James Robinson's Justice League: Cry for Justice miniseries quickly developed a meme of fans derisively posting "JUSTICE!" in relation to it, after several characters in the first issue all ended extended monologues by yelling "I want JUSTICE!"
Also, due to an unfortunate choice of font, it's also been referred to as "Gay for Justice◊".
The "Gay for Justice" meme also got appropriated by Alan Scott as of the New 52, where his character was rebooted as homosexual in the series Earth 2. (Coincidentally, both series are written by James Robinson.)
ALL HAIL DARKSEID! Explanation As of Nu52, this appears to be the badass creed of Darkseid's forces when they enter battle. First used by Bruutal aka brainwashed Omega Force enhanced Earth 2 Superman. .]]
Marvel'sCivil War miniseries's catch phrase was "Whose side are you on?", referring to the conflict between Captain America and Iron Man. This spawned a lot of messageboard signatures proclaiming "I'm with Cap", "I'm with Tony", and other, more absurd, choices, such as "I'm with Stupid" and "We don't care".
For Americans who took it a little too literally, "I'm with Lincoln," or "I'm with Davis."
Taking it one step further, with "I'm with Oliver" and "I'm with Charles" version or "I'm with Durruti" and "I'm with Francisco".
The Appendix to the Official Handbook of the Marvel Universe website had "I'm down with Howard", a Call Back to an earlier "Howard for President" meme.
HE/SHE/IT IS A SKRULL! (lesser-used DC variation: It's a White Martian! or It's Clayface! or It's a Skrull! regardless) Explanation From Secret Invasion, where a number of characters were revealed to be... well, Skrulls.
Even better: ANAL SKRULLS! (What separates them from regular Skrulls is known only to Warren Ellis.)
Don't forget Colossus. He isn't made of steel. HE IS MADE OF RAGE!
"Whoof. Just a moment, not done with 'whoof'."
And Kitty Pryde would like to remind you that PROFESSOR XAVIER IS A JERK!
"Welcome to the X-Men, [[X]]—Hope You Survive the Experience!" First used with Kitty Pryde's debut with the team, it was later used for Havok on the cover of Uncanny X-Men #219 and the Classic X-Men reprint of issue 171, amongst other places.
"To me, my X-Men!" It began as Professor X's Catch Phrase and later was picked up by both people mocking the team and by actual leaders like Cyclops.
With the success of the New 52 at DC and Avengers vs. X-Men promising big changes, it became popular for a while to claim, whenever Marvel was about to make an announcement, that a Continuity Reboot was just around the corner. Marvel employees actually had to shoot this rumor down several times.
Cyclops Was Right Explanation Many fans think that Cyclops' thoughts about what the Phoenix Force would do in Avengers vs. X-Men was right and he was right all along — that mutantkind was to be restored by the Phoenix and that the Avengers' actions were indeed in the wrong. This also paints him as a more martyr-like figure à la the "Magneto Was Right" slogan of long ago.
Lots of people on the Internet consider the last few years of Garfield to be the blandest, most mediocre comic strip in the newspapers today. Then in January 2006, someone created The Garfield Randomizer, which automatically selected three random panels from the entire Garfield online archive and mashed them together as a strip, turning it into Dadaist nonsense. It was praised as the funniest thing to happen to ''Garfield'' in years. Then Paws, Inc., told the creator to cease-and-desist. In a small measure of revenge, however, the creator made the code publicly available, and a few Garfield randomizers persist to this day (like this one).
Yet another variation is Tailsteak'sArbuckle, in which anyone is invited to redraw a Garfield comic in a different or more realistic art style, again with the thought bubbles removed.
"Lasagna Cat" takes the deconstruction even further. Real life strips are acted out in live action. The strip and the its date of publication are shown. The skit is accompanied by a brief music video. (Its the highlight, Post-modernism at its best)
Go back to bed, Garfield. o_O
Garfield is so malleable that they did one...just on Garfield barfing (then fart jokes, then crude sexual humor... sadly, it works) (warning, gross)
Jon's ferns (or any other plants for that matter...)
Garfield kicking Odie off the table
There was a strip a few years ago with Garfield eating a banana, then dropping the peel on the floor so that Jon would slip on it. Garfield uttered the line "a banana has two uses" and internet message boards have had a field day with it ever since.
WHO'S A MAN AND A HALF? I'M A MAN AND A HALF! A BERSERKER-PACKING MAN AND A HALF!
CHAINSAW! THE GREAT COMMUNICATOR!
STUPID STUPID STUPID IMP! YOU'RE STUPID AND YOU'RE GONNA BE STUPID AND DEAD!
Thanks to the dubious quality of his artwork, any picture posted that was drawn by Rob Liefeld is invariably met with the scream of "LIIIIEEEEEFFFFFFIIIIIEEEEELLLLLDDD!" The same is also done for Greg Land LAAAAAAAAAAAAAAAND!!!! This may or may not have been started by the user "foxhack" at scans_daily, but he sure helped popularize it.
While we're on the subject of Greg Land: Pornface!
Similar screams have been made as Take Thats against Joe Quesada (one of the minds behind the much-hated One More Day storyline in Spider-Man), DC's Dan Didio, and 4Kids Entertainment executive Al Khan.
Certain comic book covers become so often homaged and parodied by later cover artists, that showing someone the original cover elicits the response "So that's how (such-and-such an artist) came up with the cover of (some other comic)!"
Similar to the aforementioned Marvel Civil War messageboard banners, the recent "I Am An Avenger" posters depicting new teammembers have spawned numerous joke versions, such as this one.
Image Comics took this to a ridiculous extreme, using their parody posters to promote a fake "Guardians of the Globe" cast including a very thinly disguised Harry Potter ("Gary Popper"), Rick Grimes and Barack Obama as new members. The campaign was popular enough to get a back-up strip in the actual team's comic.
Suicide Squid Explanation A poster in the rec.arts.comics newsgroup made a typo when asking about recent developments in Suicide Squad. Group members made up an entire storyline for the nonexistent character. The newsgroup's annual awards were even named "The Squiddies".
"Well, back to the old drawing board!" Explanation originates from a 1941New Yorker cartoon by Peter Arno.
"Just give me FIVE MINUTES with the genius who decided _____!"Explanation The first panel of Fish Police Issue 1 has Inspector Gill looking up a staircase and yelling, "Just give me FIVE MINUTES with the genius who decided fish should use stairs!''
