This meme sound is based on Renato Cariani's laugh, a voice clip that spread across Brazilian social media and short-form edits. Rather than functioning as a full quote, it is usually used as a fast reaction insert, similar to a bruh moment, to mark irony or secondhand embarrassment. The clip stayed popular because it is short, instantly recognizable to many Portuguese-speaking viewers, and easy to drop into montage humor, gym content and group chat videos.
