zetsubou also can mean hopeless so I think "zetsubou billy" is just calling a guy named billy hopeless meaning there is no hope. This song was written for Death Note but as the guy said before KIRA is another word for Killer. Kira from death note possibly got his name from that and it's just a huge coincidence that this song has that word in it.
