This sound is associated with DragonBall Z Abridged, the fan parody series by TeamFourStar that became widely quoted online in the 2010s. Piccolo's yelled warning turned into a standalone reaction clip because the line is brief, clear and easy to drop into edits. It spread through anime meme pages, YouTube compilations and short-form reaction videos, where creators use it to highlight moments when a person ignores an obvious threat. Its staying power comes from being instantly understandable even outside the original scene.
