The sound circulates online as a Brazilian Portuguese meme known as Negão do escuro, a name that roughly means the man in the dark. It is shared as a short reaction audio in chats, edits and meme compilations, where the unseen laugh does the comic work without visual context. Its appeal comes from the contrast between a joyful, unrestrained laugh and total darkness, a combination that fits pranks, horror jokes and surprise reveals. Like other laughing clips such as the baby laughing meme and the cat laugh meme, it is reused because it is instantly recognisable as laughter.
