This song is just pure aggression. Musically and lyrically it is meant to be the metaphorical equivalent of just punching a wall repeatedly. I think the is obviously conveyed by the chaos of the music and how dark these lyrics can get.
With the crush of the cartilage
Those black ruptured gums
Who would have thought
The site of your protruding tibia out your front
Makes it worth not eating well for a while
With your abundances thrown out
Spread out like a canvas
All the way down this average suburban road.
