I use the word. I'm also not-so-coincidentally British.
I personally do not see it as being derogatory towards women. As others have pointed out, the same logic would apply to "dick" and yet nobody makes that argument (unless it's rhetorical). Just because you reference a "characteristic" body part doesn't mean you're trashing the whole gender. It just doesn't make sense to me. It's not like it's only said to women either.
Others may disagree. That's fine. That's why you control your behaviour and others control theirs. All we have to do is be considerate (eg don't drop the c bomb when you first meet someone new) and everything is good.
Also: are you American? In Britain, at least 50% of my c word usages are to friends. It's almost a term of endearment. So why should your cultural view of the word override mine?
Anyway, peace out cunts and cuntesses!
Wait, were both of those sexist or only one? 🤔
Yeah literally.
Although depending on context it may also be that you did something really bad, lol
Otherwise it means they think you can take a joke and probably like you at least a bit. If you're out drinking and it's said with a smile, you're officially one of the boys for the night
