The 'Reverse Snap' meme refers to the pivotal moment in the Marvel Cinematic Universe where the devastating effects of Thanos's initial snap are finally undone. Whether it's the Hulk using the Nano Gauntlet in Avengers: Endgame or Tony Stark's final sacrifice, this template represents the restoration of order or the sudden return of something thought to be lost forever. In meme culture, it is frequently used to symbolize 'undo' moments in real life, fixing a massive error, or bringing back a dead trend. Its versatility allows creators to celebrate a triumphant return or mock the chaotic consequences of things suddenly reappearing after a long absence.
