AcronymforGuy In Real Life.
Based on the belief that There Are No Girls on the Internet. Some forums, particularly male-dominated ones, will be the victim of a special breed of Troll who will pretend to be a girl just to rile up the boy nerds in the community. They display obvious Cam Whore traits and may even steal photos of attractive girls off MySpace or Facebook and claim that they are them.
In other cases they may copy photos of their sisters/daughters/nieces/female cousins off photo cd's or the like, especially if said females are of, or close to, the age of the online persona.
Female forum goers have a tendency to get a lot more attention, just by being girls, so many male attention whores use this to their advantage so that they get the attention they crave. They will play and flirt with the male members who may become tickled pink that a girl is talking to them this way. Sad, but true.
Will ultimately lead to a reveal where they show their true colors as blokes and laugh at the incensed regulars. Or, a Regular will wise up to his shenanigans and unmask him causing everyone to point and laugh at him as he slinks away with his tail between his legs. Could also be a practical joke played by a Regular to which everyone will simply have a good laugh. Most cases tend to end in the second case, which brings up the question of why such trolls even bother doing it since the risk of being exposed far outweighs the potential gain.
Naturally, any mention of online dating in the "Old Media" will end this way, whether played for laughs or for drama, because everyone knows the internet is solely the domain of perverts.
If you think this is bad, though, be grateful you're not dealing with a Mailer Daemon.
Note that not everyone who's biologically male who presents as female online is trolling; see Cross Player, Transsexual. Leads to actual women on the Internet using male or neuter user names and fudging personal details specifically to avoid this trope.
This is often inverted on many female dominated forums, such as LiveJournal, where the default identity of new posters is assumed is female, and a guy, who acts normally but doesn't explicitly mention he is a guy, can go for a long time without anyone asking or realising, leading to "You're a guy??" moments 6 months down the track.

.hack//SIGN completely inverts this as being the major "twist" of the series. As well as it being a case of amnesia (sort of).
Well, it's not really played as a twist—it's brought up early on, then rejected but only by the character in question saying "Of course I'm not a girl!" So when it's revealed that the initial theory was right all along it's not very surprising.
A better example is Saburou from .hack//Roots. She actively claims to be female and states that she simply acts like a boy because many boys act like girls in the game when called out on it due to her male name and male way of speech. The fact that she's on this page means of course, she is male in the real world. It's even pointed out on her character design for Link where her head band is adorned with the male symbol.

This happens to Kirito in the fifth light novel – officially, his VR equipment is supposed to scan the user's brainwaves to correctly determine gender, however Kirito apparently counts as "close enough" to female that he was granted the rare effeminate male avatar but is mistaken for a female anyway. He is understandably annoyed by this.
In Ultimate X-Men Beast gets into a relationship with a girl on a chatroom...who is actually the Blob, one of Magneto's henchmen, pretending to be a girl for kicks (a mutant genius supermodel, no less). Then Henry accidentally blabs about how Xavier brainwashed Magneto. Oops.

This is the idea behind Frogg Marlowe's song "Ain't No Women":
Interestingly enough, even though women make up about one-third of the playerbase, the number of male and female characters in-game is almost exactly fifty-fifty. The reason for this is that approximately one-third of male players use female avatars, whereas only ten percent of female players use male avatars.
In the comedy column "Ask A Faction Leader," someone asks Chronormu (whose model in-game is a female gnome) about her masculine name.

Played straight and subverted in one of its oldest forms. On the Original TinyMUD, back in 1989 there were only male characters. Then within about 3 weeks, a bunch of women showed up. about half of them was a single, actual teenage girl, Claire. Almost all the rest were played by guys.

In Megatokyo, this is used - in a rather twisted fashion - during a flashback. Piro plays an MMO with a male character, starts chatting with him outside the game, and eventually starts to wonder if 'he' isn't actually a girl... eventually, he seizes on an opportunity to ask him for a picture. He gets it, and sure enough, 'he' is a cute girl, whom he starts to fall in love with. Then she dumps him by revealing that she's actually a guy, the picture was fake, and she was just playing with him for kicks. The twist? The picture was real, and she really IS a girl. Exactly why she pretended to be a G.I.R.L. is, as yet, unknown, but Piro is still pissed at her for pulling that stunt...
Also, Piro himself is cross playing, and out of the flashbacks, Miho tells him that she sometimes believed he was really a girl.
