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.
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.
No. Given the rather odd and not - so - common naming, it's highly unlikely to be a popular fanfic. Popular fanfics usually have more accessible and mainstream - friendly names.
Well, it could imply that in a Naruto - related fan - created story (fanfic), Naruto somehow causes destruction within a situation that is very difficult or 'tight' in the context of the fanfic's plot. But without more context, it's really hard to be specific.
