Para de flodar comes from Brazilian internet slang, where flodar is borrowed from the English flood and means sending a huge number of messages in a short time to overwhelm a chat. Clips like this circulate mainly as short WhatsApp audios and soundboard reactions in Portuguese-speaking communities. The Maria Cururu version became a handy shortcut for moderators and friends alike, because one short audio says what would otherwise take an annoyed text rant, and it stays funny even when used over and over in group conversations.
