I was surprised to see someone being pulled up over the use of the word 'twat' yesterday. If said person had used the word against an individual, as in 'you are a twat', then I could see why that might be out of order, but he was simply using it in the way you might say something was 'a pain in the arse', or a 'a right balls-ache'. Even more weirdly, when someone pointed out the 'three words daily' thread for comparison, he was told by the moderator that twd is a 'light-hearted' thread where, by implication, such language was OK.

Now, I seldom use bad language, being the polite person I am, but it would be good to know which words are or are not OK. pfm has a 'swear filter', where the forum software censors certain words, leaving asterisks in place of letters, so the job is done for you. But what's OK on AoS language-wise?
