Earlier quoted context omitted.
The other day, I tried an underhanded trick in a board game and won, and my friend said something along the lines of "You are a real piece of shit." She was really frustrated that I'd managed to trick her like that, but I knew there wasn't any real hatred underneath and I took it as a compliment. Would you harass my friend for our friendly banter, since the fact that we are both 100% OK with the conversation is irrel…
Yep. I would like to think I would be respectful in informing her I found her comment impolite, just like I would tell someone who said something sexist that their comment is unacceptable.
If someone told me to mind my language over a casual board game, I'd tell them to fuck off. A friendly jibe is just a friendly jibe, regardless of whether it had the word 'shit' in it or not. Words matter, but far less than intent does - and the intent of telling someone to clean up their act in a casual setting is that they're patronising you.
