The line comes from Shenmue, the story-driven adventure game developed by Sega for the Dreamcast. The game is famous for its detailed everyday life systems, including day-and-night cycles and NPC dialogue about daily routines, which is where a curfew-style line like this fits naturally. Clips of its earnest, slightly stiff voice acting have long circulated among retro gaming fans as in-jokes. This particular snippet endures because it works perfectly as a short, recognizable parental warning for memes about bedtimes, streams running late, and nights out.
