As far as I have understood the song is about a relationship that comes back to life.
These are the parts I understand fully;
"Kill your bizarre mindset, fuckhead, soldered to a three-layered concrete brainwave castration"
MEANING; Stop being so bizarre, kill off your way of thinking like a brainwave castration or against a three layered concrete wall.
Walking backwards home with you
MEANING; Starting all over again.
