In Fitzgerald's This Side of Paradise, we have this passage:
MRS. CONNAGE: The poor boy looks so miserable every time he comes.
ROSALIND: That was one of those romantic, pre-battle affairs. They’re all wrong.
MRS. CONNAGE: (Her say said) At any rate, make us proud of you to-night.
I have no idea what "her say said" is supposed to mean. It doesn't even seem grammatical.
