* AlternativeCharacterInterpretation: The song "When the Day Met the Night" features two characters, the sun and the moon, one being described as explicitly female and the other as explicitly male. But the lyrics are written ambiguously enough that people have interpreted the moon as male and the sun as female as well as the moon as female and the sun as male.
* AuthorAppeal:
** Fans have joked about the "Goddamn doors" being one for the band, as they have been mentioned in both "I Write Sins Not Tragedies" and "Miss Jackson" with similar phrasing.
** Sexual references also come up pretty often (especially in songs written by Brendon)
* AwesomeMusic: At least one song on every album.
** On their cover of "Skid Row" from ''LittleShopOfHorrors, Brendon does one hell of a job [[https://www.youtube.com/watch?v=S-33B84fsKE doing the opening]], which is typically belted out torch singer-style.
* BrokenBase: What happened when the Beatles-esque ''Pretty.Odd.'' came out, with many fans wanting the pop-punk/dance style of ''A Fever You Can't Sweat'' back, and dropped the '!' from the name. And then again, when they bought back the '!' and Ryan and Jon left to form their own band, The Young Veins.
** Also, when they saw the brand new dynamics between the replacement members, Ian Crawford and Dallon Weekes.
** Mention of any of the member's wives/girlfriends can evoke anything from adoration to vitriolic hatred. This is probably caused by fans' DryDocking and DieForOurShip. Mentions of Brendon's wife, Sara, are most susceptible to this, as Brendon is the band's most notable example of EstrogenBrigadeBait. (fortunately the Sara hate has decreased over time) The only other 'official' member with a significant other is Dallon Weekes, who is focused upon much less and has been HappilyMarried to his wife for several years.
* ChivalrousPervert: This is a big part of Brendon's stage persona (and a good part of his personality in RealLife) He's known for rampant [[DoubleEntendre DoubleEntendres]] onstage, pretending to [[FauxYay perform lewd acts on his fellow band members]], posted a Vine where he (jokingly) asked girls to send him pictures of their boobs, has admitted to being a not so EthicalSlut in the past and overall being a LovableSexManiac. He is now HappilyMarried, has written several songs about his wife (including the CrowningMomentOfHeartWarming "The End of All Things) and they are quite cute together.
* CrowningMomentOfFunny: A lot of the things Brendon says on stage can qualify as this, but one example is when Brendon was performing with a bad cold and said something along the lines of "This might be a paradox, guys, but I think God is punishing me for being an atheist."
* CrowningMomentOfHeartwarming: "The End of All Things," which was written as Brendon's wedding vows to his wife, Sarah.
** "Always" is also quite cute as well
* CrossesTheLineTwice: Some of the things Brendon says onstage indulge in this from time to time.
** A story about his mother at a few shows started with "It's not just because [my mother is] incredibly smart and [[ParentalIncest incredibly sexy.]] I can say that because I will never date her." And ended with him saying that he told her: "I am just so fucking glad I came out of YOUR vagina."
** One of their tour videos featured a the band traveling in car and happening upon a Christian music station playing a song that featured the line "Christ is behind me." Brendon noticed the AccidentalInnuendo and started shouting [[FreudWasRight "Christ inside me! Christ, get deep inside me! Put your love inside me! SHOVE IT all up inside me!]] It got to the point that even Dallon, the band's TokenReligiousTeamMate [[ActuallyPrettyFunny couldn't help but crack up.]]
* EarWorm: At least one song on every album can qualify as this.
** A lot of the 6 second songs Brendon posts on his Vine qualify as well
* EnsembleDarkhorse: Dallon for a lot of people, the fact he had [[TheBrobecks a discography]] before he entered the band helped.
* FaceOfTheBand: People usually think of Brendon, the lead singer, before Ryan Ross, the main songwriter during the ''A Fever You Can't Sweat Out'' and ''Pretty. Odd.'' eras.
** Justified as he's the only member who has remained with the band since the beginning
* FauxSymbolism: In concert, "This is Gospel" has been performed in front of screens displaying stained glass windows, very much like ones you would see in a church. [[RuleOfCool Although this looks pretty cool,]] it's not very fitting. The song was not written to contain any religious themes and even if you examined the lyrics, they do not reference religion. The fact that Brendon is a devout atheist makes this even more baffling.
** [[http://www.youtube.com/watch?v=2uYGjSaasJ4 An advertisement for the band's "This is Gospel Tour"]] features Brendon Urie playing a televangelist WaxingLyrical to the lyrics of the song. This is played for laughs and was probably intended to be ironic anyway.
* FridgeBrilliance: One can notice that Brendon is wearing his wedding ring during the music video for 'Nicotine,' which was probably an accident, as the character is supposed to be bringing flowers to his lover (which could unintentionally imply YourCheatingHeart) But when his lover is revealed [[spoiler: to have been DeadAllAlong, one could interpret that she was his wife and he still wears his wedding ring]]
* FriendlyFandoms: FallOutBoy and Panic! fans often overlap. This isn't surprising considering their similar music styles, shared origins and penchant for [[LongTitle Long Titles]].They overlap a lot with the Music/MyChemicalRomance fanbase, too. This is probably due to the witty and intelligent rebellion lyrics. It's more like, which one did you become a fan of first.
* FunnyAneurysmMoment: Their NewSoundAlbum (Pretty.Odd.) begins with a track that assures the listener that they are "still the same band." After the release of the album, half of the band left and even later, after Spencer's departure, Brendon was the only remaining original member.
** [[http://www.youtube.com/watch?v=8hQ6QjeKUOs A video]] that was made as a teaser for the album Vices and Virtues has a focus on 'letting go of 'baggage' so you can move on and become a better person.' By the end of the video, Brendon and Spencer are the only ones left and willing to 'move on' and then this exchange happens
-->'''Brendon:''' ...It's just us...
-->'''Spencer:''' It always has been
** At the time, it was simply an odd video full of MindScrew and FauxSymbolism. After the release of the album, however, Spencer came out about his substance abuse problems and stopped touring with the band. This could make the video a bit of a TearJerker if it wasn't already.
* GrowingTheBeard: Brendon took leaps and bounds lyrically between "Vices&Virtues" and "Too Weird To Live". It's a noticeable difference if you read the lyrics right after one another. The topics get more mature too.
* HeReallyCanAct: Brendon pulled this off in his role in RaziasShadow, which is an actual story-driven musical rather than a standard album.
* HilariousInHindsight: Many people have noted that [[http://images2.fanpop.com/images/photos/4200000/i-write-sins-not-tragedies-panic-at-the-disco-4240217-320-240.jpg the groom]] in the music video "I Write Sins Not Tragedies" bears a remarkable resemblance to bassist [[http://25.media.tumblr.com/tumblr_lfhh54agLm1qgyl0ko1_500.jpg Dallon Weekes]], who didn't join until years later
** In the early years of the band, an interviewer had Brendon and Ryan do a 'Mad Libs' type game, which resulted in a very silly love letter that began with the "My nasty love..." Brendon and Ryan joked that they would make a song out of it. Several years later, the biggest hit of Too Weird to Live, Too Rare to Die was the song "Miss Jackson" which features the line "...are you nasty?" repeatedly in the chorus.
* InJoke: There are a lot of jokes about milk in the fandom. [[BrainBleach Don't]] [[ConvenientlyCommonKink ask]]. [[note]]If you really want an explanation, (warning, next sentence contains major Squick) it's a reference to the infamous fan fiction that features Brendon giving Ryan a milk enema[[/note]] It became so popular that even Brendon had heard of it and addressed it in an Instagram video.
* MemeticMutation: On the YouTube page for ''The Ballad Of Mona Lisa'', a frequent comment is about the netgun used to capture Mary at the end.
** Closing the goddamn door.
** A post circulating around the internet joking that the song "I Constantly Thank God for Esteban" actually referred to the character from TheSuiteLifeOfZackAndCody has been popular as well
** [[http://stumpxvx.tumblr.com/post/80542090354/dont-u-hate-it-when-its-nine-in-the-afternoon-but A post on tumblr featuring the statement "dont u hate it when its nine in the afternoon but ur eyes are just normal sized"]] (a reference to the lyrics of the song "Nine in the Afternoon" led to numerous non-fans of the band becoming extremely confused and desperate to find out what the post actually meant. Hundreds of thousands of notes later, some people still don't understand what the post means.
** The song 'Northern Downpour' is so notorious for its TearJerker qualities that one just needs to type "brendon urie c" into the youtube search bar to have " brendon urie crying during northern downpour" be one of the recommended searches. The song has also been jokingly referred to as "Northern Frownpour" by fans.
** Jokes about Brendon secretly wanting Ryan to come back are also popular
* {{Narm}}: Among other things, many of their outfits during the ''A Fever You Can't Sweat Out'' era.
** The Girls/Girls/Boys music video, if it isn't FetishFuel.
* NarmCharm: They are know for their signature campy style.
* NightmareFuel: The videos for "Miss Jackson" and "This is Gospel"
* PoorMansSubstitute: Inverted. No one really gives much thought anymore to original bassist Brent Wilson (Probably because Jon Walker was around longer and much more willing to smile in photo shoots)
** It seems like Dallon Weekes and Ian Crawford are about to become this, after Ross' and Walker's departure. Though many fans adore them, many are still quite bitter over the split.
* PortmanteauCoupleName: Rydon/Ryden (Ryan/Brendon), still very popular despite the split. Joncer (Jon/Spencer), usually a case of PairTheSpares. After the split, Brencer (Brendon/Spencer) was formed.
** Now introducing Brallon (Brendon/Dallon)(amusingly, people have mentioned this ship name could refer to the pair of Dallon and his wife as well, as her name is Breezy)
* RealLifeSubtext: Post-split, Brendon would get [[ManlyTears notably emotional]] while performing 'Northern Downpour.' It's a probable reason for why the band doesn't perform it live anymore.
* RealPersonFic: [[http://community.livejournal.com/slashatthedisco/ And how!]]
* ShipToShipCombat: Ryden or Brallon? Be careful, if you take a side.
** Even before Brallon, pre-Split, once ''Live In Chicago'' came out, Brencer (Brendon/Spencer) and Ryden had some pretty nasty fights on livejournal.
* SignatureSong: ''I Write Sins Not Tragedies,'' to the extent that performances often involve [[AudienceParticipation Brendon and/or Dallon pointing the mic at the audience as they sing a majority of the song]]
* StartOfDarkness: Whether you buy into the Ryan Ross hatedom or not, it's clear that the content of ''Pretty. Odd.'' is a precursor to his leaving the band with Jon Walker and creating The Young Veins, whose music that sounds very much like ''Pretty. Odd.''.
* SurprisinglyImprovedSequel: While ''Pretty. Odd.'' was not this for ''A Fever You Can't Sweat Out'', for most people, and ''Vices & Virtues'' also fell flat, ''Too Weird To Live, Too Rare To Die!'' was extremely well done, even attracting people who were ambivalent about the first three albums.
* TearJerker: Post-Split, a lot of ''Pretty. Odd.'' songs have become this for people. ''Folkin' Around'' especially.
** "Northern Downpour," [[ManlyTears apparently]] [[http://www.youtube.com/watch?v=4Zg9VDtwC7k even for Brendon]]
** ''Trade Mistakes'', especially the chorus of the song.
** [[http://www.panicatthedisco.com/post/57634899440/hi-im-brendon-urie-from-panic-at-the-disco Brendon's post on the website about Spencer's addiction and departure]] is quite sad as well.
* TheyChangedItNowItSucks
** What some fans thought when ''Pretty.Odd.'' came out.
** Also when the band removed the exclamation mark after "Panic" in the name. The exclamation mark has since returned.
* TheyCopiedItSoItSucks: The band got a lot of heat for their blatant similarities to FallOutBoy. The fact that they were huge fans before they were even a band and got signed by Pete Wentz is a good explanation of this.
