It's genuinely crazy to see topics and people writing on the internet from so longer ago. While I can almost guarantee I will never return to the comment I'm about to post (if it even works) and that fact that none of the original people to post will see this- it's still so fascinating to see.

Anyway, my belief of what it meant was already answered dozens of times, it's to be lashed until you're unconscious. Although you could have the direct meaning, I don't see it fitting the song as well.
