The clip circulates online as a short name-call sound, shared on soundboards under spellings like Hassan Kanuuu and Hassankanuuu. Its humor comes from the stretched final syllable, which turns a simple shout into something instantly recognizable even without any visual context. Creators reuse it as a reusable reaction insert rather than as part of a longer scene, dropping it into memes, gaming edits, and chat videos whenever a dramatic introduction is needed. The lack of a widely known source has helped it spread as a standalone audio joke.
