Cream Crackered

I felt it was a hard day today.  I really wasn't in the mood for it but head down and work through - Augen zu und durch, as we say here.

So I'm tired, and we get a bit of rhyming slang as a title - "cream crackered" = knackered, as in very tired.

I've not come across any rhyming slang in German but that could be because I've just failed to understand it.  So many cultural references just go over my head.
