The line comes from Pig in Back at the Barnyard, the Nickelodeon animated series about farm animals living like people, and is taken from the episode 'Home Sweet Hole'. Pig is known for his good nature and sudden bursts of panic, which made the shout easy to lift out of context. Online, it spread as a reaction sound for moments when the same annoyance keeps happening, especially in short videos, edits and soundboards. Its simple wording and instantly recognisable frustration keep it useful long after the show ended.
