Vamo is a colloquial Brazilian shortening of vamos, meaning let's go, while caralho is a strong Portuguese swear word that adds emphasis rather than a literal meaning. Together the phrase is a familiar, informal rallying cry in Brazil, heard in football stands, street celebrations and livestreams when excitement runs high. As a short audio clip it has circulated online as a reaction sound, shared by creators who want an instantly recognisable burst of Brazilian hype without needing a longer speech or song.
