They never heard of classic rock." pretty much confirms it.
The superficial idea behind it is to know when to recycle your garbage: i.e., it's good to re-do some things, but there comes a point where you can't re-use it any more and you just throw it away, because it's garbage, junk, strictly refuse, rubbish.
