The 'There Is 1 Impostor Among Us' meme originates from the 2018 social deduction game Among Us, which exploded in popularity during the 2020 lockdowns. The template captures the dramatic moment at the start of a match when players are warned that a saboteur is in their midst. It quickly evolved beyond gaming, becoming a universal shorthand for identifying something that doesn't belong or someone acting 'sus.' Whether used for group photos, product comparisons, or social commentary, the meme relies on the humor of spotting a subtle deception within an otherwise uniform group.
