Lyric discussion by lord_abortion 

"I slit guts guts and free the moistest facces Corrupt the corpse and seize the choicest pieces Her alabaster limbs that dim the lit carnal grin Vaginal skin to later taste and masturbate within"

First off, this part clearly discusses him murdering his victim, then cutting the body up.

"Dub Me Lord Abortion, the living dead The bonesaw on the backseat On this bitter night of giving head A sharp rear entry, an exit in red Lump in the throat, on My come choke The killing joke worn thin with breath"

I believe that this part is talking about how he has sex with his victims before killing them. "a sharp rear entry, an exit in red" I think means the knife he used to kill the person with. A sharp rear entry(the stabbing) an exit in red(the knife covered in blood as it exited the body.
