The exact origin of this version is unclear, but the honk shoo mimimi format became a widely shared online sleep meme through short-form videos, reposts, and captioned reaction edits. People spell it many ways, including snore mimimi, honk shoo mimi, and mimimimimi, which helped it spread as a text joke as well as an audio clip. It remains popular because the sound instantly signals fake, cartoon sleep in a way that feels both silly and oddly cute, making it easy to reuse across pet, gaming, and reaction content.
