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.
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.
There are also fanfics that explore the backstories of other minor characters in the Naruto universe, like how they got into the ninja academy and their dreams before becoming full - fledged ninjas. This kind of fanfic gives more depth to the overall Naruto world.
Using such a title violates the norms of good taste and respect in the fan community. Fanfic is meant to be a form of creative expression that is inclusive and family - friendly, not containing such offensive elements.
We could rewrite it as 'Harry ruins a certain fan - created story'. This way, we remove the vulgar and inappropriate language and focus on the more general idea of Harry having a negative impact on a fanfic.
