Wie sagt man BRO?

few decades ago people would only say mano in São Paulo state, but it has now spread throughout the country. If I’d have to guess before that, it was probably „Broder“. „Lek“ is also very popular in Rio de Janeiro (short form of moleque=kid)

Since Pata is synonymous with crispy pork in my country, the Philippines let me just make this sentence right here:

„You lookin kinda crispy bro“

Brazil uses lots of different words. not just one.
Mano, Meu, Parça, Irmão, Lek, etc.

It depends where in Brazil you are. In some places „cara“ is more commonly used. Also „bróder“ which is derivated from Brother. Or even irmão. But cara is used as much as mano.

The trisyllabic ones seem too long.
