Re: I don't know what it is about Chastity...
I'm sure you will find quite a few nuns named things like Sister Mary Grace or Sister Hope and whatnot, but I will personally eat my hat if somebody can show me a Sister Chastity. See, even the nuns know it. lol
Another factor working against Chastity's image is how often it's speled Chasity or Chassidy or Chassittee.
