Earlier quoted context omitted.
If my reading of her account is correct, the person who got fired was suggestion that Adria "check out his big dongle" which is a very explicit sexual joke directed at a specific stranger (her). The joke that she's making there is that her male friend should stuff socks in his pants to shock the screening TSA agent. This joke is not targeted at anyone in particular. The comment she's replying to is a factual descript…
This was a private conversation between two friends, none of whom referenced her or even knew she was listening.
Are you sure? How do you know?
If my reading of her article is correct, and she was telling the truth, then she did not think so. That does not mean that she was correct. And with a he said, she said situation there is no chance of sorting things out. But your unsupported assertion of fact is not necessarily true.
Her article is at http://butyoureagirl.com/14015/forking-and-dongle-jokes-dont... if you want to read it to decide for yourself whether I am reading correctly.
Here is the scenario that I read from her description. She's sitting one in front. 3 guys are behind and (if she is turned) to her right. Guy #1 who is behind is talking about a presentation, she turns and agrees with him, and during their discussion he talks about forking a repository.
Guy #2 is to #1's left (on the right from her view), and begins making sexual jokes about forking with #3 riffing off of that. Then shortly after they riff off of a comment from the speaker and joke, "You can thank me" then start talking about big dongles.
Therefore their sexual jokes were based off of their overhearing HER conversation, and so they had every expectation that SHE would hear THEM in turn. Furthermore I get the impression that even though she was not looking at them, she believed that they were implicitly ADDRESSING HER. (I am not saying that this belief is correct, merely that this is my impression of the situation as she remembered and described it.)
If so, then in no way that she would have believed that this was a private conversation. Nor is it tenable that they were accidentally overheard by her. Nor is it a surprise that she took it personally.
Of course we all adjust memories of things that happened to be clearer cut than they were. There was a lot going on. I was not there - she may have misunderstood the interaction. But what she described is both a plausible scenario, and one in which her upset makes quite a bit of sense to me. And one which runs absolutely counter to the narrative that this was simply a private conversation that she accidentally overheard and overreacted to.
