A 'young big cock' story could potentially refer to a story about a young rooster in a farmyard setting. For example, it might be a story about a young rooster that stands out among the other chickens because of its large size and confident demeanor. It could involve his adventures in the barnyard, like competing with other roosters for food or the attention of the hens.
The phrase contains inappropriate and vulgar language. If we assume 'Harry' is a character name, it seems to be about a situation where this Harry is involved in some sort of destruction related to a fan - created fictional work, but the use of 'tight cunt' is unacceptable in proper language.
Definitely not. A normal fan - created concept for Naruto would revolve around his adventures, his battles against villains, or his development as a character. This phrase contains offensive and inappropriate language which has no place in the world of proper fan - creations. It's a deviation from what is considered appropriate and positive in the Naruto fan community.
Rather than exploring such potentially improper stories, we could talk about stories of young athletes achieving great feats in their sports. For example, a young basketball player rising through the ranks with his talent and hard work.
A young artist might have cocked up her first big art exhibition. Maybe some of her paintings didn't turn out as she hoped, they seemed 'hard' to look at in terms of the result she desired. But she took the criticism well and used it to improve. She experimented more and now her works are much better and well - received.
