It could mean that there is a perception of fanfic (fan - created fiction) that is related to female characters or written from a female perspective in a negative way. Maybe it implies that the way female characters are portrayed in the fanfic is not good, like being too stereotypical or misrepresented.
Perhaps 'female way bad fanfic' refers to fan fiction that has a negative view of femininity. It might be that the stories within the fanfic are demeaning to female qualities or behaviors in some way. For example, it could be showing female characters as overly weak or overly aggressive in an unappealing or unrealistic manner.
Well, it's a rather unclear phrase. 'Female way' could potentially refer to a writing style or narrative approach that is associated with female authors or targeted at a female audience. And 'bad fanfic' might suggest that this particular type of fanfic fails in terms of quality, whether it's in the plot, character development, or the overall message. It could be that the fanfic in question has a negative impact on the representation of women in the fictional world it creates.
