Portuguese-speaking meme pages call an obnoxious, hard-to-listen-to laugh a 'risada câncer', and this clip — credited to 'o amarelo' in its upload title — became a shorthand for that gag around Brazilian WhatsApp and TikTok circles. The identity behind the yellow nickname is not documented on the sound's page, so creators treat it as an anonymous reaction sound. It circulates in fail compilations and quote-reply memes where the laugh itself does the roasting, and its staying power comes from how instantly recognisable that ugly cackle is, even at under three seconds.
