The phrase comes from everyday Brazilian Portuguese, where cê is a casual shortening of você and brava means angry or upset when speaking to a woman. As a short isolated recording it began circulating as a reusable reaction clip rather than as part of a longer scene, shared between friends and reused in edited videos. Its appeal is the timing and tone, which let people defuse tension or tease someone without typing an explanation. It remains popular because the question fits almost any small argument, rant or visibly irritated moment online today.
