Ketawa bengek comes from Indonesian internet slang, where ketawa means laugh and bengek describes wheezing or being out of breath from laughing too hard. The clip spread through Indonesian meme pages, WhatsApp groups and short video edits as a ready made laugh track for jokes, fails and prank reactions. Because the wheeze is recognisable even without any words, creators outside Indonesia also use it as a universal sign of helpless laughter. Its short length and clear start and end have kept it popular for quick reaction edits.
