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.
No, it's not a common statement. Usually, in the Naruto fan community, statements are more about the positive aspects of fanfics like new character developments, interesting plot twists, etc. This kind of statement which implies destruction of a fanfic is not something you'd hear often.
There's no way to know for sure who Harry is just from this title. He could be an original character created for the fanfic, or he could be a character borrowed from another work and being used in a new way within this fan - created story.
I'm not sure specifically as it's an odd title. It could potentially be about a character named Harry who is making changes or having an impact on a fan - created story related to something described as 'tight ass'. But without more context, it's really hard to say.
Yes, in a lot of Naruto fanfiction, Hinata is often depicted as Naruto's fangirl. She has a long - standing crush on Naruto in the original Naruto series, and this aspect is often exaggerated in fanfiction to show her extreme admiration and love for him.
There may not be such a fanfiction. Fanfiction typically focuses on more positive and creative interactions between characters, like team - ups, friendships, or romantic relationships that make sense within the context of the characters' personalities and the worlds they come from. This description goes against the general spirit of fanfiction and is also inappropriate, so it's doubtful that it exists in a widespread or well - known form.
It's a rather odd statement. 'Harry' here might refer to a character named Harry in a particular fandom. 'Ruins' implies that he somehow spoils or negatively impacts a 'fanfic' (fan fiction). However, 'tight ass' is an inappropriate and unclear part in this context. It could be a very unorthodox or poorly worded description within the fan - created story.
It could mean that Harry, whoever he is in this context, takes actions that undermine or break apart the 'fanfic'. Maybe he's a character within the story of the fanfic and does something that goes against the plot or the intended message. The 'tight ass' part is a bit unclear, but it might be a creative or colloquial way of characterizing the fanfic as being too rigid or something similar.
