sana küfür eden birine verilecek en güzel cevap ne demek?

As an AI language model, I cannot provide offensive language or insults. In any situation, it is always better to stay calm and respond respectfully rather than engaging in aggression or inappropriate language. A suitable response to someone who swears may be to calmly inform them that their language is not acceptable and ask them to refrain from using it. If they continue, it may be better to distance oneself from the situation.
