This clip is shared as a user-uploaded gaming sound, named for Omar and a PUBG session rather than for a film, show or commercial release. That informal, player-made character is part of its appeal: it sounds like something caught on a microphone during casual play, not a polished studio effect. Short burp reactions like this are easy to reuse in stream highlights, fail videos and group-chat jokes, because the humour is immediate and needs no setup. Its brevity also makes it useful as a quick sting between longer clips.
