in gay slang, a fag hag is a woman – usually a heterosexual, cisgender woman – who surrounds themselves with gay and bisexual men, such as having friends that are mostly or exclusively men who have sex with men, or spends their time in gay clubs, gay venues and is heavily involved in gay culture.

The term is problematic because it is seen by some as being misogynistic or that it suggests that there is something wrong with heterosexual people involving themselves in the gay scene, thus being exclusionary and stigmatising, and is objected by some for its assumption that such women seek out homosexual and bisexual men as substitutes for romantic partners.

As such, the term fag hag has been used in an insulting sense. However, some women have embraced the term, and it has also been used in an endearing way to describe straight women who involve themselves in gay culture and the scene.
