The Evil Duolingo Owl meme, often associated with the phrase 'Spanish or Vanish,' centers on the persistent and increasingly assertive nature of the Duolingo app’s push notifications. What began as a harmless mascot named Duo quickly evolved into a sinister internet figure after users joked about the 'threats' they felt when breaking their daily learning streaks. The meme gained massive traction on Twitter and Tumblr around 2017, depicting the owl stalking users, breaking into homes, or holding weapons to enforce language practice. It highlights the collective anxiety of maintaining digital streaks and has since been embraced by Duolingo’s official marketing team, solidifying the owl’s reputation as a lovable yet low-key terrifying language enforcer.
