She knows a bit here XD

and this: "they degrade each other in banter..." It's kind of a male way of bonding and camaraderie. I have no explanation for it really but just the way it is, and only a female around all of that all the time, understands what it is.

Now, that's not to say the wise thing as a male is to be able to discern when that type of banter is acceptable and when it's not, and also knowing which female friends understand it but that's an over-simplification of something that's far more complex to figure out in real life. So don't beat yourself up for it.

Above all that everyone has said here, be patient, and ease back into things with this friend. She'll probably come around and it will be fine, most people don't stay angry forever
