[King of Snake]

Always a hard thing to determine with Karl's lyrics, as the lyrics in one song may be about a lot of different things, are about nothing in particular. Most of his lyrics come from roaming the streets of whatever city he's in and writing about stuff he sees or conversations he overhears, of course all intepreted trough his own particular style of observation and interpretation.
In moaner, there's lots of roaming the city streets stuff, and maybe a story about frustrations with a relationship/love.

I don't think there's really much sense in trying to figure out what the lyrics mean per se. Maybe more interesting would be to try and imagine the situations and places he was in when he wrote it. Were they his own feelings, or interpretations of something he was observing? Maybe/probably a bit of both?
