As a Californian who grew up playing long nights with my Aussie friends (AUS connects to CA for their Internet so we get them a lot at night):

I'm one of the Americans fighting for the use of "cunt" more!

People are shocked at first when I use it but I'm usually onto the next thing so fast, suddenly say it in an Australian accent, and am very clearly not being negative when I say it most times (big smiles) they usually pick up that it's not mean.

They do ask where the fuck I learned to use it though and it took my wife literal years to adjust
