Dwayne Johnson built The Rock persona in WWE in the late 1990s, where exaggerated promo threats and catchphrases like whooping ass became part of his character. Clips of those promos have circulated for years on wrestling pages and meme soundboards, shortened into standalone reactions. This version trims the line to a few seconds, which makes it easy to reuse outside wrestling context. It stays popular because the delivery is instantly recognisable, even for viewers who never watched his matches, and it works as both a joke threat and a hype moment.
