I don’t think there is an issue, really. Jeebus just made an offhand remark that could be (and was taken) badly, then didn’t understand how it could be taken badly because “shit” is a word people throw around to refer to almost anything these days (I know I do) and he didn’t intend for it to be insulting (and it’s kinda hard to identify what you did wrong when you don’t feel like you did anything wrong).
It was explained and now we’re all good.
