I'm not sure specifically as there could be many interpretations. It might be a fan - made story where Naruto has some sort of relationship or connection with Tenten. Maybe it involves Naruto having something that belongs to Tenten in the context of the fan - created plot.
Well, 'naruto owns tenten fanfic' could potentially be about Naruto coming into possession of something related to Tenten in a fictional scenario created by fans. It could be an item, a power, or even a symbolic 'ownership' like Naruto being in charge of protecting something that Tenten values. Without reading the actual fanfic, it's hard to say for sure.
