The phrase comes from the Cobra Kai dojo in The Karate Kid franchise and is tied to The Karate Kid Part III from 1989, where Cobra Kai represents a ruthless, never-quit fighting philosophy. It later gained a second life when the Cobra Kai series brought the dojo back into popular culture, turning its old motto into a recognisable rallying cry online. Fans now reuse the chant in edits and memes because it instantly signals loyalty, toughness and refusing to stay down.
