A woman who is very attracted to gay/bi/trans men. She may (or may not) also feel she is (fully or partly) a "gay man in a woman's body". Girlfags identify primarily as queer, and are often attracted to more types of people than just gay/bi/trans men.

An assigned-male-at-birth femme person who identifies at least somewhat as a girl and at least somewhat as a fag.

The word "girlfag" was too good to waste on cis girls fetishizing gay men, so the femmes decided to steal it.
"So like, are you a trans girl, a femboy, or what?"

"Honey, I'm just a girlfag."

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
