Meirzhan circulates online as a short personal name sound rather than a clip from a widely known film, song or television show, and its exact original recording is not widely documented. That kind of brief name callout is easy to reuse: it can be dropped into a video, message or stream whenever the name itself is the joke, the introduction or the reaction. Because it is so short and instantly recognisable to anyone who knows a Meirzhan, it works as an inside joke that needs no explanation, which helps small personal sounds keep spreading between friends and creators.
