Que cheiro de maconha is a Portuguese-language phrase that translates roughly as 'what a smell of weed,' and it circulates online as a short spoken meme clip. Its humour comes from the blunt, everyday way the speaker calls out an unmistakable smell, a moment many Brazilian viewers recognise from parties, streets, and apartment buildings. Shared in chats, reaction videos, and short-form edits, it survives because it is instantly recognisable, easy to drop over a visual gag, and broad enough to fit any scene where someone notices something suspicious in the air.
