Risadinha da maconha is Portuguese for little marijuana laugh, and risada da maconha is the fuller form shared in file titles. The clip spread as a short Brazilian meme audio through soundboards, group chats and video edits, where kkkk is the usual written form of laughter. Its appeal is its brevity and its very recognisable spaced-out giggle, which needs no setup or context to read as stoned amusement. It remains a staple reaction sound for jokes about getting the giggles, zoning out or laughing at nothing.
Sobre este sonido
Short Brazilian stoner giggle known as risadinha da maconha, a high, goofy laugh used in memes, chats and videos for someone laughing uncontrollably.
This is a short, infectious burst of giggling, just over two seconds long, with the loose, high-pitched sound of someone who cannot stop laughing. The laugh comes in quick, snorting little waves rather than one clean chuckle, which makes it feel silly, spaced-out and a bit contagious. It is the classic stoner laugh in Brazilian internet slang, the sound of finding something far funnier than it really is. Played on its own it instantly signals amusement, and dropped after a joke it makes even a flat line feel like the funniest thing in the room.
