The sound comes from The Elder Scrolls IV: Oblivion, Bethesda's 2006 role playing game known for its stiff NPC conversations and expressive character faces. Players began isolating short NPC grunts and eating noises, spelling the guttural loop as HRGRGRGHRGR in titles and comments. The clip spread through gaming forums, YouTube edits and soundboards because it summed up Oblivion's unintentionally funny dialogue energy in just over a second. It remains popular as a shorthand for mindless chewing, strain and mock anger in meme videos.
