Oink oink is the standard written and spoken imitation of a pig sound in English, and short clips of it have circulated online as a reusable meme noise for years. The version here is also shared with the Spanish words puerquitos, meaning little pigs, which hints at how widely the joke travels across languages. It stays popular because it needs no setup, works for farm animals, food jokes and teasing friends, and can be dropped into almost any short video without explaining the reference to viewers at all.
