Gul Khuiul circulates online as a short soundboard clip with a transliterated Russian title, and its original recording source is not clearly documented. That mystery has not stopped editors from reusing the steady hum as a ready made reaction sound. It is shared mainly as a downloadable MP3 for memes, edits and streams, where the flat drone works as shorthand for emptiness, malfunction or a thought process shutting down. Because the clip is short and has no words, it fits almost any language and any platform without needing context or explanation.
