Karate Chop is a Fighting type move in the Pokemon series, and Pokemon Stadium brought those battles into 3D on the Nintendo 64, first released in Japan in 1999. In the game the move is paired with a short striking sound that signals a direct hit. Clips of that hit later circulated on soundboards detached from gameplay. Like Doge bonk, it is now borrowed for unrelated videos where a single comedic impact needs to land instantly, keeping a brief Nintendo era battle effect in use long after the original match ends.
