Brickhillgender, also known as BHgender, is when one's gender is built in layers, each layer being strong and sturdy. These layers could be multiple xenogenders, non-binary genders, etc. It's up to interpretation.
The term Brickhillgender was coined by wiki user Cinnamonrollie on February 14th, 2021 as a gender counterpart to brickhillsexual.
The flag was created the same day the term was coined. The meanings are as follows: Pink represents feminine genders, blue represents masculine genders, yellow represents non-binary genders, purple represents xenogenders, and white represents the possibility for more. The colors are all in pastel to represent the softer genders.
