This audio circulates online as a Brazilian Portuguese reaction meme centered on the phrase “obrigado, meu prefeito.” The available title and search patterns point to it being shared mainly for ironic posts about rain, flooding and city infrastructure rather than for a widely documented film or TV source. It spread through short meme edits, reposts and chat app forwards, where local humor and civic frustration make the line instantly readable. People still use it because the phrase is simple, quotable and easy to pair with real-life street footage.
