I had to login to HN which I have not done in many months just to say this to the young generation.
The title is from a meme. Like before the memes of today, when a meme was an image around a black frame with white text.
It usually goes "I accidentally a <thing>".
Until I read all the way down here to the bottom of the comment thread, I was thinking about the older people who didn't get this reference since I've been hearing it for decades. But now I see, thanks to your comment, that it is I that is the old one, and it's the youngsters that don't know it.
