The exact source of this yeah and laugh clip is not documented, which is common for short vocal sounds that circulate through meme pages, edits and soundboards. Its appeal is purely functional: two seconds of unmistakable celebration that needs no context to land. Editors favour it because the laugh reads as playful rather than mean, so it works for friendly roasts, sports highlights and reaction compilations alike. Like many bite-size reaction sounds, it survives on reuse, staying popular as long as creators need a fast, upbeat button for a funny moment.
