The internet is a great connector, a place where small communities can gather and flourish — and also where people who aren’t in those communities can stumble face first into a subcultural norm they were previously unaware of, leading to confusion, and, in the best case scenario, delight.

That is to say, this week, a lot of non-comics reading folks discovered that Dick Grayson, Nightwing, formerly Robin, has a lot of there in his derriére. A bit of a boost in his behind. A healthy chonk in his badonkadonk.

In fact, Nightwing trended on Twitter last night. All in thanks, it seems, to this viral Tweet:

Behold...the full set by @NicolaScottArt! pic.twitter.com/chFGtX3zDH — Comics Bookcase will be at NYCC (@ComicsBookcase) September 18, 2019

The tweet, from the blog Comics Bookcase, celebrates the completion of a set of four variant covers showcasing some of DC Comics’ oldest and biggest heroes: Superman, Batman, Wonder Woman, and Robin/Dick Grayson. They’re all drawn by veteran DC Comics artist Nicola Scott (Birds of Prey, Secret Six, Wonder Woman), showcasing seven to eight decades of artistic and costuming history in each image.

But one of these images is not like the other, and we’ve put them in a gallery below so you can get a full idea of it:

Like Batman and Superman before him, Dick Grayson, the first Robin, is approaching his 80th anniversary in 2020. In his final pose in his modern costume, it’s clear that he wants the viewer to know that he’s a versatile character with many facets, and also many assets.

This was both surprising and confusing for many folks, and the memes came on thicc — er, thick.

Batman, I'm trying to sneak around but I'm dummy thicc and the clap from my ass cheeks keeps alerting Joker https://t.co/fB5Jiyd0qo — Hewwo (@Shy_MeMer) September 19, 2019

Nightwing out here in full Thicc Grayson mode.

Ass so big you can bounce that huge coin in the bat cave off it.

Villains quit fearing the bat signal & just run when they hear those cheeks clapping in the distance.

At this point he doesn't need a utility belt, that is an arsenal. https://t.co/PkPmBZ4y0c — AlphaOmegaSin (@AlphaOmegaSin) September 19, 2019

But for every person surprised by Nightwing’s squat-heavy workout routine, there was a comics fan to appreciate the attention to detail.

Nightwing's ass is an important part of his character and I'm glad it's getting the respect it deserves https://t.co/x48OHoA0kK — 「AAAAAAAAAAAAAAA」 (@antahoney) September 19, 2019

Thank you for capturing Dick's butt.

Arguably the best butt in comics... — Dr. Dena. PhD (@IsItBrokenYet) September 18, 2019

The idea that Dick Grayson has a great butt is a long-running gag in the DC Universe. He’s a character with a long-standing appeal to readers who are attracted to men, and the fact that his Nightwing costume lacks a cape puts his tightly-clad butt on easy display whenever he’s facing away from the reader. (Not something Batman or Superman can claim.)

Nicola Scott, the aforementioned artist behind this series of covers, is one of the better known contributors to the legend of Dick Grayson’s butt. While it’s by no means the only example of her work in this area, a panel she drew for 2009’s Secret Six #9 is often used as a sort of ur-example of the trope.

In more recent Nightwing lore, it’s been established that even when his face is disguised by advanced brain-altering nanotechnology, multiple characters in the DC Universe can identify him by the shape of his butt alone.

So if you didn’t know that Nightwing has a great ass, now you do. Use this knowledge wisely.
