The clip comes from Piccolo, the Namekian warrior from Dragon Ball Z, in the Japanese dub of the Broly movie, where his short kiai is used as a battle cry during a fight. Short anime vocal bursts like this travelled through soundboards and editing communities because they are easy to recognise and drop into a scene without dialogue. Fans still reuse Piccolo's shout for Dragon Ball edits, reaction videos and meme cuts, where a familiar voice instantly signals effort, power and a sudden attack.
