The 'Day 'n' Nite' meme is inspired by Kid Cudi's 2008 breakout hit, specifically the lyrics 'The lonely stoner seems to free his mind at night.' In internet culture, especially on platforms like TikTok and YouTube, the trend evolved into short animations or video clips depicting a drastic shift in personality or behavior between day and night. Users often use the template to show a professional or mundane daytime persona contrasting with a chaotic, creative, or gaming-focused nighttime life. It resonates deeply with audiences who relate to the 'double life' aspect of modern social habits and the introspective, late-night atmosphere of the song's iconic beat.
