it's canon
The shorter form, asserting something is now a fixed part of the story.
Declaring a mistake canon is a way of accepting it rather than fixing it.
slang term explained
A formative bad experience you are not supposed to prevent.
The short answer
A canon event is a difficult, embarrassing or painful experience treated as a necessary part of becoming who you are — a terrible first job, an obvious mistake, a relationship everyone could see failing. Interfering with someone’s canon event is framed as a mistake.
Background
The phrase comes from Spider-Man: Across the Spider-Verse (2023), in which certain events must happen in every Spider-Man’s story. Viewers immediately applied it to ordinary life, where it works as a way of declining to intervene.
In conversation
Use it about a mistake someone needs to make themselves, or about your own past with retrospective forgiveness.
