* BigLippedAlligatorMoment: "Some Things Should Be Left Alone", lyrically. Derek even mentioned that he knew it would be a bit jarring to switch from a concept album about a journey into the world of the dead gone wrong to a song about a demon brutally murdering the people who were unlucky enough to encounter it, but since it ''was'' Frank's contribution, they just opted to keep it without a second thought.
* CrowningMomentOfFunny: Frank Mullen is a veritable wellspring of these. Chief among them is [[http://www.youtube.com/watch?v=DXvGodNnKKs his drunken rendition of "New York, New York"]], as well as [[http://www.youtube.com/watch?v=wz_zrFlKAh4 one of his frequent impromptu standup routines as shown here]], but really, go to a Suffocation show and there's a chance that Frank will say or do something highly amusing.

-->'''Hobbs''' (while very, very drunk): "Do I have to show you guys how to make another 'L' again? After twenty years? After twenty years! I have to show you how to make an 'L'! Jack 'em up! Look, this is three bottles of straight-up ''bourbon'' later! Later! '''LATER!'''"
* EnsembleDarkhorse: Doug Bohn. While Smith and Culross are the Suffocation drummers who get the lion's share of the press, there are more than a few Suffo fans who prefer Bohn to both due to his uniquely groovy and deceptively complex style.
* FaceOfTheBand: Mullen and Hobbs share these duties.
* FandomRivalry: Over the years, the split with Mike Smith has spawned one of these between his fans and Hobbs' fans. While plenty of Suffocation fans don't care, the Smith diehards see Hobbs as a lazy stoner who is forcing an InNameOnly version of Suffocation to limp on well past its prime, while the Hobbs diehards see Smith as a toxic, abusive bully who didn't actually give a shit about the band beyond what it could do to boost his ego.
* FirstInstallmentWins: Generally subverted; while there are plenty of fans who consider ''Effigy'' to be their peak, there are also roughly just as many who would say the same for ''Pierced''.
* ItsShortSoItSucks: Apparently, this was one of the non-production criticisms against ''Breeding the Spawn'' at the time of release. Rather ridiculous, really - it was only one track and two minutes shorter than ''Effigy of the Forgotten''.
* ItsTheSameNowItSucks: Another of the non-production criticisms against ''Breeding the Spawn''. This stance more or less disappeared after a few years.
* NightmareFuel: Many of their song lyrics and music videos have a high quotient of this, with [[https://www.youtube.com/watch?v=EEYSU4XGLpI the video for "Cataclysmic Purification"]] being a standout example.
* ReplacementScrappy: Downplayed with Ricky. Almost all fans agree that he does do a very good job, but just wish that it was Frank up there instead. Generally subverted with Kevin, as the general consensus with him was "not Frank, just as good"; while most fans still missed Frank and there are a few who refuse to accept anyone other than him, they were generally been perfectly willing to accept Kevin as an extremely strong substitute, whereas the prevailing opinion with Ricky was "good, but comes up a little short". Also subverted with Eric Morotti; while plenty of fans still prefer either Smith or Culross, the general consensus is that he is a great fit for the band.
* SeinfeldIsUnfunny: Any death metal fan who knows anything will cite ''Human Waste'' and ''Effigy'' as all-time classics, but few people can fathom just how much those albums changed the face of death metal.
* SignatureSong: "Infecting the Crypts" and "Funeral Inception".
* SophomoreSlump: Big-time. Some aspects of ''Breeding the Spawn'' have been VindicatedByHistory; particularly, the song-writing, which was attacked at the time as failing to bring any new element to their sound, is now considered to have been among the most technical ever produced by the band. However, to this day it's generally agreed that the production and engineering is a total failure that brings the album down several notches.
* ToughActToFollow: All Music's review of ''Breeding the Spawn'' posits that the album would've suffered this relative to ''Effigy of the Forgotten'' even if there hadn't been glaring flaws in the production, due simply to the monumental impact ''Effigy'' had on the death metal community. Needless to say, there's plenty of reason to debate that assertion given how highly the songwriting on ''Spawn'' is now regarded.
