What does gender-fluid mean?

Gender-fluid refers to a nonbinary gender identity or gender expression that’s not fixed and is capable of changing over time.

Where did the term gender-fluid come from?

The term gender-fluid emerges in the 1980s, coming into use alongside somewhat adjacent terms: transgender evidenced in the 1970s, and genderqueer in the 1990s.

The term gender-fluid spread with the understanding that gender was not binary (only and always male or female) and not necessarily tied to physical sex characteristics. Philosopher Judith Butler helped advance this thinking and is often credited with popularizing the idea in the 1980-90s that gender is socially constructed. Writers like Sandy Stone were also influential. In 1987, she penned The Empire Strikes Back: A Posttranssexual Manifesto, an essay discussing trans identity and the need for an assertion of such identities in a cisgender-centric world.

The mid-1990s into the early 2000s was when trans identities, like gender-fluid identities, were finding their footing. Online communities, because of their private yet communal nature, were safe places for LGBTQ people and are where many first encountered the word gender-fluid.

The late 2000s and the 2010s were when the term truly began to be noticed, venturing somewhat out of online forums, especially in academic literature. This was also the time when millennials, of whom 12% identify as non-cisgender, were beginning to come of age. By 2011, gender-fluid had 37,000 hits on Google. In 2018, this increased to a staggering 2.3 million.

Social media has begun to catch up with the changing understanding, and growing acceptance, of nonbinary gender. In 2014, Gender Fluid and genderfluid were added as gender options to Facebook and OKCupid, respectively.

A person isn’t considered gender-fluid just because they like to wear typically masculine clothing one day and feminine clothing the next day—that is considered a form of gender expression. To be gender-fluid is chiefly a question of internal personal identity, and is therefore a psychological phenomenon.

How to use the term gender-fluid

Gender-fluid is a label of self-identification, and people who are gender-fluid may also identify as transgender or nonbinary or genderqueer.  A person’s gender can favor genders outside the binary too, like agender. Everyone’s experience with their own gender is unique, and because of this there are so many ways to be, and to express being, gender-fluid.

Some who identify as gender-fluid might experience gender dysphoria, which is a psychological feeling of discomfort based on people’s perception of their gender resulting from the misalignment between that and how they identify.

Some celebrities have even been known to identify as gender-fluid. For example, Ruby Rose in 2014 and Miley Cyrus in 2015 both claimed the term as an identity, stating that they don’t feel like either traditional gender. Loki, the shape-shifting antihero of the Marvel universe, is also portrayed as gender-fluid in a series of 2019 novels.

People may also use gender-fluid somewhat erroneously to refer to something that can apply to either of the binary genders. For example, a color like yellow could be gender-fluid, since it doesn’t conflict with traditional gender stereotypes (e.g., blue for boys, pink for girls).

Gender-fluid people, unfortunately, are often the target of bigotry and transphobia, with objectors sometimes using gender-fluid as a slur. Gender-fluid is also the subject of some mockery given the range of terms for gender expression and identification that have become available since the 1970s.

More examples of gender-fluid:

“Had I seen people like me – or Ruby Rose, who appears in Orange Is The New Black and identifies as gender fluid – earlier in my life, I would have had context for my feelings.”
—Tyler Ford, The Guardian, August 2015
