Hmm... burbot is not a catfish? Well it´s quite oblivious that it´s about some fish getting stuck in a net becouse "fisherman" and "net under the ice" appear at the text for few times.
Black Roija, it think it´s some kind of a dark side in your mind or an animal instinct or something like that. "Demons hunger your Black Roija" it must be somekind of a beast inside a man. Actually i have no idea on this one just guessing.
Tordah. This is the hardest one. I dont belive the "hooah" thing, no offence but it sounds kinda stupid if you put "hooah" in the place of "tordah" in the song. It´s not a finnish beer or any beer i belive. Tordah must be some kind of a place where the guy in the song can go by drinking all that moonshine away from social pressures. "To be acceptable, to be respectable, to be normal, To be a decent man. But I'm neurotic, I am vehement, I am withdrawn, A psychotic man. Unsuccesful, hesitant" Yet again no idea really. I hope the band will tell us if we dont find out.
