I love Perona, and I think she cuntified Zoro's attitude on some levels.
I think Zoro would never want to rest when he was taining, but Mihawk would force him to rest, so Perona would take him shopping with her. And after their first shopping trip fiasco, she gave him some rules, like if she picked on another bitch he had to back her up.
And I think Zoro took that with him, so whenever a Nami insults some other b, Zoro is there in the back like
-right -busted -she got yo ass -I would leave if I were you hoe -snatched yo wig -period -on cunt - negative aura
And he doesn't even know what half of these mean, but he sometimes says them unconsciously when he hears insults being thrown at someone.
