I've heard it refers to the "supermarket mix", I think Tom Elmhirst said it. It's those elements that only make its through the poor tannoys and din of a supermarket.
Edit: I looked it up and it was Tom Elmhirst. He also has my new favorite quote about working alone:
"I need my space at the beginning because it’s going to be a mess at first -- you don’t watch someone in the bathroom, you just want them to come out with their hands dry."
