Idiotic Partner Confession is a situation in which X is keeping something from Y, be it a something he's done, something he's planning, or just something he said earlier that he ''really'' doesn't want to tell Y. The problem is, Z is also aware of this secret, and just happens to be a [[TooDumbToLive complete idiot]]. So what does Z do? He starts talking about it right in front of Y, if not directly to him, of course! This will undoubtedly lead to X [[BeQuietNudge trying as discreetly as possible to get Z to shut up]], with Z [[WhatAnIdiot completely oblivious that he's saying anything remotely wrong]]. This will likely [[DoNotTauntCthulhu piss Y right off]], and lead to all sorts of trouble for poor X.

Y can be a [[BigBad villain]], [[TheParentTrope some sort of parental figure,]] or anyone else who X would have any reason not to be honest with. Z doesn't necessarily have to be an idiot to do this--just somewhat unaware of X's nervousness. Or it could very well be a case of WillNotTellALie.

Different from RightBehindMe, although the tropes might overlap. Compare AccidentalPublicConfession.

* ''Disney/TheLionKing'':
** Simba when he questions why Zazu is acting so afraid of the hyenas when he said earlier that they were "slobbery, mangy, stupid poachers". Said hyenas are, of course, right in front of them. Not completely played straight, since Simba isn't so much an idiot as an innocent child, and Zazu teaching him to be [[FantasticRacism racist]] is a bad idea in [[IdiotBall multiple]] [[TookALevelInJerkass ways.]]
** A second example later on, when Mufasa corners the three Hyenas after they tried to kill Simba. Shenzi and Banzai immediately insist that they had no idea Simba is Mufasa's son; then Ed spills the beans.

* At the beginning of ''Film/HocusPocus'', the Sanderson sisters are trying to convince the angry mob that they are not witches:
-->'''Winnie:''' Don't get your knickers in a twist! We're just three kindly old spinster ladies.\\
'''Mary:''' Spending a quiet evening at home.\\
'''Sarah:''' Sucking the ''lives'' out of little children!\\
(''Winnie chokes Sarah'')
* In ''Way Out West'', Creator/LaurelAndHardy are tasked with finding the heiress of a gold mine in a Western town. Of course, Ollie would rather keep this a secret as to not attract unsavory types; so what does Stanley do? Reveals the whole thing to a shaddy bartender first thing on their arrival. Ollie naturally [[DopeSlap slaps]] his idiotic partner, but way too late.

* ''Series/OurMissBrooks'' has a non-idiot example in the episode "Blue Goldfish". Unaware that Mr. Conklin had been boasting about his hardiness to the cold, Harriet Conklin reveals her father's spent the entire day sitting on an electric blanket.
%%* [[NoCelebritiesWereHarmed London Tipton]] does this in an episode of ''[[Series/TheSuiteLifeofZackandCody Suite Life on Deck]]''.

* ''WesternAnimation/SpongeBobSquarePants'' does this to poor [[ButtMonkey Squidward]] when they're faced with the Flying Dutchman.
-->'''The Flying Dutchman:''' Who be disturbin' the Flying Dutchman in his own lair???\\
'''[=SpongeBob=]:''' It's Squidward. He wants to complain to you.\\
'''Squidward:''' I-I... No, I... no.\\
'''[=SpongeBob=]:''' [[WhatAnIdiot But what about all that stuff about him having a dirty ship, and being lazy, and all?]]\\
'''Squidward:''' (''laughs nervously'') I never said that...\\
'''The Flying Dutchman:''' Insulting a man's ship is worse than insulting his mother!\\
'''[=SpongeBob=]:''' No wait, maybe it was his mother you said was dirty...
* Sort of an example in ''WesternAnimation/AvatarTheLastAirbender'', when Aang and Zuko finally meet the firebending masters, who turn out to be the last living dragons.
-->'''Aang:''' Still think we can take them?\\
'''Zuko:''' Ssh! I never said that!
* An episode of ''WesternAnimation/CodenameKidsNextDoor'' Has Sector V trick Count Spankulot into attacking the people and getting incarcerated for it.
