A cisgender, heterosexual woman who fetishises gay
men. The term "girlfag" is a self proclaimed label, and is an offensive use of the homophobic slur "fag" as they have no right whatsoever to reclaim the slur, since they are heterosexual. They also seem to enjoy using the word "queer", which is also a slur they have no right to reclaim.
Girlfags are incredibly homophobic and transphobic, as they see gay
men as
nothing more than an object to fetishize, they compare themselves to gay trans
men which spreads false information, and they try to
get themselves into LGBT spaces and call themselves "queer" for their fetish, which is dangerous when accepted as there are a large portion of girlfags who
aim to sexually abuse and even attempt to rape gay
men.
The male version of Girlfags are Guydykes.
There seems to be a considerable quantity of girlfags using the judging section of Urban
Dictionary, as they keep refusing this definition in favour of the other, sugarcoated and bullshit-filled definitions that are already there.
Girlfag: Omg I'm so attracted to gay
men! I'm so queer! I'm like a gay trans man!
Gay guy: Uh... no. You're straight and cisgender and have a fetish for gay men. You're not "queer", you have no right to say that word, and you're
nothing like a gay trans man.
Girlfag: OMG STOP INVALIDATING MY IDENTITY YOU QUEERPHOBIC PIECE OF
SHIT AND IF YOU WON'T FUCK ME YOU'RE SOOOO FUCKING SEXIST OMG
