is this completely original?

A Crown for Cold Silver - Alex Marshall

"She couldn't wait for him to meet Choi -- when the laconic met the terse, who knew what might go unsaid."


I've never heard this particular word combination before.  Has anyone?


it feels a little bit genius to me.  (Yeah, I know I don't get out much.  And I'm weird.)

And maybe it has to be taken in context.  But I love this sentence.  And several others that I haven't bothered to   share.
