This short Brazilian voice meme is known mainly through the line in which Gleison says he flunked physics while chemistry was a different story. It has travelled as a shareable reaction audio rather than as part of a larger show or song, passed between friends and reused in short videos about school life. Its staying power comes from how specific and relatable the joke is: almost everyone has one subject that defeats them and another that unexpectedly clicks, so the contrast still feels fresh whenever exam season returns.
