Been laughing through this whole threadI thought biddy was because they stand around chatting and clucking like old biddies when they're older.
BattelSyrup, that's pretty much it...most of us older women are a bit set in our ways, have been raised old school, so the chatting would prolly be about that short dress "she" wore to church, as in " can you believe, so and so, wore THAT to CHURCH?" and the clucking would be the actual cluck sound, as in " no I can't believe she wore that short of a skirt to church"...only not actually saying it...just agreeing...it's an old person thang
