For a slur to go deep like that it has to actually mean something in a historical context. N word was often used in slavery and jim crow times. I don't know if I could think of a single word to incapsulate it, but something harkening back to times of female subjugation would probably work best. Something along the lines of "Baby maker" "Sack of holes," etc. Something better than that of course, but still. "Whore" or "Slut" are things that ring of an age of sexual freedom, which is the opposite of what we're trying ti bring to mind.
They are offended by anything we can call a lady. Hell, they were probably offended that I referred to them as "ladies." I don't know why or how, but as long as we are the wrong side of them emotionally, there is nothing we can say that is less hurtful. That said, I think we're good on insults.
Cunt is the closest word I can think to fit this.
Pretty vulgar in most social settings , doesn't have the discriminating feeling that "nigger" carries though.
You'd need a phrase or to invent one but that would just be throwing random shit together.
TL;DR Cunt fits a holes title best
I see what you are trying to say here. The N word has its weight behind it due to its history. None of these words for foids currently cut it because they don't have any history attached to them.Unless we have such an historic and traumatic event esp. for foids, I guess such word won't come into existence.
