Lyric discussion by PirMOnk 

The first half of the song is comparing one's brain to a burger and the heart to the coal. In this line Issac is conveying the idea that sometimes we let our emotions, our heart, get the best of our rational selves, our brains. but to rebutt this claim

In the second half of the song Issac employs the Bitter Buffalo metaphor. He is conveying the idea that sometimes people give up on what they belive in their heart because of something their rational brain says. Issac says. Don't be rational, let your buffalo heart love and don't allow it to be bitter because of what your head tells you.
