Vale tudo means anything goes in Portuguese and names a Brazilian full contact fighting tradition that emerged in the early twentieth century with very few rules. The format helped shape modern mixed martial arts and became widely known outside Brazil through early MMA events in the 1990s. Online, the phrase has outgrown the ring and is now used as shorthand for any situation with no limits, which is why this short shout circulates on soundboards as a reaction for wild, unrestricted moments.
