The line comes from Forrest Gump, the 1994 film in which young Jenny shouts at Forrest to run as school bullies chase him, a moment that leads to his leg braces breaking apart and reveals his extraordinary speed. The phrase became one of the film's most quoted lines and later spread online as a short reaction clip for escapes, chases and last-minute dashes. It endures because the childhood urgency and the underdog triumph are instantly clear, even without seeing the film.
