Unlike clips taken from a famous show or film, this sound circulates mainly as a short user-shared laugh, with no widely documented original video or character behind the name Santiago. Its appeal online comes from its simplicity: a recognisable human laugh is easy to drop into memes, reaction videos and short-form edits without needing context or subtitles. Because laughter translates across languages and platforms, creators keep reusing it as a quick, relatable reaction whenever a joke, fail or unexpected moment needs an instant human response.
