It might also be a story within a specific cultural or regional context where 'big cock' has a different meaning. In some cultures, certain animals are symbols of good luck or strength. So perhaps in this story, the 'big cock' represents such a symbol and the person loves the story associated with it and what it represents in their cultural heritage.
It could mean stories about straight people who are very confident or have a big - hearted nature. The 'big cock' part might be a metaphorical way to describe their boldness or strength of character.
One possible interpretation could be that it's a story about a person who has a pet or something that they 'keep' and there is some sort of strange or humorous situation related to it that is being described in a rather unorthodox way.
Let's say there is an old man who lives alone on a farm. He has a few ordinary chickens. One day, a big cock shows up on his farm. This big cock is not like the others. It has a strange mark on its head. At first, the old man is a bit scared but then he realizes that this big cock is very intelligent. It starts to do things like find hidden treasures on the farm (like old coins or lost tools). The big cock's actions surprise the old man and bring some newfound joy and prosperity to his lonely life.
One possible theme could be competition if 'taking 1st' implies being the first in a race or a contest. Another might be growth, like if the 'big cock' represents something that has grown large and the story is about the process of dealing with it for the first time.
One possible interpretation could be that it's a story centered around a girl's big black heels. Maybe it's about the first time she wore them and how she felt. Another could be that the 'big black' refers to the appearance of the heels, and the story is about how they are unique in a way that is associated with girls.
Well, '50 50 true story' could mean a story in which there is an equal chance or probability of two outcomes. For instance, in a game where the odds of winning or losing are the same, that's a 50 - 50 situation. And since it's a 'true story', it might be someone's experience with such a situation in real life. Another interpretation could be related to a physical division. Say, a piece of land is divided equally into two parts between two owners, which is also a 50 - 50 scenario and could be the basis of this 'true story'.
One possible interpretation could be that there was an object that was big and black on someone's back while a white boy was at a urinal. It could be as simple as that, like someone had a large black bag on their back in a restroom situation.
It could also be that the 'cock' is being used in a more symbolic way. For instance, it could represent something unexpected or out of place that the mother comes across. However, more often than not, if we take it literally, it's probably about a mother seeing an actual male chicken. For example, she might be visiting a poultry farm and has an interesting encounter with a cock there.
It might be a fictional story set in a world where there are unique rules or cultures. For example, the 'hige cock' could be a group or a person with a certain status, and the 'wofe swap' is an event that goes against the normal social norms in that fictional world. But again, this is all just speculation due to the unclear nature of the phrase.
It's also possible that 'black cock' is used in a more metaphorical sense. Maybe it represents a difficult or unexpected element that the social worker has to deal with. Just like a black cock might stand out or be a bit of an oddity, it could be that there is an aspect of the social worker's job that is out of the ordinary and the 'black cock' is a way to represent that in the story. However, without more information, all these are just guesses.
