The clip comes from Hellsing Ultimate Abridged Episode 2 by Team Four Star, the YouTube parody series that re-dubs the Hellsing Ultimate anime with a comedic rewrite and new voice performances. TFS built a large following through abridged anime parodies, and short, quotable lines from the episodes were widely clipped and reused as reaction audio. This waiting line survived outside the full episode because it needs no plot context to understand, so creators can drop it into gaming, streaming and everyday delay jokes and viewers get the gag instantly.
