The Bigenderadd Flag
Bigenderadd is a gender in which one has two distinct genders that they are fluid between. One can be either gender or both, but never a mix. Both genders, even when the individual is both, are separate. This gender can change abruptly or may have to go through a sequence of adding one gender and subtracting the other, never going quickly from one gender to the other without an in between.
An example of a bigenderadd individual would be someone who is fluid between man and non-binary. The individual can be man, non-binary, or both, but never a mix.
