The Prophet ﷺ was not one who would abuse (others) or say obscene words, or curse (others), and if he wanted to admonish anyone of us, he used to say: "What is wrong with him, his forehead be dusted!" (Using translation from Bukhārī 6031)
لَمْ يَكُنْ رَسُولُ اللهِ ﷺ سَبَّابًا وَلَا لَعَّانًا وَلَا فَحَّاشًا كَانَ يَقُولُ لِأَحَدِنَا عِنْدَ الْمُعَاتَبَةِ مَا لَهُ تَرِبَ جَبِينُهُ
