Little verified information is available about the origin of Ertha, and its published listing gives no clear source work, character or release year, so it is best understood as a community shared game clip rather than a widely documented meme. It appears in a games collection on soundboards, where short audio moments are saved, replayed and passed between players and editors. Its small but steady audience suggests it survives through niche recognition and repeat use in gameplay edits, rather than through a viral breakout or a famous scene.
