Qirl is a gender identity for black transgendernonbinary people. A self-identified qirl called vmerli described it as "A black identity similar to girl but separate from the white/western gender binary." Vmerli drew inspiration for the term from African American Vernacular English (AAVE). It is similar to the boi identity. Transgender people who use the term to refer to themselves use pronouns of any kind, regardless of gender. People who tend to use 'qirl' as a gender identity in itself are usually nonbinary girls or feminine.
Feminine nonbinary people who aren't black shouldn't call themselves qirls, and instead should think about other identity labels for themselves, such as demigirl or femme.
