I've looked at the conversation in general and, without knowing full context (your history with one another), I would agree both of you are being decently nasty towards one another with personal insults and condescension. You insult him ("Sanji wankers") as much as he does you.
I don't know the consistency with which this becomes an issue, but this singular incident is just two kids bickering, a minor ass issue that we do not generally hand out rule violations for. If it is an established trend, I will leave a general premonition for both of you: we have, in the past, topic banned individuals who cannot play nice with one another.
