Siririca circulates online as a user-shared meme audio, with its name and Portuguese-language tag suggesting it comes from Brazilian meme culture rather than a film, game, or television show. It has spread mainly through soundboards and short-form meme sharing, where listeners save and replay clips they find funny rather than following a single original video. That low-key, community-driven spread is also why it endures: it is easy to drop into a joke, recognisable to people who know the reference, and flexible enough to fit reaction edits, pranks, and chat humour.
