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 CDs or the like, especially if said females are of or close to the age of the online persona.
For gaming otherwise, it's also common for video games featuring Character Customization and fancy clothes to have fashion enthusiasts creating and playing as opposite sex characters for aesthetical purpose. See Third-Person Seductress for more details.
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. In the case of online video games, particularly MMOs, this may be done with the intention of wringing free in-game money and/or rare items out of desperate, lonely male players who are only too happy to fork over such gifts as Favors for the Sexy.
Will ultimately lead to The 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. Note that not everyone who's biologically male and presents as female online is trolling; see Cross Player, Transgender.
If you think this is bad, though, be grateful you're not dealing with a Mailer Daemon.
In the end though, it all leads to actual women on the Internet using male or neutral user names and fudging personal details specifically to avoid this trope. Or to mess with people.
This is often inverted on many female dominated forums, such as LiveJournal, where the default identity of new posters is assumed to be 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 line.
Largely on the way to becoming a Discredited Trope, as the internet becoming more accessible in the 2000s and the rise of social media in the 2010s has made it much more likely that the person online is the actual gender they claim to be. Not to mention the rise of awareness of Transgender people from the 2010s as well, which has made accusing people of this trope much more likely that you'll be the one being ridiculed/called out for being transphobic.
- Referenced in Welcome to the N.H.K. where the beautiful Cat Girl healer in the RPG Episode turns out to be Satou's neighbor Yamazaki, out to teach him a lesson.
- As with many online games, .hack features many Cross Players.
- One of the major twists in .hack//SIGN is that Tsukasa is actually a girl in real life.
- 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. 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.
- Like any prepared troll, Izaya poses as a girl on the internet.
- Inverted by Celty, who poses as a guy. This is subverted in the Light Novels in that everyone in the chat had caught on to the fact that "Setton" was actually a girl since pretty much day one, and just didn't think enough of it to point it out until she mentioned a male roommate. Celty's not a terribly good liar.
- Discussed in vol 9 of the Light Novels between Bakyura and a new member, who's probably doing this, too: "she" is hinted to be Aoba. The kid's taking after Izaya fast...
- During one of the RPG Episode in Gintama, Gintoki choose to play as a female character. He do so because he know that they will need help to find the aliens who turned their body parts into screwdrivers, and think others players are more likely to help a girl. Kagura invert this by creating a burly male character.
- Flunk Punk Rumble (aka Yankee-kun to Megane-chan) inverts this for comedic effect.
- At the beginning of Nyotai-ka, protagonist Manaka Makoto is a nekama, a young man who, frustrated by his inability to attract the interest of women, masquerades as one on online dating sites for amusement. Hilarity Ensues when a goddess intervenes and suddenly, it's no longer just an act.
- In Ghost in the Shell 1.5 Batou is net-dating a hot young woman who's actually a ninety-year old man.
- A scene in episode 1 of Sword Art Online has a Mirror item reformatting all of the player's VR avatars to reflect their actual selves from real life. One quick scene shows a crowd of girls suddenly revealed to be mostly men using female avatars, and there is a minor Running Gag of a specific couple composed of a cute girl revealed to be a skinny man and a lean boy revealed to be a pudgy man who remain friends despite the shocking reveal, and later reunite after the end of the Incident in real life as friends.
Pudgy guy: You're a guy?
Guy in women's clothing: You lied about being seventeen?
- This happens to Kirito in the fifth light novel (where season 2 is adapted from) — 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 an extremely rare effeminate male avatar in Gun Gale Online. Consequently, a lot of people in-game mistake him for a girl. He is understandably annoyed by this, but when Sinon makes this mistake, he plays along with her misunderstanding because he's desperate and believes (correctly) that she's more likely to help him if she thinks he's a girl.
- This was, of course, parodied in Something Witty Entertainment's Sword Art Online Abridged: "So anyway, for all of you guys who wanted to play as girls, and you know who you are, I've got a surprise for you!"
Pudgy Guy: "You're not a girl!"Skinny Guy: "And you're not seventeen!"Pudgy Guy: "I'm okay with this!"Skinny Guy: "Me too!"Off-screen Guy: "LOVE KNOWS NO GENDER!"
- For the most part, though, this is defied, as some VRMMO games, like the aforementioned GGO, players are not allowed to play as the opposite gender, in order to avoid adverse side effects on players' mental health. Sinon would prefer to hide her status as a female player, but this system doesn't give her any choice.
- In Log Horizon, there is Tetra. Most of the namesake guild knows, but Naotsugu remains oblivious.
- Inverted with Akatsuki, who is a girl in real life but played as a male Assassin. After everyone gets trapped inside their own avatars, her first appearance is her begging Shiroe and Naotsugu to bring her a rare potion that will allow her to transform her avatar so she can be a girl again. Afterward, she swears her undying loyalty to Shiroe as a way of repaying him.
- The protagonist of My Dad's the Queen of All VTubers?! is a big fan of the #1 Virtual Celebrity of the setting... and then finds out that behind the scenes, his waifu is actually an old man. His own father, no less. Cringe Comedy ensues.

- Inverted with Schwein and Master, who play male characters in Legendary Age but are girls in real life.
- Nekohime admitted to Rusian after he confessed to her that despite being a female character, she is an older guy in real life. Subverted when its revealed that Nekohime actually is a woman, Hidekis teacher.
- The main character of Only Sense Online suffers from an involuntary case of this. In real life, he's an extreme example of Dude Looks Like a Lady, so when the console for the titular virtual reality game scanned his body, it assumed he was actually female. As a result, he was assigned a female avatar. In the game itself, everyone aside from his sisters, childhood friend, and class rep think that he's actually a girl, despite his protests.
- Referenced in Codename: Sailor V, when Minako, who was already going at the arcades when they still were men-only places, beat the record at a game and the previous record holder accused her of being a guy in a really convincing disguise - and demanded she took off "his" disguise, ending with a kick in the face.
- Recovery of an MMO Junkie has a double whammy, with protagonist Moriko Morioka joining the MMO Fruits de Mer as a male character named Hayashi and becoming good friends with the ludicrously adorable Lily, who's played by a male office worker named Yuta Sakurai. Hilarity (and romance) ensues. Their guildmaster Kanbe is aware of both their true genders, but keeps silent out of respect for their privacy.
- Their guildmate Himerelda is an example that everyone is aware of: she's a housewife playing a male elf but she doesn't adapt her behavior to her character's gender at all, making Himerelda come off as the guild's Gay Best Friend-slash-Cool Big Bro. Her husband is the guild's sub-leader Pokotaro and she'll occasionally log onto his account; she acts the same way as she does with Himerelda, which weirds out the rest of the guild since Pokotaro is a Big Fun type normally.
- In Monthly Girls' Nozaki-kun, Mayu's classmate creates a blog to post Mayu's racy drawings and names it Mayumayu's Blog. Mikoshiba finds the blog and assumes that it's a girl's blog and tries to contact "her"; but because he doesn't want to seem like a creep, he uses a female alias, Mamiko. Both guys then start contacting each other regularly, believing they're talking to a girl.
- 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.
- Also shows up in Runaways, where a guy cross-plays as Invisible Woman and The White Queen. Made rather obvious, since he was playing up the Stripperiffic costumes. Also inverted with the only real girl among them playing Daredevil.
- In the film Closer, Dan tricks Larry into thinking he's a girl, and they have cybersex.

- In Surrogates, Among the first victims of the OD, the operator of the seductive, female model surrogate at the nightclub that got fried, turns out to be an old, fat man. The characters don't treat this "revelation" as unusual or noteworthy in any way, implying this happens a lot.
- In Gamer, Kable's wife, a character in Society, is being controlled by Gorge, a topless and terribly obese home dweller.
- In the "People Can Lick Too" segment from Campfire Tales (1997), Amanda's chatroom pal Jessica is actually a guy who has been stalking her for the last few days. And now he knows that she'll be alone tonight.
- Discussed in Vlog. Brooke says that anytime you see a hot image of a girl claiming to be a lesbian, it is really a guy.

- Trilby and the Ghost, a short story by Yahtzee taking place in the Chzo Mythos 'verse, involves Trilby discovering a ghost who can't pass on to other realms because he's never met his japanese girlfriend Nariko face-to-face.

- These days this has been somewhat muddled, as close to 50% of the MMORPG players in recent times are women (apparently they are among the most popular "real" video games among the female populace), but often play as men due to either sexist character designs or horny teenagers hitting on them. There is a portion that plays male just to be in a hot guy's body, but we don't talk about those.
- 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.

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.

- in Goblins, Drowbabe is one according to Minmax.
