* BrokenBase[=/=]FanonDiscontinuity[=/=]DorkAge: the fan reaction to ''Zeitgeist''. ''Adore'' was also considered something of a DorkAge, though it was one of their most critically acclaimed albums and has come to develop a [[CultClassic cult fandom]] over the years.
** You can easily start a debate among fans as to whether or not the second time around, starting from ''Zeitgeist'' to ''Oceania'' and whatever comes after that, is considered truly The Smashing Pumpkins or just InNameOnly.
* CrowningMomentOfHeartwarming: "Luna" and "One Diamond One Heart," as well as "Pinwheels."
* CrowningMusicOfAwesome:
** From ''Gish:'' "I Am One," "Siva," "Snail"
** From ''Siamese Dream:'' "Cherub Rock," "Soma," "Luna," "Disarm"
** From ''Mellon Collie'' (disc 1): "Tonight Tonight," "Zero," "Here is No Why," "Muzzle"
** From ''Mellon Collie'' (disc 2): "Where Boys Fear to Tread," "Bodies," "X.Y.U.," "Thru the Eyes of Ruby"
** From ''Adore:'' "Ava Adore," "Daphne Descends," "To Martha", "Appels + Oranjes", "Pug"
** Even ''Zeitgeist'' had "Doomsday Clock."
** From ''Oceania:'' "Quasar" was the moment at which people realized the Pumpkins really were back.
* EnsembleDarkhorse: "Drown" to the ''Singles'' soundtrack. The song received airplay despite a) never being released as a single, and b) being the only song on the album by a band from outside Seattle.
** "Muzzle" is one of the band's post popular songs despite only being a promotional single, never even getting a full single release or music video.
** ''Mellon Collie'' has a lot of these: "X.Y.U.," "Thru the Eyes of Ruby," "Bodies," "Where Boys Fear to Tread," "Jellybelly," and "In the Arms of Sleep" all arguably qualify.
** "Set the Ray to Jerry" is quite popular despite never being on a full-length album (it was the closing track on the ''1979'' EP).
* EpicRiff: The live version of "Daphne Descends" has a truly glorious one.
** Also, the intro and main riff from Cherub Rock.
** "Zero".
* FaceOfTheBand: Billy Corgan, May also be crossed with IAmTheBand as he's the only original member left.
* FanCommunityNickname: "Ghost Children", based on the story of ''Machina/The Machines of God''; also, "Pumpkinheads".
* JerkassWoobie: Corgan may be a jerk at times (as attested by throwing {{Pavement}} off a festival bill because their song "Range Life" mocked his indecipherable lyrics, his transphobic insults against custom pedal manufacturer Devi Ever, or his bizarre declaration about wanting to "piss on Radiohead" and constant insults thrown at his former bandmates), but he has had a pretty tragic life, having grown up in a horribly abusive home, spending much of his childhood taking care of his disabled brother, and dealing with severe depression, even contemplating suicide. He may be a control freak and a jerk but he seems to be desperately holding onto the only good thing in his life.
* MagnumOpus: Usually considered to be either ''Siamese Dream'' or ''Mellon Collie''.
* MemeticMutation: "But despite all my rage, I am still just a rat in a cage"
** "But despite all my rage, I am still just NicolasCage."
* UncannyValley: The "Ava Adore" music video. Creepy dancing, along with the stillness of everyone in the background and Billy Corgan's [[LooksLikeOrlok Nosferatu look]].
* SignatureSong: either "Zero," which they played on ''TheSimpsons'' or "Today," which Billy performs in ''Guitar Hero: World Tour''.
* VindicatedByHistory: Corgan predicted that this would happen to ''Adore'', and over a decade after its release, he appears to have been right.
** Corgan has also mentioned that he regrets having described the album as "electronic", believing that this distorted the way people perceived it, and once commented that he believed that simply referring to it as an "acoustic" album would have caused less trouble (the album only really had one electronica song while the singles retained "1979"'s use of technology.)
** The band as a whole. They were TheScrappy of alternative music for a while during the '90s for their ArenaRock influences (and Corgan's general dickery didn't help), but are much more positively viewed nowadays.
* {{Wangst}}: Billy Corgan is very prone to this in his blogs and interviews. It seeps into the lyrics sometimes, but is generally considered forgivable because of the music.
