This clip circulates as a generic caveman sound effect rather than a line from a specific film, show or viral video, and its second version label suggests it was edited from a longer vocal performance for soundboard use. Online creators have adopted it as shorthand for prehistoric behaviour, using the grunts to sell caveman characters, Stone Age parodies and primitive reactions without needing any dialogue. Its staying power comes from that instant recognition, as a few seconds of guttural noise can set a whole scene in a comedy edit.
