Lyric discussion by Greggor 

Cover art for Slut lyrics by Velvet Acid Christ

I think this song is about a girl(slut) with a S/M personality (well it may sound absurd ... beat your ego black and blue)

People that know her see her as the pleasure in their lives. (I will be your doll) (I will be your hole) (I will be your toy)

But then she consumes the lives of everyone that she dates/does and ruins them. (I will remove your heart) (I will abrade your soul) (I will tear you down with the twist I bring) (I will burn your world) etc

So like the person above me said, it's about a person who is your every pleasure and your every pain at once.

Also, the most epic line in any song ever is "I will be your never ending, unbefriending, self-expending, moral-bending thorn". :)
