The name is Portuguese for a little laugh, and the clip circulates online as a compact reaction sound rather than as part of a widely documented film, song or television scene. Its appeal is its brevity: at under a second, it can be dropped into memes, edits and chat reactions without interrupting the action around it. Because the laugh sounds informal and human, creators keep returning to it for light teasing and playful responses, especially in short-form video where a single audible cue has to do the work of a caption.
