Word 2007 won't let me read this. "Rock paper" somehow implies the existence of scissors...

(What, apart from that, does it mean?)

Rock - solid, reliable... BrE slang, and me being flippant, as per usual.
Just a few quickies: properly so called set phrase (!) stock epithet prime object, primary object, principal object hard and fast

Thanks for some excellent examples.

And I asked:

Rock - solid, reliable... BrE slang, and me being flippant, as per usual.

When my thirty-somethings were at school, "rock" meant "very hard": e.g., "The history paper was rock!" IIRC, "solid" acquired the same meaning, but ICBRW.

Well, that's sort of what I meant. As a piece of scholarly research I felt it was a well tasty paper.
