Pirulla is the online name of Paulo Miranda Nascimento, a Brazilian biologist and paleontologist who became one of Brazil's best known science communicators on YouTube. His long running channel focuses on evolution, vaccines, climate and debunking pseudoscience, which made phrases about detecting pseudoscience closely associated with his persona. As his clips circulated beyond YouTube into meme pages and messaging apps, this short excerpt was lifted as a standalone reaction. It remains popular in Portuguese speaking communities where it functions as shorthand for spotting unsupported health claims, horoscopes and viral misinformation.

Pirulla saying detector de pseudociência, the Brazilian biologist's catchphrase used as a reaction sound for dubious claims and fake science online today.
This is the voice of Brazilian biologist and science communicator Pirulla announcing his pseudoscience detector, spoken in Portuguese as detector de pseudociência. The short clip isolates the phrase with a dry, pointed delivery that sounds like an alarm going off for bad science. It lands instantly in a conversation, turning a dubious claim, miracle cure or conspiracy tip into a joke while also signalling real scepticism. The humour comes from the contrast between the serious scientific intent and the meme reaction format, making even a brief drop feel like a verdict on whatever was just shared.
