Ngakak is Indonesian and Malay slang for laughing uncontrollably, similar to saying cracking up in English, and it became a common label for short laugh clips shared across social media and messaging apps. Sounds filed under this name are usually brief, exaggerated reactions rather than clips from a film or show, passed around as soundboard buttons and chat stickers in audio form. Its popularity comes from how instantly readable it is in fast meme edits, where a three second laugh can replace any written reaction.
