The song appears to be about an alcoholic. While it seems that the “you” the narrator is addressing could be an unrequited love, it may also be the alcohol itself that he’s speaking to.
Sweet debility; the Macallan in my glass
Honey beads from those ardent eyes
So here I sit, flooded in molasses
Every dollop of sweat swells in your light
So call me what you will, just calm me
Call me what I am, I’m yours
Laundered each saccharine stain
Every word until the purity burns
The sugar drips until your name soaks in my brain
I can’t stand to be rid of you
So call me what you will, just calm me
Call me what I am, I’m yours
