The phrase combines Bolso, a shortened nickname widely associated with former Brazilian president Jair Bolsonaro, with covarde comunista, meaning cowardly communist in Portuguese. Both communist and coward are common insults in Brazil's heated online political slang, used by opposing camps to mock each other. Short clips like this spread through soundboards, WhatsApp groups and short video edits, where a familiar insult becomes reusable audio. Its popularity comes from that instant recognition, allowing creators to signal a political joke without explaining the context in the video itself.
