Combo Breaker comes from Killer Instinct, the fighting game first released in arcades in 1994, where the announcer calls out the move that interrupts an opponent's combo. As players shared matches and highlight reels online, the shout became shorthand for stopping someone who was on a roll. It later spread through gaming streams, reaction videos and memes, where it is often used far from its original fighting game context. Its staying power comes from that instant clarity: everyone understands that the run is over.
