The short answer
Bater boca means to argue or exchange angry words. It is informal and usually suggests that the conversation became heated. It does not mean that anyone is literally hitting a mouth.
Use bater boca for a heated verbal argument
The common pattern is bater boca com alguém por causa de alguma coisa. Conjugate bater for the subject: bati, bateu, or bateram boca. Add a topic with por causa de when the reason matters.
Os vizinhos bateram boca por causa do barulho.
The neighbors argued because of the noise.
Não quero bater boca com você agora.
I don’t want to argue with you right now.
Eles discutiram o orçamento durante a reunião.
They discussed the budget during the meeting.
Compare bater boca with discutir
Discutir can mean to discuss a subject or argue with someone. Bater boca is more specific: it describes a verbal clash. In a work or academic context, discutir um tema can simply mean to consider or analyze the topic together.
Because bater boca sounds critical, use it carefully when describing another person’s disagreement. Disagreement can be calm and useful even when people do not reach the same conclusion.
A gente discutiu duas opções e escolheu a mais simples.
We discussed two options and chose the simpler one.
O casal começou a bater boca no estacionamento.
The couple started arguing in the parking lot.
