I think this song is a kind of sequel to My Last Words from PSBWB. Remember it was about Russian roulette? Well, there are a lot of things in these lyrics that point to the same thing. The main character plays the roulette because he's bored, and because he wants to see blood. He believes he'll never die and that it's impossible for his opponents to win.
"Inside the abattoir
The cover charge is somebody's gotta die
Now I hear you screaming out for mercy
Last man that's standing wins the fight"
