The clip is tied to Pop Smoke, the Brooklyn rapper whose "Woo" ad-lib became closely associated with his image and drill-era sound in the late 2010s. After his rise, the vocal tag spread beyond music clips into short-form edits, meme compilations and reaction posts. People kept using it because the delivery is instantly recognizable and communicates energy, confidence and pressure in just one word, which makes it easy to drop into fast-paced internet videos.
