The sound is tied to Yoshi, Nintendo’s dinosaur character from the Mario series, whose long tongue is a signature gameplay move across many games. Online, people usually search for it as a Yoshi eating sound or Yoshi tongue sound when editing short memes, gameplay highlights and reaction clips. It stays popular because the effect is instantly readable even in a fraction of a second: you hear it and immediately understand that something was snatched, swallowed or picked up in a playful way.
