Sweet summer child, it's been more than sporadically used in the American South long before Game of Thrones, and well within this century. GRR Martin just used what was already a well known phrase, and maybe the show made it trendy but he didn't "coin" it in any meaningful sense.

Do you have documented evidence for that? That’s the usual reaction (and mine, too, given my unfamiliarity with GoT), but every discussion around this turns up a few hits from the 1800s, and then basically nothing until GoT came out. Or maybe my info is out of date?
