What do you think is male version insult for cunt?

No idea...

How about the female version of "thinking with the other head?"

I see it as a unisex insult. I call men and women cunts. Gender equality

Everything’s a cunt, man, woman, table I just stubbed my toe on, me when I drop something, my dog when she decides to drop a shit out in the middle of the road.

Dickhead?
