Boy this has been an interesting read!
SewingSew, circling the drain (CTD) has the same meaning in hospitals too....
Some of these I've heard of, most are new to me though. Had an elderly aide (from W Virginia) when my gram was getting on who could often be heard saying "Oh, bless her pea pickin' heart." Found out years later from a co-worker that the aide was not being nice when she said that about us!
DH, who is 50, says "Crazier than a s**t house rat" a lot.
My dad also says "If you're born to be hung, you'll never be shot."--memory brought back by previous poster-thanks!
