Here is a new word for your enjoyment: thotistic - adj. - having the qualities or proclivities of a thot; the condition of being a thot. "Please excuse my sister, she's thotistic, which is why she's wearing a niqab.

Addendum: Consider using burkas and niqabs as a punishment or shaming tool for females. I think it is much better than as a blanket (pun intended) condition for females in public.
