The line comes from Forrest Gump, released in 1994, where Forrest narrates his friendship with Benjamin Buford Blue, nicknamed Bubba, his army friend obsessed with shrimp. Online, the short narration became a reusable setup for any memory that is about to be quoted, much like it was at this moment he knew clips frame a sudden realization. Editors keep using it because Forrest's sincere delivery promises deep wisdom, so whatever ordinary, funny, or absurd line follows feels bigger, more memorable, and instantly recognizable to movie fans.
