This clip comes from a user-generated soundboard rather than any film, show or game, and its original recording has no documented source, so it is best enjoyed as anonymous internet humor. The formula of a drawn-out vocal buildup crashing into an absurd animal impression is a classic meme structure, which is why the clip fits so naturally into reaction videos, fail compilations and shitpost edits. At about nine seconds it is short enough to drop into a single cut, and it keeps circulating because the contrast between the tense scream and the goofy pig grunts surprises people every time.
