Translation - English-Spanish - You're a friend of my black bro, am I right? hiihi hello

I had to improve the initial text because it was slang, with many possible translations.
This translation is the most accurate and the easiest to be understood.
I guess i can leave "bro", instead of brother, as it has been intentionally written like this in the submitted text.

It's no slang, just plain Spanish.
No es jerga, sólo español llano.
