I'd say this song is about taking a look back at all the fucked up shit you've done over the past few years, and tallying it up, realizing how bad it is, but still laughing about it. Laughing about the fact that you're still around. Then later in the song it goes on to observe other people, who delude themselves in different ways, how they think they're being saved. Then the last line is about realizing this is the train you've put yourself on, it might not be the best thing in everyone's eyes, but it's working for you, so fuck it, you've lived to see another day.
