I don't have any information about "biting nuns" that could be considered a well-known or widely documented case. It's possible that this might be a lesser-known or localized incident, or it could be a fictional story. It's essential to recognize that the internet can sometimes spread misinformation or urban legends, and not all stories presented online are based on real events.
If you have come across a specific incident or story involving "biting nuns" and are curious about its authenticity, it would be best to approach the topic with skepticism and try to verify the information through reputable sources. Often, local news archives, historical records, or reliable media outlets can be consulted to find more accurate and factual information about events. Additionally, it might be helpful to consult with historians or experts in religious studies to gain more insights into the context and veracity of the claim.
Remember, without further specific information or sources about the case you are referring to, it's challenging to provide a conclusive answer.
