The exact source of this clip is unclear from the available information, but online it is used as a compact reaction sound centered on the phrase “I hate Peter.” Its popularity comes from how fast it delivers a recognizable feeling: annoyance, dismissal, or exaggerated personal hatred for comedic effect. Very short voice clips like this spread easily through meme edits, reposted reaction videos, and soundboards because they can be dropped into almost any format without setup. That flexibility is why it keeps showing up in joke content.
