The name risada is Portuguese for laughter, and this short version circulates online as a compact meme laugh with no widely documented original recording or creator. It spread through short video edits, gaming clips and messaging apps where a four second reaction is easier to share than a long laugh track. Portuguese speaking creators in particular reuse it as a quick audio shorthand for finding something silly, and its clipped length helped it survive as an editing staple rather than a one off joke.
