It could also be a case of mistaken identity. A new character in the village, who has a grudge against someone who looks like Naruto from the back, pinches him hard. Naruto is initially confused and then angry. He has to then resolve the situation by explaining that he's not the person this new character has a problem with, and in the process, he befriends the new character who realizes their mistake.
One possible plot could be that it's a prank gone wrong. Maybe one of his friends, like Kiba, was trying to play a silly joke on Naruto during a training session. Naruto then overreacts and it leads to a comical chase around the training ground as he tries to get revenge.
It could be a jealous rival from another village. This rival sees Naruto as a threat and decides to play a mean prank on him by giving him a harsh pinch on the ass. This could then lead to a rivalry - based story where Naruto has to prove himself against this rival not just in combat but also in terms of dignity.
Well, it's really hard to say exactly what the plot would be with such a strange title. Maybe it could be about Naruto getting into some really wacky adventure where he discovers something odd about himself, like a new power related to that strange phrase. But this is just pure speculation.
Well, it could be about Naruto using some kind of special jutsu to reshape someone's rear end in a comical or perhaps even strategic way in the context of the fan - created story.
A 'naruto fat ass fanfic' might involve Naruto accidentally being hit by a strange jutsu that affects his body shape, specifically his posterior. His friends could initially be shocked but then they all try to find a way to reverse it. It could be full of humorous interactions between Naruto and his friends like Sasuke making sarcastic remarks and Sakura trying to find a medical solution.
In the fanfic, it could start with a build - up of tension between Naruto and Sasuke. Naruto has been training hard and has reached a new level of power. Sasuke, on the other hand, might be underestimating Naruto. When they finally clash, Naruto's sheer determination and his unique Uzumaki chakra, along with his mastery over the Nine - Tails' power, allow him to dominate the fight and kick Sasuke's ass. This could also be a way for Naruto to try and bring Sasuke back to the village, by showing him that he can't always have his way and that they are stronger together.
I'm sorry, but writing or promoting fanfics with inappropriate content is not acceptable. We should focus on positive and respectful stories in the Naruto universe, such as Naruto's journey to become a great ninja, his friendships, and his battles against powerful foes.
Well, the plot could start with Itachi realizing that Naruto is the key to the future of Konoha and the ninja world. So, he gives Naruto his Sharingan. Naruto then has to deal with the new power. He might start having visions related to Itachi's past, which could help him understand the Uchiha - Senju conflict better. And this new knowledge could influence his decisions in future battles and political situations in the ninja world.
Well, one plot twist could be that Naruto is actually using a new, secret jutsu that he's been developing in secret. This jutsu gives him an edge over Sasuke that Sasuke didn't expect. Another could be that Sasuke is actually holding back for some reason, like he doesn't really want to fight Naruto but Naruto misinterprets it as Sasuke being cocky and goes all out.
Writing or promoting fanfics with inappropriate and disrespectful content like this is not acceptable in the Naruto fandom. The Naruto series is about friendship, growth, and ninja adventures, not such vulgar scenarios.
A plot for this type of fanfic could revolve around Naruto's inner turmoil. He could be constantly haunted by the question of why his parents neglected him. This could lead him to make some bad decisions, like getting involved with the wrong people. However, through a series of events, he starts to realize that he can create his own family and support system. He then begins to build a new life for himself, one that is not defined by his parents' neglect but by his own strength and the relationships he chooses to cultivate.
