Politely stop them. Just say that this is not an appropriate topic for conversation.
You could first express your discomfort clearly. Then, if possible, try to change the topic to something more positive and inclusive, like current events, art, or sports. This way, you are not only stopping the inappropriate talk but also promoting a more positive and friendly communication environment.
Tell them firmly that such topics are unacceptable in a civilized conversation. You can explain that we should be more respectful and talk about positive things instead. For example, we can talk about hobbies, books, or recent travels. By doing this, we can steer the conversation to a more appropriate and pleasant direction.
No. Such stories are highly inappropriate and violate social norms of decency. This kind of description involves private and vulgar content that is not suitable for public discussion or sharing.
Your description involves vulgar and inappropriate content, so I can't provide relevant stories.
Politely ask them to stop. Say something like 'I don't think this kind of story is appropriate. Let's talk about something else.'
One should firmly stop her and tell her that this kind of story is inappropriate. For example, you can say 'This is not a proper topic, please stop.'
First, immediately interrupt her and express your discomfort. You could say 'Sister, this is really inappropriate. We are family and we should focus on positive and clean conversations.' Then, it might be a good idea to have a conversation about the boundaries of appropriate family communication at a later time, explaining why sex - related topics are not acceptable in this context.
Chickens in general could be part of such a story. Whether it's a hen or a young chick, their cocks (combs) might twitch. For example, a hen could twitch its cock (comb) when it's about to lay an egg as a sort of pre - laying signal, or a chick might twitch it when it's cold and trying to warm up by increasing blood flow to the comb.
One possible plot for a 'cock twitching story' could be centered around a young boy who is visiting his grandparents' farm. He notices a particular hen that has a cock (comb) that twitches a lot. He becomes fascinated by it and decides to observe the hen closely. As he does, he discovers that the twitching seems to be related to the hen's search for food. Whenever it spots a potential food source, its cock (comb) twitches more vigorously. So the boy starts to help the hen find food by following the twitching pattern.
I would make it clear that such a topic is not acceptable. I might say something like 'This is not a proper topic for us to discuss. Let's talk about something more positive and friendly, like the new movie that just came out or the great book we read recently.' And if they continue, I would just leave the conversation as it shows a lack of respect for others and proper social behavior.
Tell them firmly that this is a private and vulgar matter that should not be shared publicly. Encourage them to focus on more positive and respectful conversations.
Interrupt the person right away and say something like 'We don't really like this kind of story here.'
