Risada is the Portuguese word for laughter, and short clips labelled Risada EVx circulate online as compact reaction sounds for memes, chats and short-form videos. The name appears to come from a user-uploaded soundboard clip rather than a film, television show or widely known character, so its appeal rests on the sound itself rather than a recognisable source. Its length of just over a second suits fast edits, where a brief human laugh can punctuate a joke without slowing the pace. That simplicity has kept it useful as a reusable reaction for creators sharing funny moments across social platforms.
