Anvilicious: Pretty much the only way the Dirt album could be less subtle is if it consisted of nothing but Layne screaming "HEROIN RUINED MY LIFE" over and over again for an hour.
Broken Base: Fans are divided on whether Duvall is any good or not.
Covered Up: There are people who don't know "Them Bones" or "Angry Chair" but have heard versions of them in Doom II: Hell on Earth.
Epic Riff: Many - the talk box guitar opening of "Man in the Box", the main riff in "Rooster", the bass intro to "Would?", and the distorted guitar line in "Grind" are some of the best examples.
The bass riff in "Angry Chair." Full stop.
Face of the Band: Due to the problems stemming from his heroin addiction, Layne Staley was pretty much this, for better or worse.
Fan Dumb: Often stemming from debates about Duvall, but that aside there's still no shortage of this.
Gateway Series: Alice in Chains was an intro to Heavy Metal for many older metalheads, and served as a gateway to many heavier bands and subgenres of metal.
Growing the Beard: Most fans will agree that Dirt was when they truly found their voice. While Facelift is still loved by the fans, many complain that the second half of the album sounds too much like their hair metal roots.
The Law of Fan Jackassery: Ever since the band's decline from popularity in the mid '90s, the fanbase has fallen dead square at the peak.
Probably has to do with the fandom containing the worst elements of both metalheads and Grunge Disco Dans.
