This sound is associated with DragonBall Z Abridged, the parody series by TeamFourStar that became hugely popular online through YouTube. Mr. Popo’s version of the character stood out for his eerie calm delivery and unsettling humor, which made his laugh especially memorable to fans. Over time, the clip spread through anime meme compilations, reaction edits and short-form videos as a quick way to signal creepy confidence or bizarre energy. It still gets used because the voice is instantly recognizable to DBZA viewers and funny even for people who only know it as a meme.
