Take Back song meaning

With Take Back the narrator expresses the hate he feels towards some person that "pushed him once too far again". This person has hurt him so much that they pretty much get under his skin now. He’s dreaming of revenge as he repeats “can't take, can't take, can't take anymore”. The anger is so strong that he’s willing to play dirty and stick the knife right into their back. Whatever it takes to take back what’s his - his pride, his dignity. "Expect it when you're least expecting it" - he's not going to stop.
