Morbid Angel
Pete Sandoval may have invented "dee blass beat," but the rest of the band arguably invented generic Florida death metal. To be fair, they do have a few good songs ("Chapel of Ghouls," "Rapture," "God of Emptiness"), but everything else is the most boring, awful shit I have ever heard. I mean this band makes Deaden, Jungle Rot and Waco Jesus seem like brilliant virtuosos! To make matters worse, there are many bands that play Morbid Angel better than Morbid Angel themselves, for example Angelcorpse.
PS I have a Morbid Angel tattoo, lolz @ me.
Carcass
Like Terrorizer, this band is worshipped by nerds everywhere. Everyone likes to establish their metal cred with that old saw, "I only like their early stuff!" and say that "Swansong" sucks. However, it is expressly forbidden to point out that even their early albums are basically just limp hard rock, watered down with the melodic parts that would become the entire basis of their style. The truth is that people who like Carcass are pussies that want to pretend they're listening to brutal grindcore but in reality are jamming what amounts to soft rock with a pitch shifter. For example, listen to "Tools of the Trade," which many nerds think is the best Carcass album. It's so full of melody and slow parts that it might as well be fucking Big Drill Car or something (Big Drill Car were way better, though). No slam riffs, dreadlocks, and pink guitars? Sounds pretty false metal to me.
Japanese grindcore and hardcore
If you like this destestable genre, chances are good that you wear rapist glasses, still buy vinyl, and beat off to anime snuff porn. And post on the Relapse board. People who are into this stuff also seem to be into all kinds of other creepy/dorky shit like Italian horror movies, Japanese gore movies, pro wrestling, and noise. Oh, and having Asian girlfriends/wives (Japanese is ideal, but they'll settle for any Southeast Asian broad they can lure into their web of creepiness). In general, they just won't shut up about the weird shit they're into and have no ability to detect your complete lack of interest. These losers are truly the bottom of the barrel in the already pathetic world of metal fandom.
At The Gates
The 90s were full of awful metal bands that played "melodic death metal" like this terrible band, and this decade has been full of even more awful hardcore bands that rip those bands off by playing boring tremolo riffs and screaming in their girl jeans. Also lots of them are Christian, which makes the whole phenomenon that much worse. ATG and the rest of this wretched genre is a botched attempt at combining two things that just don't belong together: melody and death metal.
Assuck
I am pretty sure I've discussed how lame this band is before, but I can really never get enough of it. Assuck was very popular in the 90s with poser hardcore kids that had never heard blast beats and death metal vocals before. Much like when you were in junior high and would sell your soul to have any female human being touch your penis, regardless of how hideously ugly she might be, Assuck fans become giddy at the sound of Rob Procter's weak, gay blast beats because they just don't know any better. You can only imagine how floored they would be by, say, Benediction! And don't even get me started on the rest of this awful genre like Destroy, Resist, His Hero Is Gone, or really third-rate, bottom of the barrel bands like Reversal of Man. Most of the assholes that listened to Assuck in the 90s went on to be in indie rock bands and get Morrissey tattoos.
