What is "sisterhoods"

Usage examples of "sisterhoods".

I have no love for secret societies and sisterhoods, and what I know, I reserve the right to tell as I choose, to whomever I choose.

And with all respect, I find it hard to believe that these rival sisterhoods, or whatever they are, will behave like some old legendary dictator or brainwashing expert and offer them a choice between death or dishonor.
