The clip comes from Killer Instinct, the fighting game first released in arcades in 1994 by Rare and Nintendo. In the game the announcer calls out combo ranks, with Ultra Combo reserved for a long finishing sequence that ends a match. Players recorded and shared the longest Ultra shout online, where fighting game fans turned it into a reaction sound for dominant wins. It remains popular because the callout is instantly recognisable to retro gamers while still reading as pure hype to everyone else.
