Loquendo became widely known online as a text to speech system whose Portuguese voices narrated tutorials, parodies and early YouTube Poop style edits in Brazil and Portugal. Short clips cut from those videos later spread on soundboards and messaging apps, where single polite words in that recognisable synthetic voice turned into standalone jokes. Obrigado is one of the most reused examples because everyone understands the meaning even out of context. It survives as a quick, ironic thank you that needs no setup or explanation.
