The precise origin of this clip is unverified: its embedded file tags credit voice actor Matthew Mercer and title it 'The White Worm', but that metadata comes from a user upload and may simply reflect where the uploader sourced it. Short monster vocalizations like this circulate widely among editors because a sub-two-second snarl is endlessly reusable — it slots into gaming montages, tabletop RPG actual-play clips and horror edits wherever something vile needs to announce itself. Its staying power comes from utility rather than fame: it is a tool sound, not a catchphrase.
