If you want to RP correctly, well i guess you should use some kind of flaming and such. But if the player itself feels insulted, it get's too far.
I would advise to not do it, seeing as a random boy could fly by and see all the chatter, then decide to report this for flaming/insult and we have a big mess.
Also, perhaps you could PM the player that does this that he should please use another kind of language because it's hitting you yourself.
In a brilliant tactical movement, i charged backwards.
