The phrase 'combo breaker' comes from fighting games, where interrupting an opponent's combo is a match-turning moment, and it was cemented by the Killer Instinct series and its hype-man announcer in the 1990s. Clips of the call spread through gaming montages, streams and meme edits, where 'C-C-C-combo breaker' became shorthand for any stopped streak. Uploads spelled 'charlie' usually reflect how the rapid 'C-C-C' sounds to new listeners. It endures because three seconds of shouted interruption fits almost any fail.
