Favper- is a prefix that can be added onto any gender. It means that someone feels a certain gender only when around someone's favorite person (also known as an FP).[1] For example, someone who identifies as a favperman will only identify with being a man when around their FP. Because of this connection, this term is exclusive to individuals with borderline personality disorder, BPD for short. [2]
Both favper- and borderix genders are experiences when one is away from one's favourite person. The difference is that the borderix gender doesn't feel as intense and almost non-existent, whereas a favper- individual does not feel said gender at all.
For example, one may be primarily Genderfaun (fluid but never feminine), however when around one's FP the individual may feel more Non-Binary or even Feminine - translating to Favperenby and/or Favperfem.
Etymology
"Favper" is a portmanteau of "favorite" and "person". Favorite person is a term exclusive to those with borderline personality disorder.
History
The term was coined by the Discord user Astronomical Chaos#8607 (handle may be outdated) - specifically by their system member Loki (part of the Astronomical Chaos Cluster) who wanted to describe his experience with gender while being with his FP.
