Short answer: No. In Jainism, the principle of ahimsa (non-violence) extends to speech. Making fun of someone’s mother in a way that insults or hurts her dignity is contrary to non-violence, compassion, and respectful speech.

What to do instead:

• Keep humor light and harmless, avoiding personal attacks or demeaning jokes.
• If you want to share a joke, choose topics that don’t target people’s identities or families.
• Practice right speech: truth, kindness, and usefulness in what you say.

Both Digambara and Śvetāmbara traditions emphasize speaking with care and avoiding harm to others, so such jokes would generally be considered inappropriate within Jain ethics.
