This sound comes from Smiling Friends, the adult animated television series created by Zach Hadel and Michael Cusack. Charlie is one of the show's main characters, and short vocal moments like this spread online because they fit quick reaction edits so well. Fans clip screams, yells and awkward line deliveries from the show for memes, gaming videos and reposted reaction content. Its appeal comes from how instantly recognizable the voice is and how neatly the scream fits a one-second comedic cut.
