Watafok is a phonetic, text-style spelling of the English phrase what the fuck as it is written and joked about in French online slang, which explains the France and français tags attached to the upload. The clip has no confirmed film, show or creator source, so it circulates purely as a standalone reaction sound on soundboards and in short edits. Its appeal sits alongside a bruh reaction, short, instantly readable and easy to reuse whenever a post, fail or message makes no sense.
