The mor mor moooor sound circulates online as a short user uploaded soundboard clip with no clear credited source, artist or original work attached to it. Its Russian language title is simply a written out version of the noise itself, which is how it has spread through shares and reposts. Clips built on stretched nonsense vocals became a staple of meme editing because they need no context to understand, and this one is now used mainly as a reaction sound, a filler gag and an intentionally annoying punchline in short videos.
