Crosses the Line Twice - Oh so very much. Examples of song titles: "Entrails Ripped from a Virgin's Cunt", "Fucked with a Knife", "Necropedophile", "I Cum Blood".
The lyrics of "Absolute Hatred" can be interpreted as racist.
High Octane Nightmare Fuel - Several of their songs could qualify, but the best contender(s) would be the album art.
Misattributed Song - Cannibal Corpse never did a song with GWAR called "We Are Your Enemy"; the song was done by Dying Fetus, and Dying Fetus alone. And "Damnation" is by Morbid Angel, not Cannibal Corpse. The latter mistake occurs much less, mostly due to Morbid Angel being the most famous death metal band aside from Cannibal Corpse themselves.
Squick - Most of their album covers, especially the uncensored cover of Tomb of the Mutilated with its depiction of corpse cunnilingus. A lot of their songs count as this trope as well.
