There are a few reasons why talking about poop may be considered weird or taboo in some cultures:
Social norms: In many cultures, bodily functions like using the bathroom are considered private matters that are not discussed openly in polite company. Breaking these norms can make people feel uncomfortable or embarrassed.
Disgust factor: Poop is generally considered to be unpleasant and smelly, which can elicit feelings of disgust or revulsion in some people.
Health and hygiene concerns: Talking about poop can also be associated with discussions of disease and cleanliness, which some people may find uncomfortable.
However, it's important to note that in other cultures or situations, talking about poop may not be considered strange at all. In some medical or caregiving contexts, for example, discussing bowel movements can be an important part of monitoring a patient's health. Ultimately, whether or not it's "weird" to talk about poop depends on the social and cultural context
