Being with someone who is respected in the neighborhood reduces the chance of a resident taking offense to the 'intrusion' and being unfriendly.

As goes for just about any social situation or party, a visitor should never carry any aggressive, over-confident, or negative attitude while attending a baile funk party, always be in good spirits and avoid giving bad looks to anyone in attendance.

notably, speaking loudly in a foreign language, especially while looking at people, can quickly be interpreted as offensive behavior and escalate into a confrontation - loud talking should be reserved for moments of direct conversations and not used while walking randomly in the crowds.

Rubbing someone the wrong way can quickly degenerate in a situation where the danger of ending up hurt  is considerable.
