There’s actually no rule against it, as long as people don’t go overboard. An occasional fuck or shit may not be out of line, while cursing like a drunken sailor in an inappropriate thread may be.
This is the kind of bleep that gets right up my bleeping bleep! You most bleep certainly are allowed to use bleeping curse words outside the bleeping Pit! This includes bleep, bleep, bleep, and especially bleep!
Don’t get me fucking started. For people who are afraid of swearing in a lighthearted way, I usually suggest the first 5 minutes of Four Wedding and a Funeral.
Mark Twain’s wife, Livy, was one of the few who did not appreciate her husband’s swearing, and he tried to keep watch on his tongue when she was close by; but one day something irritated him, and, thinking his wife could not hear, he launched into a torrent of red-hot profanity. When he entered his wife’s room a short time later, she coolly repeated word-for-word everything he had said.
“Livy,” he replied, astounded yet amused, “did it sound like that?”
“Of course it did,” she said, “only worse. I wanted you to hear just how it sounded.”
“Livy, it would pain me to think that when I swear it sounds like that. You got the words right, Livy, but you don’t know the tune.”
