The idea comes from Spider-Man: Across the Spider-Verse (2023), where Miguel O'Hara and the Spider-Society explain that every Spider-Person has canon events, fixed tragedies and milestones that must happen or their universe unravels. The concept spread on TikTok in 2023, where creators filmed themselves watching a friend make a doomed choice and refusing to intervene because it was a canon event. The sound became shorthand for that joke, and it is still used whenever a moment feels inevitable, fated or too familiar to stop.
