Six feet under? (Stevie related question)

[Villavic]

So I was surfering on cable channels and stopped a bit to watch this Six feet under serie. I think it was the second chapter, I caught it when the family was in the kitchen and I heard a phrase, something like "... slept with Stevie Nicks"

So I decided to stay and watch the whole show. IT was cool, first time I had watched it.

Then several minutes later, mother was on the kitchen and daughter entered to check in the refrigerator and asked if there still remain those "Stevie Nicks rapsberries"

What are those Stevie Nicks rapsberries ????? Does anyone know the story behind it???
