Lyric discussion by forallthecows 

to me this could be about those smart ass wise guys who use words to provoke others, and uses words as fists (if you get what i mean) "You're so clever you tear us apart Then masquerade it as art, not smart. "

'gunman' sees right through this guy, and compares himself to a rabid animal (lion in a cage, angry ats etc), if this wise-guy even thinks about provoking gun man, he's gonna die by the tooth and nail.

"It don't' matter don't try to explain You're just another dog to be trained/choke chain You're gonna die by the tooth and nail If you catch a tiger by the tail/Don't fail"

it might be deeper than that, but there's i get the sense of bitterness and references to mindless violence
