Ok, so since they've all know eachother for a long time, I think that Aizawa and Kayama call eachother, like, the worst of names.(ex: Aizawa calls her slut, whore, bitch,etc...)(yes I know it sounds bad but stick with me)
It's like when you've been friends with someone for so long you just make those kinds of jokes.
(I was reading a fic and this kept happening and I thought 'That's true friendship right there.')
