I just don't get that at all from the snippet quoted, but I can imagine how the larger context of the song might flip the meaning of things around - but I don't know the rest of the song and was going only based on the words in the article with no way of knowing how those words were performed. :)
I suppose the use of "toast" could be a clue that he actually means some kind of respect, but then why respect "douchebags" and "assholes" etc? So my reading put large quotes around "toast" in the way you might "toast" someone sarcastically who just made a giant mistake or something.
If the greater context of the song established that the voice was being sort of facetious here, then I can see how my interpretation could be almost exactly backward - but again, without some grander context, I really feel I had no way to know that if that is indeed the case.
Side note: Over the years I've noticed that either, A) I just suck at interpreting song lyrics, or B) song lyrics are often purposely designed to be ambiguous. I suspect some of both is at work here. :)
