The phrase is Chilean style Spanish, using the informal chupai form, and the final word is shortened to pi, softening a very crude expression just enough for sharing. Short voice notes like this circulate on soundboards and in chats because they can be dropped into almost any annoying exchange without explanation. Its popularity comes from the contrast between the tiny runtime and the aggressive attitude packed into it. It remains a niche Spanish language meme reply rather than a sound tied to a confirmed film, series or celebrity recording.
