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.
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.
Well, 'harry' here might refer to a character named Harry. 'Destroys' could imply that he has a negative impact on or undermines the 'tight ass fanfic'. However, without more context, it's hard to be certain. Maybe in this fanfic, Harry's actions go against the ideas or plotlines that were set up in a rather forceful way.
I don't think it is. Fandom statements usually revolve around praising the fanfic, discussing characters' development, or sharing favorite parts. This phrase sounds more like a very specific and rather negative reaction to a fanfic that is not commonly heard in general fandom chatter. It might be something used in a very niche or private discussion within a small part of a fandom.
I'm not sure if it's a common statement in any specific fandom. It seems rather unusual and specific. It could be something unique to a small group of fans or even just a one - off comment made by someone. There are so many different fandoms out there, and this doesn't seem like a widespread or typical statement among them.
It could mean that Percy, perhaps a character or a person, is ruining or disrupting a very good or well - constructed fanfic. Maybe Percy has some sort of action or behavior that goes against the plot, characters, or themes of the fanfic, thus 'destroying' it in a sense.
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.
