A cap arc is when someone goes on an extended streak of lying, fabricating, and embellishing — a narrative phase where every interaction seems to add another layer of fiction on top of the last. Unlike a one-off cap, a cap arc has structure: it builds, escalates, and eventually collapses under its own weight when someone pulls the thread. The term borrows from storytelling vocabulary to describe the tragicomedy of watching someone spiral deeper into their own constructed reality, dragging their online reputation with them.
His whole cap arc finally ended when someone found the original video that proved none of it happened.
