What does Canon Event mean?

A canon event is a painful but formative experience you must go through because it shapes who you become — and others should not intervene. Borrowed from Spider-Man: Across the Spider-Verse (2023), it is used jokingly about bad haircuts, doomed relationships, and first-job mistakes: "I can't interfere, it's a canon event."

In the film, canon events are fixed points in every Spider-person's story that cannot be changed without destroying their universe. TikTok adopted the term within days of release: watching a friend text their ex, dye their own hair, or move for a partner became "a canon event" you must let happen.

The phrase endures because it wraps empathy in comedy — it acknowledges the mistake is inevitable and character-building. It appears in storytimes ("my villain origin canon event"), parenting humor, and advice content. It pairs naturally with "character development" and "lore" as narrative-framing slang.

Era

An era is a self-declared life phase framed like a pop star's album cycle: "in my villain era," "in my soft girl era," "in my gym era." Popularized by stan culture (and supercharged by Taylor Swift's Eras Tour), it turns any habit or mood into an identity with a name.

Main Character Energy

Main character energy means living like the protagonist of your own story — confident, intentional, romanticizing everyday life. Born from TikTok's 2020 "romanticize your life" trend, it is mostly aspirational, though calling someone "the main character" can also mock self-centered behavior.

Roman Empire

Your "Roman Empire" is a topic you think about constantly for no practical reason. It comes from a viral 2023 trend where women asked men how often they think about the actual Roman Empire — and the answers ("weekly, at least") shocked everyone. Now any recurring obsession qualifies.
