Image Boards: the various banners at the top of the page often mocks the site itself. Users often use this as well:
They will generally poke fun at the stereotype that all of its members are socially inept, perma-virgin,shut-ins, and the humor may also vary depending on the particular board. For example, posters on /v/ will joke how having fun while playing a game is wrong since they all suck, new and old, and the main fitness guide on /fit/ assumes that its readers are most likely social failures and how obsessive /fit/ members are with the littlest of details in fitness and diet practices.
The pejorative term "fag", is used frequently as a suffix when referring to groups. When introducing themselves in a post, many users may point out that they are a Xfag, with X being an arbitrary group. While referring to another group as "Xfags" may be used as an insult, it is more frequently used as a non-hostile way to refer to oneself or another group.
"You're watching the Ebolaworld Channel. Why are you doing that?" "You're watching the Ebolaworld Channel. W..What?" "You're watching the Ebolaworld Channel... Weirdo!"
The Busy Street Mailbags, where hate mail sent by those aggravated by the site are picked apart, is usually accompanied by self-deprecating humor, with the commentators acknowledging the faults and weaknesses in their articles while mocking each other in good humor.
Cracked.com is fond of this, often saying how advice for living your life is coming from internet comedy writers, and then there are asides that raise questions as to the sanity of said internet comedy writers.
Many of Daniel O'Brien's articles are all about how much of an asshole he is. And Robert Brockway's tend to end with either him or the reader arrested for some outrageously drug-fueled mischief.
It's almost a Running Gag, at this point, for the writers to make fun of the site for making so many dick jokes.
The Dead Horse Interchange staff frequently make reference to their "internet has-been" status, their self-described perma-virginity, greed, lack of talent, and inability to maintain frequent updates. Ebeeto is an "understimulated hermit Swede", Monty is a "Charlie Brooker-lite alcoholic teenager", and Schlasser being a "ripoff of The Angry Video Game Nerd".
In Whateley Universe stories, most of the canon authors have an Author Avatar. All of them are members of the Whitman Literary Girls, all have annoying characteristics, and all of them wish they were the big heroes who get to save people and stuff. They're not.
Phase constantly puts himself down by comparing himself to his friends, other, more powerful students, and superheroes. Thing is, he's an incredibly powerful character, has a number of very versatile attacks, and is continually shown to be much better in nearly every aspect than he thinks he is. Poor bastard has no self-esteem.
Any reviewer on Channel Awesome will indulge in it every now and then. Todd in the Shadows even explained this behavior as "because otherwise, I would just be some bitter, pathetic jerk-off talking smack about people who have accomplished things a billion times better that I ever will, and that gets old real quick."
During his review of Jack Frost (1998), he mocks the article done about him on Entrepreneur magazine saying "They'll print anything these days".
Over the course of his reviews, he's been socially awkward, seriously obsessive about his childhood (which really seemed to suck for bigger reasons than just bad movies), goes on rants about "dreams not coming true" and sometimes not all that bright. Doug does love making his main character a mess.
In his tribute to Siskel & Ebert, he responded to Ebert's claim that Congo was intentionally So Bad, It's Good by sarcastically saying that Dominic from Video Game Confessions had a good Cockney accent
When Mara Wilson became peeved at Doug for mocking her acting, he wrote a list of insults that she could use on him if she wanted. She also had guest spots in later That Guy with the Glasses reviews of her movies where she wreaked horrible vengeance on them. (the first even brought the Critic's self deprecation further, as she replied to him criticizing her as a child actor by showing off his embarrassing teen videos - Doug deliberately picked the worst ones)
The Nostalgia Chick's "Thanks For The Feedback" videos paint her in a rather pathetic light, first with her best friend Nella saying that at least going on a date with the Critic will mean leaving the apartment for a few hours (her response is "We haven't watched the My Little Pony movie in three days!"), then answering the question of why Nella puts up with all her mistreatment by showing that the Chick pays Nella to be her friend and shore up her fragile self-esteem.
And of course, related to the above mention of Mara Wilson, she co-reviewed Matilda with the Chick.
Brows Held High is one of the highest in that regard. During his Naked Lunch review, Jyle "telepathically" confesses that he does this show to cover up his insecurities about his intelligence.
In their RP of Policenauts,Diabetus comments that the only thing sadder than reviewing the game would be hacking it. Slowbeef, who was working on a translation patch for the game at the time, commented: "I'll sa— Fuck you."
Many good Let's Players do this almost constantly. Common subjects include the infrequency of their updates/uploads, their voice/recording setup, and the vast amount of time they use to produce the videos instead of doing something productive.
A lot of Slashdotters crack jokes about living in their parent's basement, not having any love life, etc.
Similarly, Diggers make similar jokes, since one cannot have sex on the internet.
The Something Awful Forum Goons are pretty fond of this as well, but then again they don't take much seriously in the first place.
Most of the more self-aware Abridged Series do this, occasionally with the creators guest-starring on other people's Abridged Series in order to make fun of themselves.
LittleKuriboh of Yu-Gi-Oh! The Abridged Series does this pretty consistently. In one extreme case the characters wondered where he had gone for four months. Another time, he parodied his own proposal video and had his characters wonder what kind of "sick, lonely person" would do such a thing. In a later video, Yugi and Yami complain about LK's incredibly boring voice.
The creators of Ranma 1/2 Abridged are common employers of this trope. Sometimes it is a straight jab at themselves, and sometimes it is done ironically to take a subtle jab at some of the other Ranma 1/2 abridgedments, of which there are many.
Random Background Character: Yeah, that Sithis Bear guy sounds the same in every voice!
TeamFourStar's #TIBA abridging contest in 2016 had two of these: Firstly, the award given to the video that got the most audience votes but didn't make it into the judge's Top 30 was called the "F**k the Judges" Award. Secondly, before announcing the Top 30, the guys posted the absolute worst Abridged video they'd ever seen: the very first episode of DBZA itself, with the members of TFS doing commentary and ripping it apart for its poor quality.
In JourneyQuest, at the end of episode 7, Wren the bard is trying to figure out what to name her epic (which is about the series' events). She comes up with "Journey Quest", then discards the title.
Wren: I have to give it a name! Uh... well, it started out as a journey, and then it just kinda became this whole different quest... journey, quest... Journey Quest!... ugh, that's terrible.
While the persona Yahtzee of Zero Punctuation assumes in his videos, is that of a quite pompous, sarcastic, caustic critic, he often take pot-shots at himself, especially his awkward relationship withsexuality, and fully admits to often falling prey to some of the same shortcomings that he frequently criticizes developers for in his own games and writing.
Yahtzee: When you review games for a career—shut up, it's totally a career . . .
Key of Awesome's "Moves Like Jagger" parody illustrates the apparent difficulty of imitating Adam Levine by having Mark sing about being too fat to perform the parody, and Todd about being too weak. They end the song by calling themselves "attention whores" who will "do-o-o-o-o-o anything for laughter."
FIMFiction.net has had a lot of trouble with 502 errors. So much so that, for a time, they replaced their title banner with:
"502Fiction.net. We sometimes serve fanfiction."
TV Trash: In Rowdy's review of "Happy New Year Charlie Brown", he remarks that Charlie Brown was his dating guide. "I'm going to die alone!"
In Ultra Fast Pony, Wacarb frequently mocks his editing or lip-synching by slapping a "Quality editing!" subtitle (or some humorously misspelled variant) on scenes he considers sub-par, or by using a "This looks familiar..." subtitle to mock his overuse of certain clips. In "The Longest Episode", he takes a big swipe at the writers of the source material, then follows it up by implying that he's even worse.
Celestia: Whoever wrote this episode must have had brain damage. Twilight: Yeah, I think all the writers do. Subtitle: That's why I don't even have a brain!
In Google, you can start typing "why goo" and one of the term suggestions is "Why Google sucks". If you type "google is", two of the suggestions will be "Google is gay" and "Google is making us stupid". Typing "I hate g" will instantly show you "I hate Google". And so on.
The Honest Trailers for 300, the fiftieth episode, begins with, "Can you believe it? We made fifty of these dumb things."
Youtuber Yuriofwind often makes fun of his clinical depression, colorblindness, and stupid username. He'll also occasionally bring up an insulting comment from a previous video to verify that yes, it's true, but irrelevant.
SWAG.MOV has a Freeze-Frame Bonus appearing during a particularly ridiculous (even by the series' standards) scene, a giant bipedal Rainbow Dash summoning an enormous sword from the skies above with which to slay Discord.
THIS IS SO FUCKING RETARDED OH MY GOD I CAN'T BELIEVE I'M ANIMATING THIS.
SF Debris's Chuck Sonnenburg after spending the first eight minutes of his review of Transformers talking in deep detail about how the relationship of the summer blockbuster to science fiction is both blessing and curse. After the commercial break:
"Okay, I stand by everything I have said, and I do advocate rational discourse over a hurricane of trolls. But I'm also an Internet critic and part of the job is, well, this part of the show now, where I act like a guffawing dickhead."
Matthew Santoro often makes fun of himself for being bald, and being short.
GEOWeasel has its characters make fun of their own cartoon and its lack of viewers.
Weas: Nar, I think that comment may have cost us some of our viewers.
Buckley from A Dose of Buckley best summarizes this trope with "If you can't make fun of the things you love, you don't deserve to make fun of the things you hate".
CinemaSins reviews movies and assigns them a "sin count" based on how many plot holes, filmmaking errors, and things that the reviewer just thought was stupid they contained. What has the highest sin count? CinemaSins itself.note It was assigned an infinite number of sins. And that video plays automatically when one enters the CS channel!
In part one of "Bowser Junior's Summer School", Logan is one of the students in summer school, and Jackie Chu gives him a book called "YouTube for Dummies" and calls him dumb.
In the episode, "Bowser Junior's First Grade Part 4", a puppet version of Logan says that he wants to make Youtube videos when he grows up. Jackie Chu calls the idea dumb.
In "Bowser Junior's YouTube Channel!", after watching one of their fake pranks on YouTube, Junior and his friends notice a comment from SuperMarioLogan himself saying that it was "fake and gay", and Junior calls him "stupid".
The email "ladying" makes fun of the crude animation and weak characterization of the early cartoons on the site such as "Marshmallow's Last Stand".
In "Trogday '08", Strong Bad does a song about the "S is for Sucks" Dragon, complaining that "you Internet types ruined Trogdor, just like you did zombies, pirates, ninjas, and Strong Bad! Er, wait, no... yeah!"
Most of their videos in The New '10s mocks several outdated aspects of the website that haven't been updated since the early 2000s. (use of Flash, the website's layout, their incredibly infrequent update schedule).
