The exact origin of the Eduardo Otario recording is not confirmed, but the clip circulates in Brazilian meme and soundboard collections as a short prank reaction. Pegadinha means prank in Portuguese, and the repeated hayeye delivery gives it the feel of an old WhatsApp forward that keeps getting reshared. It spread through short video edits, gaming clips and group chats where a quick teasing sound is needed, and it remains used because the phrase is recognisable in seconds and needs no context to read as mocking laughter after a trick.
