Graveyard

This could be from the point of view of someone who is ending a relationship. The other person is fading from their life, and they recognize that they too are fading. Their ex-partner has "nothing to say" in their daily exchanges.

The second part is more of a paranoid accusation to them, that they've "been making plans" and are controlling their thoughts.

Or it could be literally them talking to someone they knew, who is actually dead.

Either way it's uncomfortable and creepy as all hell, and goes off the rails into batshit crazy territory! Fun stuff as always from the one and only Butthole Surfers!

The first version (where the vocal track isn't slowed down) has an almost gothic beatniky vibe, with Gibby's leering "You're rotting aWAAAY!! YEAHHH!!!!" as though decomposing is a sexy cool move, winking at you knowingly when he sees you heading to the speakeasy or swinger's club.

The sludgy riff, when sped up, is revealed to be a twangy surfy type riff, but when slowed down and met with Paul Leary's mesmerizingly Rain-Man-meets-Jason-in-the-big-reveal-scene-in-Friday-the-13th-part-4 solo on top, is rendered equal part funeral dirge and slowly shambling Romero corpse in black and white.

One could expect this to be the soundtrack at the real Munsters or Addams Family households, with our unhinged heroes talking to dead relatives from time to time, and engaging in psychic wars with their departed spirits!
