The Bagel Effect is a concept originating from the Spider-Man: Into the Spider-Verse and Across the Spider-Verse films, highlighting the unintended consequences of Miles Morales' actions. In the first film, Miles jokingly throws a bagel at an Alchemax scientist, who later reveals himself as The Spot—a villain whose existence was triggered by that specific moment. This meme template is used to illustrate the butterfly effect, where a minor or silly decision leads to a massive, often disastrous, chain of events. Online, creators use it to mock how trivial mistakes can ruin everything or to joke about the convoluted nature of destiny in the multiverse.
