The line comes from The Mask, the 1994 comedy starring Jim Carrey as Stanley Ipkiss, a mild bank clerk transformed by a magical mask into a wild, cartoonlike alter ego. In the film the phrase captures the character's gleeful loss of restraint during his nightclub and city rampages. Clips of Carrey's performance circulated for years in compilations and reaction edits, and the short shout became a standalone somebody stop me meme. Its clear delivery and recognisable voice keep it useful when creators need instant, exaggerated confidence.
