The phrase vai dormir seu marginal translates roughly to go to sleep, you marginal, in Portuguese and circulates online under the names Frank and Renegados. In Brazil it spread as a shareable voice clip for group chats, edits and soundboards, where short shouted lines work as instant reactions. Its popularity comes from how specific the insult sounds compared to a generic goodnight, making it easy to reuse whenever someone is awake far too late.
