Oh who said life was easy
who said life was fair
who said nobody gives a damn and nobody even cares
The way you’re acting now like you left that all behind
You've given up, you've given in
Another sucker of that slime

I have drawn a blank trying to define what the expression "sucker of slime" means here.
