The story arc of a player — or occasionally a streamer or pro — during which their gameplay deteriorates so badly, so publicly, and so consistently that observers begin narrating it as a character development.

The arc framing implies it has a beginning, a chaotic middle, and an eventual resolution — usually either a ban, a public breakdown, or an unexpected comeback that redeems the whole thing cinematically.
A trust arc is the full narrative journey of trust in a relationship — from the cautious early days, through the tests and betrayals, up to whatever level of confidence you eventually land at. Borrowed from storytelling vocabulary, it acknowledges that trust isn't a static fact but a plot that develops over time. People online use it when reflecting on how their feelings about someone evolved, especially after situations that forced a reckoning. Having a trust arc means the relationship was real enough to have chapters.
The narrative trajectory of someone who transitions from trustworthy to completely fake — the visible story of a person's descent into snake behavior that, looking back, always had the signs. A snake arc is most often spotted in retrospect: the small betrayals you dismissed, the loyalty that started slipping, the gradual shift in energy right before the knife went in. It's become a staple of social postmortems and group chat autopsy sessions where everyone traces exactly when things went wrong.
A sus arc is the narrative stretch in someone's life or a group dynamic where one person goes from normal to deeply suspicious in everyone's eyes.

Sus arc treats interpersonal drama with the same analytical seriousness fans apply to fictional character development, which is peak chronically online behavior.
