This kind of goofy rawr sound is mainly used as a reaction-style meme clip rather than a widely documented quote from one specific source. It spread through short-form edits where creators add a fake feral or monster noise to awkward poses, pet clips, and intentionally cringey reveals. Its appeal is simple: the rawr sounds harmless and overacted, so it turns supposed aggression into comedy. It is often grouped with other goofy ahh sounds and similar meme audio used to sabotage dramatic timing on purpose.
