The K.O. call comes from Street Fighter IV, Capcom's fighting game released in arcades in 2008 and on consoles in 2009. The knockout announcement has been part of the Street Fighter series since its early arcade days, marking the exact moment a health bar empties. In the fourth entry the voice was made deeper and more reverberant to match its bold ink-brushed art style. Clips of the call later spread through gaming videos and meme edits, where it is now used far beyond actual matches to signal a decisive defeat.

The Street Fighter IV K.O. sound effect is the announcer's dramatic knockout call from the fighting game, used for fight endings and gaming edits.
This is the iconic K.O. announcement from Street Fighter IV, delivered by the game's announcer in a deep, echoing shout as a fighter is defeated. The call stretches out with reverb and force, landing right as the loser hits the ground and the screen freezes for the knockout moment. It feels huge and final, instantly ending any argument inside the match. The clipped, powerful delivery gives even a short clip the weight of a real arcade finish, which is why it reads clearly as a victory moment.
