Do you know what Cards Against Humanity is? The moderator puts out a prompt card like "Santa ran out of coal, so this Christmas he is stuffing bad kid's stockings with __________". And then other players anonymously submit cards to fill in the blank with words on them like "AIDS", "A starving African child", "Michael Jackson", "White Privilege", "Anal Beads", "the Holocaust" and etc. The idea is to hit every awful thing you could possibly say. People find this funny because it has all the jokes you can't make in it because they are so horrible. Sort of like dead baby jokes.
I would assume I could joke about a dongle with such a person.
This is basically arguing the same as saying that because she would discuss her breasts in one context with a doctor, you should be able to discuss them with her in any context.
It's such a stupid claim on your part that "context doesn't matter" and you're still not doing anything to back up your claim that she would "get people fired" for playing CAH - especially when she did play it and did not raise any complaints about it.
