Ngakak is a widely used Indonesian slang word for loud, uncontrollable laughter, and clips labelled with it circulate on Indonesian meme pages, short video apps and soundboards as a shorthand for finding something hilarious. Because the laugh needs no translation, it travels easily beyond Indonesian audiences, working as a universal reaction to fails, pranks and awkward moments. Its short length and raw, human energy keep it useful for quick edits where a longer laugh would slow the joke down.
