The phrase tô creepando não, mané comes from Brazilian internet slang, where creepando borrows the English creeping to mean lurking or watching quietly, and mané is a Rio de Janeiro slang term for dude. The clip spread as a short soundboard and WhatsApp style audio, shared out of context as a ready made denial. Its popularity comes from how specific the wording feels while still fitting many situations, from gaming chats to social media comments, which keeps it circulating as a quick Brazilian meme reaction.
