The line comes from the 2004 comedy film Napoleon Dynamite, in which Napoleon Dynamite shouts at Tina, the llama kept at his family's home, to come and get some dinner. The scene's deadpan delivery and odd insult made it an easy line for fans to quote, and it later circulated widely as a short meme sound on social media and soundboards. It remains popular because it is short, instantly recognizable to fans of the film, and fits almost any moment when an animal or person is eagerly heading for food.
