Slayer: Apparently writing lyrics is a quick process

Kerry King is writing some new words for a Slayer record. Surprisingly, he's not blocking out much time in his diary:

"If I get off my ass and start writing again on the road — since we've been in Europe, I keep trying to work on lyric ideas, maybe some leads, and fixing songs that didn't work correctly — it should be a real quick process."

Really? Thinking up rhymes for "blood", "grave", "misery" and "antichrist" is such a speedy process? The creation of yet another song about not showing mercy is something which one can do while waiting for a PopTart to cook? Whoever would have guessed?
