Was having a get together today with a group of five friends. We now live all over the place but have known each other for over 20 years and are more like sisters in a lot of ways and very close even though we don't see each other that often. I was really looking forward to seeing them all.
We are always very silly and jokey with each other and take the piss quite a bit. Lunch came and we started talking about wine and having a conversation about the type we like and one of them started saying something along the lines of "I like it quite dry, not very sweet..." Just a few banal comments. I said in a jokey way: "very interesting!" (Bear in mind we had all been joking and saying silly things to each other well before this) and she just snapped at me and across the table said: "That's really not nice, don't, stop being a knob." She was being really serious. It reminded me of an angry parent chastising a child (without the word "knob" of course) and the way she said it was as if I was being really nasty and vindictive which I honestly would never ever mean to be.
I was really shocked and embarrassed and think only one other friend heard and we just kind of ignored it and carried on talking about something else. My stomach had turned because I felt so awful about it with a friend I have never had a problem with and she seemed so pissed off. I just carried on conversation with a couple of the others then towards the end of the night chatted politely to this friend about something but felt upset about how she had spoken to me. I couldn't tell if there was weirdness between us or not I thought maybe a bit.
Was what I said really so rude and awful? I know it's hard without context but we are always joking around.
