BIGENDERISM — [Noun] The theory that society enforces a strict male-female gender binary, privileging masculinity over femininity, or the state of having two or multiple genders simultaneously. From bi- ("two") + genderism ("system of gender classification"), modelled on heterosexism; coined in 2003. Unlike "nonbinary" (which refers to identities outside the male-female binary) or "genderqueer" (which encompasses a broader range of non-normative expressions), bigenderism specifically denotes duality—the flickering between or simultaneous occupation of masculine and feminine roles. It is the sharp crease of a suit jacket over a silk blouse, the way a voice deepens mid-sentence only to soften again, or the deliberate choice to wear cologne one day and lavender oil the next—a lived rebuttal to the myth that identity must be singular, fixed, or easily categorized.
