The clip comes from Totally Accurate Battle Simulator, the physics-based battle game where wobbly units from different factions fight in chaotic simulated battles. The clubber is a tribal unit armed with a simple club, and its attack vocal is one of the short grunts players hear during melee combat. Short game sounds like this have spread through soundboards and gameplay edits, where creators reuse them outside the game itself. It remains useful because it is instantly recognisable as a primitive battle shout, even to viewers who have never played TABS.
