[[caption-width-right:1280:Brendon Urie and Spencer Smith]]

A band created in 2004 by childhood friends Ryan Ross (guitarist/main songwriter), Spencer Smith (drummer), and Brent Wilson (bassist), and later, joined by Brendon Urie (lead singer) and Jon Walker (who replaced Brent in 2006). They were discovered by Music/FallOutBoy's bassist Pete Wentz and signed to his vanity label, Decaydance.

Their name comes from a line in the song "Panic" by Name Taken, but due to the relative obscurity of this reference, the band usually cite "Panic" by Music/TheSmiths, which contains the line "Burn down the disco" in its chorus and is more well known.

They are known for their [[ImpossiblyCoolClothes quirky]] [[RummageSaleReject fashion]] sense, rampant [[FauxYay stage gay antics]], and longer than life song titles. Popular songs include "I Write Sins Not Tragedies", "The Ballad Of Mona Lisa", "This Is Gospel", "But It's Better If You Do", and "Lying Is the Most Fun a Girl Can Have Without Taking Her Clothes Off".

As of July 2009, Ryan Ross and Jon Walker are no longer members and have formed their own band, The Young Veins.

As of 2011, the band has two replacement members, Dallon Weekes (bassist, formerly from Music/TheBrobecks) and Ian Crawford (guitarist, formerly from The Cab). In 2012, Dallon Weekes officially joined the band.

They're often grouped as part of the "Fueled By Five" (five bands from their label, Fueled By Ramen), which also includes FallOutBoy, TheAcademyIs, GymClassHeroes, and CobraStarship.

!!!Tropes applying to the boys

* {{Adorkable}}: Brendon, just so much.
** Also Ryan and Spencer.
*** We must mention Ian and Dallon too.
* AerithAndBob: Current and former members of the band have been named Brendon, Ryan, Spencer, Brent and '''Dallon''' (which actually fits the 'Mormon people give their children odd names' stereotype)
* {{Bishonen}}: Brendon and Ryan.
* BiTheWay/ExperimentedInCollege: [[http://www.pridesource.com/article.html?article=63018 Brendon admitted in an interview to been attracted to guys before and having 'experimented' with guys.]] However he considers himself 'straight' and is married to a woman.
* ButtMonkey: Brent Wilson is this among many fans, who are fond of telling jokes about him working at a [=McDonald's=] now that he's not with the band and/or various sarcastic comments saying they love him and are big fans.
* DudeLooksLikeALady: [[http://i382.photobucket.com/albums/oo265/Blossom_Morphine/brendonstandupstraight.jpg Brendon]], [[http://i213.photobucket.com/albums/cc41/xxindigobubblesxx/hesheorly.jpg Ryan]], and [[http://i213.photobucket.com/albums/cc41/xxindigobubblesxx/2zftpcl.jpg Spencer]] were prime candidates for this trope especially during ''A Fever you Can't Sweat Out'', though this is no longer the case.
* FanNickName: Brendon: Bden and Brenny Bear. Ryan: Ryro and (by his detractors) Ry''ho''. Jon Walker: Jwalk. Ian Crawford: Een.
* FauxYay: The tradition began with Ryan and Brendon and has continued with Brendon and Dallon. Features anything from intentional [[AlmostKiss Almost Kisses]] to simulated blow jobs. Makes up one-third of their act, to the [[YaoiFangirl delight of fans.]]
* {{Four Temperament Ensemble}}. One of the lineups, at least.
** Brendon - Sanguine
** Ryan - Melancholic
** Jon - Phlegmatic
** Spencer - Choleric
* FunctionalAddict: Spencer himself admitted to believing he was this in a recent blog post, where he talked about his drug addiction and getting clean.
* {{Guyliner}}: But of course!
* HeterosexualLifePartners: Ryan and Spencer used to be, arguably.
* {{Keet}}: Brendon might well be the poster boy for this trope.
* MrFanservice: Brendon is a major one, as it isn't at all at common for him to [[WalkingShirtlessScene take his shirt off onstage]], he's almost always involved in any [[FauxYay stage gay]] and it's made abundantly clear by the video for [=Girls/Girls/Boys=], where he spends the ''entire'' video naked. A couple of the other members can also be this to an extent.
* OddCouple: As of now, the two front men of the band are the young (27 as of now) openly atheist, extremely outgoing and LoveableSexManiac Brendon Urie and the older (33), quieter, {{Adorkable}} [[TokenReligiousTeammate practicing Mormon]] Dallon Weekes who has been HappilyMarried since 2006 and has two children
* [[PromotedFanBoy Promoted Fanboys]]: The guys were huge fans of Fall Out Boy, and followed Pete's livejournal before sending him a sample of their music and ultimately getting signed to his label. Brendon has also been featured on FallOutBoy songs multiple times
* RedOniBlueOni: Brendon (red) and Dallon (blue)
* SpellMyNameWithAnS: Panic! At the Disco vs. Panic at the Disco.[[note]]The band omitted the exclamation point during ''Pretty. Odd.'' but it's since returned and it's use is considered the proper way to write the band title.[[/note]]
** It's spelled '''Brendon''', not '''Brandon'''
* StageNames: Ryan changed his name from George Ryan Ross III
* TheTeetotaler: Ryan and Spencer, when the band started. Reason C (Ryan's dad). Kind of HarsherInHindsight in Spencer's case, as of 2013 he went public about his substance abuse problems.
* TheCastShowoff: Dallon Weekes actually designed the cover art for [[http://djjazzyweekes.deviantart.com/art/Panic-Album-Cover-Concept-227170791 Vices and Virtues]] and is a pretty skilled artist. This was a bit subverted though, because it was rarely mentioned.
* TheQuietOne/TheStoic: Dallon onstage
* TokenReligiousTeammate: Dallon is a practicing Mormon, which is a bit of a contrast to atheist Brendon.
* WalkingShirtlessScene: Brendon taking off his shirt at one point is almost happens [[OnceAnEpisode once a concert,]] he's also shirtless in MANY of his Vines. He even posted a [[https://vine.co/v/huH6gnJKDqn vine]] where he sings about not liking to wear shirts (warning: video contains NSFW language)

----
!!Tropes relating to the music and videos

* AcCENTUponTheWrongSylLABle: Listen to "Build God Then We'll Talk", particularly Brendon's pronunciation of "caricature".
* AlbumTitleDrop: "Things are shaping up to be '''pretty odd.'''" (Notable as this is the only time the band has done this)
* AllThereInTheManual: The lyrics that come with ''A Fever You Can't Sweat Out'' expand on some of the songs, for some reason.
--> They ended up... well, making love isn't exactly what I'm looking for. But. You. Get. The. Picture.
** It's part that and part WhatCouldHaveBeen. The lyrics booklet for Fever has all the original lyrics that were written for the songs, not what's actually on the album, which results in things like the above.
* AndNowForSomethingCompletelyDifferent: After an entire album consisting of dance-pop/club/rock, "The End Of All Things" is a heartwarming piano-driven ballad about being in love.
* BalladOfX: "The Ballad of Mona Lisa"
* BiTheWay: This is what Girls/Girls/Boys is about
* BerserkButton: "I Write Sin, Not Tragedies" is about a groom going off on someone insulting his bride.
* BookEnds: ''Vices & Virtues''. Both the opening song "The Ballad of Mona Lisa" and the ending song "Nearly Witches (Ever Since We Met...)" feature the line ''Mona Lisa, pleased to please ya''.
* BreakUpSong: "Lying Is the Most Fun a Girl Can Have Without Taking Her Clothes Off" - ''Then think of what you did/ And how I hope to God he was worth it''
* ChewingTheScenery: After the video for "The Ballad of Mona Lisa" Brendon will be puking up scenery for weeks.
* ClusterFBomb: "Nicotine" features the word 'fuck' at least four times along with the repeated usages of the word 'damn', which is a bit jarring compared to a majority of their other songs.
* ConceptVideo: Nearly all of them. Notable examples are the videos for "[[http://www.youtube.com/watch?v=uBtH2YlNiNc But It's Better If You Do]]" where the boys are musicians in an illegal strip club, and "[[http://www.youtube.com/watch?v=vc6vs-l5dkc I Write Sins Not Tragedies]]", featuring a circus wedding filled with clowns in lingerie!
** "[[http://www.youtube.com/watch?v=gOgpdp3lP8M The Ballad of Mona Lisa]]" is a steampunk funeral scene.
** "[[http://youtu.be/LUc_jXBD9DU Miss Jackson]]" is a [[MindScrew rather surreal and confusing narrative that no one is exactly sure what is is really about]]
** "Nicotine" is about a man bringing flowers to a woman who he is very much in love with [[spoiler: who is revealed to be DeadAllAlong]]
* ConceptAlbum: First album is about various references & rebellion, Second is very Beatles themed and fourth is about Drugs, Sex & Las Vegas.
* CreepyMonotone: The Verses of "Lying is The Most Fun..."
* ContinuityNod: The opening of "The Ballad of Mona Lisa" music video has multiple nods towards the video for "I Write Sins Not Tragedies". This includes the view of church pews, the focus on Brendon's hat, and of course "closing the goddamn door".
** The clocks in the same video are all set to nine o'clock.
*** So is the big one in "Ready To Go".
** In the music video for "That Green Gentleman", near the end, a group of old men appear dressed up like the band did for ''A Fever You Can't Sweat Out''.
* DeadAllAlong: [[spoiler: Used at the end of the music video for "Nicotine".]]
* DeliberatelyMonochrome: The black and white variation is used in the music video for the song "Northern Downpour" as well as "Nicotine".
* Music/{{Emo}}: Calling them this around fans is considered taking your life into your own hands.
* EvenTheGirlsWantHer: In-universe in one of the bonus tracks "All the Boys". Not only does the speaker in addition to "all the boys" "love [the girl] madly," but so do "all the girls".
* FemaleGaze: Most of the music video for "Girls/Girls//Boys" probably qualifies
* FingerOnLips: For the video to "I Write Sins Not Tragedies", Brendon would cover his mouth for the words "whore" and "goddamn".
* GenreShift: Each album has had a pretty significant change from the last
** ''A Fever You Can't Sweat Out''- essentially NeoclassicalPunkZydecoRockabilly as noted below
** ''Pretty. Odd.''- [[TheBeatles Beatles-esque]] rock
** ''Vices & Virtues''- Pop-ish music
** ''Too Weird to Live Too Rare to Die!''- electronic dance and pop
* GirlOnGirlIsHot: This is present in the "director's cut" version of the "Girls/Girls/Boys" video, which features two women in underwear making out
* HeartbeatSoundtrack: A few times in their fouth EDM album, most notably in the beginning of "This is Gospel"
* IntercourseWithYou: A common theme in many of their songs (quite possibly AuthorAppeal)
** "Hurricane" most definitely counts.
--> ''I led the revolution in my bedroom, and I set all the zippers free.. / We said "no more war, no more clothes, give me peace," oh kiss me... / We are a hurricane, drop our anchors in a storm...''
** Also, "New Perspective". ''No more need be said, when I'm inching through your bed...''
*** Brendon even lampshaded another line at the [[http://www.youtube.com/watch?v=TYuW6S690Ow SDCC performance]]:
-->'''Brendon''': ''Can we fast-forward to go down on me?'' [[CaptainObvious That means a blowjob!]]
** One of the bonus tracks for ''Vices & Virtues'', "Kaleidoscope Eyes".
--> "I swear to God, I'd never heard a better sound coming out/Then when you're whimpering my name from your mouth "
-->''I've got an insatiable desire/For your/Insides''
** In "The Calendar":
--> "At night your body is a symphony, and I'm conducting..."
** "Casual Affair"
* LongTitle: Offenders include "The Only Difference Between Martyrdom and Suicide Is Press Coverage" and "There's a Good Reason These Tables Are Numbered Honey, You Just Haven't Thought of It Yet".
* LoveIsADrug: "Nicotine" from ''Too Weird to Live, Too Rare to Die''.
** "Nearly Witches (Ever Since We Met)" also has elements of this.
* LyricalDissonance: Most of ''A Fever You Can't Sweat Out''.
* MaleGaze: the "director's cut" version of "Boys/Boys/Girls" has a rather jarring example of this, which isn't present in the official release.
* NeoclassicalPunkZydecoRockabilly: ''A Fever You Can't Sweat Out'', fullstop. "Trip hop-cabaret-dance punk" was how Brendon Urie described it when asked.
* NewSoundAlbum: ''Pretty. Odd.'', causing the BrokenBase. ''Vices & Virtues'' was more in line with ''A Fever You Can't Sweat Out'' however.
** ''Too Weird To Live, Too Rare To Die'' is roughly 90% dance pop, with techno and dubstep influences, and a complete departure from anything they did before, barring "New Perspective". The closest song to any of their previous sounds is the piano and string ballad "The End Of All Things".
* NonAppearingTitle: All of the songs on ''A Fever You Can't Sweat Out'', but seen less and less with each successive album. Brendon has said this is because he had a hard time remembering the titles of the songs.
* OfCorpseHesAlive: Friend of the band Shane Valdés did a short called "[[http://www.vimeo.com/6219467 A Weekend at Pete Rose's]]" starring Brendon, Spencer, and Pete Wentz, with this trope as a premise.[[note]]Doubles as the music video for FallOutBoy's "Headfirst Slide Into Cooperstown on a Bad Bet"[[/note]]
* OffWithHisHead: Featured near the end of the "Miss Jackson" music video
* OneWomanSong: "Sarah Smiles", "Miss Jackson"
* PunctuatedForEmphasis: Why, the name of the band, of course!
* RevolvingDoorBand: Notable because they've never had the exact same official line-up for any two albums.
* SiameseTwinSongs: "We're so Starving" and "Nine in the Afternoon," but the latter is usually played by itself.
* ShoutOut: Many of the songs on ''A Fever You Can't Sweat Out'' are named after lines from Creator/ChuckPalahniuk novels. "Time to Dance", in particular, is one big long reference to ''[[{{Literature/InvisibleMonsters}} Invisible Monsters]]''.
** "Time to Dance" is interesting because if you haven't read ''[[{{Literature/InvisibleMonsters}} Invisible Monsters]]'', it seems like a song about teen pregnancy, and some of the lines that reference it seem to have little meaning in the scheme of the whole song (namely "hiding in estrogen and wearing aubergine dreams"). Brilliantly done double meaning.
** "Build God, Then We'll Talk" has a shout out to ''Theatre/TheSoundOfMusic''.
** "Lying Is the Most Fun a Girl Can Have Without Taking Her Clothes Off" and "But It's Better If You Do" are references to the movie {{Film/Closer}}- spoken in the same breath, no less.
** "The Only Difference Between Martyrdom and Suicide Is Press Coverage" comes from Palahniuk's ''[[{{Literature/Survivor}} Survivor]]''
** "London Beckoned Songs About Money Written by Machines" has a bridge which references lines from Palahnuik's ''Diary'' ("just for the record, the weather today..." is a reference to a line the main character often says), and the title references the Douglas Coupland Novel ''Shampoo Planet''("Torrid tunage from London beckoned- songs about money written by machines.")
*** This one may be unintentional, but the title also references Music/PinkFloyd three times; the band is English, and they have songs titled "Money" and "Welcome to the Machine".
** "I Write Sins Not Tragedies" also refers to ''Shampoo Planet'' ("I am writing a list of tragic character flaws on my dollar bills with a felt pen. I am thinking of the people in my universe and distilling for each of these people the one flaw in their character that will be their downfall--the flaw that will be their undoing. What I write are not sins; I write tragedies.")
** "Kaleidoscope Eyes" is part of a line from [[Music/SgtPeppersLonelyHeartsClubBand "Lucy in the Sky with Diamonds"]] ("Somebody calls you, you answer quite slowly,/a girl with kaleidoscope eyes.")
** The chorus of "Nearly Witches (Ever Since We Met)" was inspired by Patrick Süskind's ''Literature/{{Perfume}}''.
** Take one look at the chimney sweep part of the video for "Ready To Go". ''Film/MaryPoppins'', anyone?
** "Too Weird to Live, Too Rare to Die" is a quote from Literature/FearAndLoathingInLasVegas.
** Pretty. Odd. features an opening song that breaks the Fourth Wall by [[TheBeatles talking about performing as a band, which then transitions into the next song]].
* SpiritualSuccessor: ''Pretty. Odd.'' gets one in ''Take A Vacation!'' by The Young Veins, the band formed by half the band when they split. The album closely resembles the style of ''Pretty. Odd.''.
** Going off that, ''Vices & Virtues'' could be seen as a sequel to ''A Fever You Can't Sweat Out''.
* SteamPunk: The fashion and the items used in "The Ballad of Mona Lisa" are clearly influenced by the genre.
* StudioChatter: Shows up in the ''middle'' of "Miss Jackson"
** Also shows up at the beginning/end of most of the songs on ''Vices & Virtues''.
* SurrealMusicVideo: "[[http://www.youtube.com/watch?v=yCto3PCn8wo Nine in the Afternoon]]" has the guys waking up in color-coded bedrooms and that's around the time things stop to make any sort of sense. (It actually makes ''some'' sense if you know anything about the Beatles.)
** "[[http://www.youtube.com/watch?v=0xDf-_8KvGM Ready to Go (Get Me Out of My Mind)]]" seems to follow suit.
** The music video for 'Miss Jackson' has elements of this, probably because no one can decide what it's supposed to be about
* SuspiciouslySpecificDenial: "We're So Starving," where they assure the listener that they are 'still the same band'.
* TakeThat: "London Beckoned Songs About Money Written by Machines" is one aimed towards the then-fledgeling scene community (back when it was an offshoot of emo). This, of course, [[MisaimedFandom was not caught on by the MySpace crowd]].
** "There's A Good Reason These Tables are Numbered..." can be interpreted as a Take That to the subject of the song.
* TheLostLenore: Implied in the music video for "Nicotine".
* WhodunnitToMe: How the video for "[[http://www.youtube.com/watch?v=gOgpdp3lP8M The Ballad of Mona Lisa]]" plays out. [[spoiler:Mary did it.]]
* TitleDrop: Nonexistent in many of their songs (especially in their first album), but all of the songs on Too Weird To Live Too Rare to Die do this.
** Pretty. Odd. has "Nine in the Afternoon" "Northern Downpour" "When the Day Met the Night" "The Piano Knows Something I Don't Know" "Behind the Sea" "She Had the World" and "Mad as Rabbits"
* YourCheatingHeart: "Lying Is the Most Fun..." and "Build God, Then We'll Talk" have heavy references to cheating.
** Also implied in "I Write Sins Not Tragedies", and shown in the video
* VivaLasVegas: The theme of the fourth album, due to it being Brendon's home city and where he drew inspiration from.
