Bigendersize is a static gender in the bigender system in which one has two distinct, separate genders rather than any sort of mix and one gender outweighs the other.
An example of a bigendersize individual would be someone who is solely man and non-binary. This individual would be distinctly both rather than a mix of the two and would be more man than non-binary. They can choose to say that their two genders are man and deminonbinary or say they’re man and non-binary.
The flag was created by the coiner in the coining post, on the same date. The red represents the one gender that is larger than the other. The grays represent the static gender. The black represents being both genders separately.
