Demon Reverse Sample

Um, Bloodbath did not exist when Demon was recorded...
Anyway, there is no definite answer to this so far, though I seem to vaguely recall that someone recognized the sample as some Mayhem song.
 
I reversed it once but I just came to the conclusion that it was insane mumbo muy jumbo.
 
I thought i posted a thread about this about a month ago, but never saw it back... he grunts something like "laughing at.. everyone"
