Bigender

Bigender is a gender identity on the LGBT+ spectrum. A bigender individual often switches between strictly two genders or gender identities, although it's not always male and female. Bigender people can identify as two genders at the same time or at different times, too, and whether they switch genders regularly or not depends on the person.

The Flag
The bigender pride flag has two pink lines on the top (dark and light pink), two pale purple lines between a white one, and two blue lines on the bottom (light and dark). The pink lines represent femininity, the purple lines represent identifying with no genders, the blue lines represent masculinity, and the white line's meaning is unknown, although it could be used to represent allies or people with an undefined gender identity.

Terminology
The term bigender was first used in the 1970s.
