What is Reverse Snap?

Reverse Snap is the fan nickname for the Avengers: Endgame scene where Hulk undoes Thanos's Infinity War snap, and for the Reddit meme series imagining what happens when erased victims rematerialize at their exact prior coordinates.

Where did Reverse Snap come from?

Avengers: Endgame premiered on April 26, 2019. The earliest documented meme about reverse-snap physics was posted by Redditor thomasflow98 on r/dankmemes on May 6, 2019.

What does Reverse Snap mean?

In the film, it refers to Hulk reversing Thanos's genocide with the Infinity Gauntlet. Online, it refers to the fan theory that returning victims appear at their old spatial positions, with uncomfortable results.

How do you use Reverse Snap?

Most posts pair an Infinity War victim with the pose, activity, or location they were in during the first snap, then imagine the awkward rematerialization five years later. The Unsettled Tom template is a common choice.

Is Reverse Snap still popular?

The format spiked in May 2019 after Endgame's release and quieted once film discussion cooled off. It's remembered now as a classic Endgame-era Reddit joke rather than an active format.

Reverse Snap is the fan nickname for the Avengers: Endgame scene where Hulk uses the Infinity Gauntlet to bring back everyone Thanos erased in Avengers: Infinity War. Because the movie never explained whether returning victims kept their old spatial positions, Reddit spent May 2019 drafting meme scenarios imagining the awkward results. A single Unsettled Tom version in r/thanosdidnothingwrong hit 27,200 upvotes within 11 days.

Overview

The format plays with the physics loophole the movie left open: if victims return to the exact spot where they vanished, what happens when that spot is now underwater, airborne, or occupied by solid matter five years later? Typical setups show returning people reappearing in midair after Earth rotated away from their original coordinates, or stuck inside a wall, car, or another person standing there1.

Early examples leaned NSFW, with gags about pregnant women suddenly giving birth or couples caught during intimate acts2. Later jokes softened, imagining MCU side characters reappearing in whatever death scenario killed them the first time6.

Avengers: Endgame premiered in the United States on April 26, 20191. In its climactic sequence, Mark Ruffalo's Bruce Banner uses the Infinity Gauntlet to undo Thanos's snap from Avengers: Infinity War, restoring every victim. Fans quickly nicknamed the moment the 'reverse snap'4.

Because the film skipped over the mechanics of the return, viewers started asking pointed questions online about aging and spatial coordinates. On May 6, 2019, Redditor thomasflow98 posted an early example on r/dankmemes titled 'Oopsieee,' which played out one uncomfortable first-snap scenario and let commenters speculate on how the reverse would look2.

How It Spread

Four days later, on May 10, Redditor Punisher2003 followed up with a post about pregnant women during the original snap, with commenters again mapping out what the reverse would do5. On May 12, Redditor anshulans adapted the fan theory into an Unsettled Tom template on r/thanosdidnothingwrong, and that version hit 27,200 upvotes within 11 days3.

Through mid-May, more variations arrived in r/thanosdidnothingwrong and r/dankmemes, now naming specific characters. One post singled out Yondu, whose Guardians of the Galaxy Vol. 2 death left him in the vacuum of space6, and another ran the joke on anonymous MCU henchmen killed during the first snap7.

How to Use This Meme

Posts typically pair an Infinity War victim with the activity, position, or location they occupied at the exact second Thanos snapped. The five-year gap and unchanged coordinates make the sudden rematerialization absurd, lethal, or NSFW. Many versions use reaction templates such as Unsettled Tom3.
