Bigenderscale is a gender in the bigender system in which one has two distinct genders that that they are fluid between. One can be either gender or a mix of the two genders, but never fully both. This gender can change abruptly or can work like a sliding scale, gradually transitioning from one gender to the next.
An example of a bigenderscale individual would be someone who is fluid between man and non-binary. The individual could be man, non-binary, or a mix of the two, but never both fully non-binary and man.
The flag was created by the coiner in the coining post. The blue and red represent the different genders that one is fluid between. The colors in between represent a mix of the two.
