Is it permissible to joke by saying "son of a bh" or "Jew" with the mere intention of laughter?

A Muslim must accustom their tongue to good speech and avoid offensive terms like "son of a haram" (walad al-haram). This phrase is considered an innuendo of slander, but in common parlance today, it does not necessitate the prescribed punishment (hadd) because it is used to denote disparagement and blame, not explicit slander. Jurists believe that terms of slander follow customary usage. As for saying "O Jew" to a Muslim, it is a great abomination and a severe warning, and its speaker should be disciplined. It should also be noted that a fiancée is a stranger to her fiancé, and it is not permissible for him to be alone with her or for her to uncover herself to him except to the extent that allows for acquaintance.
