Ok, so back in August I saw an entry in a public nethack highscores file that listed "choked on an attempt at self-fellatio" as the reason of death. I've asked a question about this here, which was then promptly deleted for being too adult-themed.
I've also received a nice email by Juan Manuel about this in which he linked to the meta discussion about adult-themed gaming. Since nethack isn't an adult-themed game by any stretch, I'm not sure whether that discussion applies. I do see his point though - the question was kind of adult-themedish.
Juan also suggested I ask a question on meta if I disagree with his decision. But since I didn't feel too strongly about it at the time, I just left it alone.
However I've since found the answer to my question - it isn't anything dirty and I think it's actually quite clever. I figure it's a shame that I can't post this answer for posterity.
So now I'm taking Juan up on his offer after all and open this up for discussion: Should the question have been deleted?
