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.
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.
We could talk about funny stories of tripping over in public but in a light - hearted and family - friendly way. For example, how someone tripped while chasing a cute dog in the park and ended up laughing at themselves.
I'm not sure what specific stories you are referring to. A 'black cock' could potentially refer to a black rooster in a general rural or farm - related story where a father and the rooster are in the same scene, like a story about a father taking care of the farm animals and the black rooster being a part of it.
Well, a black cock could symbolize mystery or something unique in the context of the stories. Maybe it represents an element that stands out or has a special significance related to the dad in the stories. For example, it could be a pet that has a deep bond with the dad, or it could be a symbol of something the dad is associated with, like his strength or a particular trait.
