word. See also ThePasswordIsAlwaysSwordfish, HighlyVisiblePassword (for tropes about obvious secret words) and JoeSentMe (when a secret word has the variation ''"X sent me"''.)

In certain TV shows the audience is informed beforehand what the secret word for today is, while the panel members or contestants are unaware. During the show they have to guess it or, even more fun, are tricked into saying it. When the secret word is finally revealed to everybody the audience will laugh and cheer in excitement. He/She who said the secret word may win a prize or is considered to be the ButtMonkey for that episode.

Secret words are also sometimes used during stage performances, as a sort of InsideJoke that either only the fans can get (and thus feel united by) or something that they can try to decipher as the show goes on.

Not to be confused with TrustPassword.

!!Examples:

[[foldercontrol]]

[[folder:Radio]]
* The Dutch radio show ''"Ekstra Weekend" (2006-2013)'' had an item called "The Secret Word", in which listeners could send their text messages at the moment the secret word-jingle was played. When a listener was chosen, he or she would receive the secret word off-air. Then a friend or relative of the listener is called. When they pick up the phone, the contestant has to describe the secret word, without actually saying it or mentioning they are on national radio. When the other person guesses the word, instantly the James Last version of the "Too Fat Polka (She's too fat for me)" is played, while the entire studio goes crazy. Hammering things with trashcan lids or forming a conga line to celebrate the correct answer. At last the prizes the contestant wins are revealed. When the provided relatives or friends can't be reached, Fabienne de Vries was called. She's usually helpful to the contestant and almost always gets the right word.

[[folder:Film]]
* ''Film/HorseFeathers'': In this Creator/MarxBrothers film an entire comedic scene is built around people unable to enter a room unless the [[ThePassWordIsAlwaysSwordfish say the password, which Groucho and Chico unknowingly keep saying]].
* In ''Film/TheBookOfHenry'', a gun-store owner skirts or breaks the law for those who name-drop Dominic.

[[folder:Live-Action TV]]
* ''Series/{{Password}}'': In this game show contestants had to guess a secret word through a series of clues.
* ''Series/KeepTalking'': Had the same format as ''Password''.
* ''Series/YouBetYourLife'': Some show tension revolved around whether a contestant would say the secret word, a common word revealed to the audience at the show's outset. If a contestant said the word, a toy duck resembling [[Creator/MarxBrothers Groucho Marx]] with a mustache and eyeglasses, and with a cigar in its bill, descended from the ceiling to bring a $100 bill. Groucho sometimes slyly directed conversation to encourage the secret word to come up.
* ''Series/PeeweesPlayhouse'': At the start of every show Pee-Wee informed the audience, "The secret word for today is _____." He would try to make his guests say it, but they were not always that easily fooled and so sometimes Pee-Wee accidentally said it himself. When the secret word was said all children were allowed to scream real loud while in Pee-Wee's house itself an alarm went off.
* ''Series/SaturdayNightLive'': A recurring joke in the show was the segment "Secret Word" in which two contestants in a game show had to guess hidden words based on clues from their celebrity partners.

* Creator/EllenDeGeneres had a "Mystery Word" on her talk show, which she tried to get her guests to say. If one of them said it, it meant either a prize for the audience or a charity donation.
* In the episode of ''Series/SesameStreet'' where the adults finally [[NotSoImaginaryFriend see Mr. Snuffleupagus]], Big Bird arranges for them to come over whenever he shouts a secret word, "food". At one point, the cast debates over whether "food" is a silly word to Phil Donahue.
* ''The Kenny Everett Video Cassette'' had a segment whose sole purpose was to have a celebrity guest CoveredInGunge. They could allegedly avoid this by saying the 'secret word', which was always something incredibly unlikely to come up in casual conversation, like 'theodolite'.
* The first version of the game show ''Series/NowYouSeeIt'' introduced an element where a team could score 10 bonus points if his/her partner found the answer to a question that the other team member had written down beforehand.

[[folder:Music]]
* Music/FrankZappa introduced a "secret word" to his audience during all of his concerts.

It's specifically mentioned during ''Music/FillmoreEastJune1971'' and ''Music/TheYellowShark''.

[[folder:Mythology and Religion]]

--> And the Gileadites took the passages of Jordan before the Ephraimites: and it was so, that when those Ephraimites which were escaped said, Let me go over; that the men of Gilead said unto him, Art thou an Ephraimite? If he said, Nay; Then said they unto him, Say now Shibboleth: and he said Sibboleth: for he could not frame to pronounce it right. Then they took him, and slew him at the passages of Jordan: and there fell at that time of the Ephraimites forty and two thousand.

-->'''Vicky''': HELP!
-->'''Grocho!Cosmo''': Sorry. The secret word was "pie".
--> (pies her in the face)
* ''WesternAnimation/FamilyGuy'': The episode "Peter Griffin: Husband, Father... Brother?" has a parody of ''Series/PeeWeesPlayhouse'' in which Peter turns his house into Pee-Wee Herman's playhouse. After Lois calls this "ridiculous" it turns out that was the secret word for today.
