Avengers: Endgame opened in the United States on April 22nd, 20191. During the Battle of New York time-travel sequence, Tony Stark catches a glimpse of 2012 Steve Rogers and cracks that the old Avengers suit design "did nothing for your ass," which prompts Scott Lang to reply, "You look great, Cap. As far as I'm concerned, that's America's ass"2. Later in the same 2012 trip, 2023 Steve knocks out his younger self, stands over the unconscious body, and remarks, "That is America's ass"1.

How It Spread

On April 28th, 2019, Twitter user @evanswrth kicked off the fan reaction with a mock tribute ending "by the way we love your ass," which pulled over 18,000 retweets and 78,000 likes in four days3. The next day, @goodbeanalt posted a DNA double helix built from American flag and peach emojis, an image that passed 167,000 retweets and 666,000 likes in three days3. On April 30th, @STEVEROGERSBUTT arranged flag emojis into a buttocks shape and cleared over 63,000 retweets in two days3.

Outlets including BuzzFeed, ComicBook.com and PopBuzz wrote up the meme's rise as it moved out of Marvel fan spaces into wider Twitter, with ComicBook.com noting that MCU fans' talk of Steve's backside had reached "a new fever pitch" after the film2.

How to Use This Meme

The format typically pairs a screenshot or reference to Chris Evans as Steve Rogers with patriotic imagery, most often American flag emojis stacked into a butt shape or peach emojis subbed in for the punchline3. Quote tweets and captions frequently echo Scott Lang's line or the "That is America's ass" delivery, and reaction videos riff on someone showing off their rear as a stand-in for Cap1.
