Risada Cazalbé is a long-running Brazilian reaction sound that became popular online as a quick audio cue for irony and embarrassment. It is commonly shared in meme edits, short videos and chat reposts, especially when someone says something unintentionally funny or visibly fails. Its staying power comes from how instantly the laugh changes the mood of a clip, much like a bruh reaction or other short meme stingers used to underline a punchline.
