YMMV tropes about the band itself:
- Award Snub: The 2003 Grammy awards nominated both Slipknot and Stone Sour in the Best Metal Performance category for "My Plague" and "Get Inside" respectively, giving Taylor and Root a 2/5 chance of taking home an award. Korn won that night (Slipknot won three years later for "Before I Forget" while Stone Sour is one of the most nominated bands without a win in the category's history).
- Broken Base: ...over the shift away from their nu-metal beginnings.
- Jordison's departure from the band and Grey's death also broke the fanbase quite a bit. Jordison and Grey wrote a good chunk of the band's best material and some are worried that the rest of the band won't be able to match up to their song writing.
- Every time they change to new masks. Many fans have been rather disappointed with the new masks following Jordison's departure, especially with Corey and Sid's masks.
- Face of the Band: Jordison and Taylor mostly...which is sort of ironic given their schtick.
- With Jordison out, Taylor, Root, and Crahan fit this role now.
- Fandom Rivalry: Mostly with Mushroomhead fans. Juggalos and Maggots are also rivals somewhat, even though Slipknot's members are Juggalos. Insane Clown Posse and Slipknot are actually mutual admirers, although ICP is not fond of Slipknot's decision to call their fans "maggots".
- Heartwarming Moment: Jordison's Facebook post on the anniversary of Paul Gray's death.
"Hey Paul, it was so great hanging out with you yesterday and today. Talking and reminiscing about old times and seeing you respond with some of the strongest gusts of wind I've ever felt"
- After the tattoo story below, Taylor talks about how incredibly cathartic the experience was and how his wife is such a huge source of inspiration and strength for him.
- It's Popular, Now It Sucks: Being one of the most popular metal bands ever, this is a given.
- The hidden track "Porn and Weed" on Slipknot, in which the band is recording themselves watching a scat porn video, including at least one member throwing up. This may also Cross the Line Twice for some, especially due to some of the comments the guys make.
- The band released a box set that included a DVD in honor of the 10th anniversary of the release of their first album on September 9, 2009, or 9/9/09 (a reference to the collective name "the nine"). The very first scene on the DVD, following a foreword by Crahan, is of Wilson vomiting for about a minute and a half.
- Tear Jerker: The live press conference held by the remaining eight members of the band the day after Gray's death. Listening to Jordison, Taylor, Crahan, and Wilson hold back tears as they spoke of how much they loved their fallen brother was insanely hard. Worse yet was when Thomson, upon being passed the mic, stared at the table in utter silence for a few moments before passing the microphone on down.
- An episode of NY Ink had Taylor getting a tattoo in memory of Gray and he spends the entire time bawling his eyes out to his wife about how much he missed his friend and wishes he was still here.
- True Art Is Angsty: Outside the band, Crahan is a prolific artist; his work pretty much lives and breathes the trope.
YMMV tropes about the music:
- Ear Worm: "Before I Forget," Wait and Bleed," and "Duality" have extremely catchy choruses.
- Epic Riff: "Psychosocial", "People = Shit", "Before I Forget", etc.
- Gateway Music: To some.
- Fridge Brilliance: In the Dead Memories video, Paul stops mirroring Corey when Corey raises his hand. Paul was left handed.
- Growing the Beard: Depending on how much you hate nu-metal, the group's move to a more traditional metal sound with more guitar solos and less intrusive use of samples and turntabling could qualify.
- Magnum Opus: Either Iowa or Vol 3. So much so that the new album is trying being labeled a fusion between the two records.
- Misattributed Song:
- Signature Song: Either Wait and Bleed or Psychosocial.
- Most Wonderful Sound: "8. 7. 6. 6. 6. 5. 4. 3. 2. 1. Null."
- Nightmare Fuel: The song "Iowa" is basically nightmares given auditory form. Other creepy songs by them include "The Virus of Life", "Tattered and Torn", "Prosthetics", "Scissors", "Gently", and "Purity."
- The video for "The Devil In I" is this involving a lot of body horror and mutilation.
- Tear Jerker: "Snuff".
- "Vermilion Pt. 2".
- What Do You Mean, It Wasn't Made on Drugs?: "Dogfish Rising" from MFKR. So very much.
