The phrase itself is everyday internet shorthand, with tf standing in for a stronger expression of disbelief, and the clip spread as a reusable reaction rather than a quote tied to a named source. It circulates on soundboards and in short form edits where creators need a fast, recognisable way to mark something as bizarre. Its appeal is its brevity and tone, which fit Discord calls, comment threads and meme compilations, and it remains popular because almost any odd moment can be framed with the same baffled response.
