Dwayne Johnson built The Rock persona in WWE in the late 1990s, where loud, insult driven promos and catchphrases made his voice instantly recognisable even without video. Clips of his confrontations later spread online as standalone reaction audio on soundboards, in memes and in short form edits. This shut up version follows the same use as other shutdown sounds like shut up mom, kept popular because a single recognisable celebrity shout can end a joke, argument or rant without any context.
