The phrase draws on the long-running conflict between DC Comics hero Barry Allen, the Flash, and his enemy Eobard Thawne, better known as Reverse-Flash. Online creators expanded that rivalry into a meme format where Thawne claims responsibility for increasingly petty, impossible, or embarrassing moments in Barry’s life. Many examples are parody dialogue rather than quotations from one canonical scene. The format spread through image captions, copypasta posts, voice edits, and short videos because the dramatic confession can turn almost any minor setback into elaborate supervillain sabotage.
