I think your question is missing some words.
But don't ever give Brazilians the American "Ok" hand sign. It's like the finger over there.

Actually, it is offensive only when displayed with the back of the hand to the person, usually with all three fingers together, and usually not with a big smile on your face, like the image linked above.
No. The urban legend is that Brazilians find it offensive when you speak to them in Spanish, but this has no truth to it.
Brazilians find it offensive when people behave and speakto them in arrogant, condescending, discourteous, disrespectful, impatient and rude ways, because Brazilians tend to be an accommodating, easy going, hospitable and welcoming people that are tolerant of individual and cultural differences.
Brazilians find it offensive when you're disrespectful of other people's feelings and property. For they take pride in their country, their culture, their history, and their language. Their country is considered a melting pot of just about any culture and language in the world. With such a welcoming attitude towards other, Brazilians find it troubling when tourists and visitors don't return the hospitableness.
Not at all, that's our mother language. It's a little upseting, though, when people speak Spanish thinking that's our mother language. Most Brazilians will think it's pretty awesome you're speaking portuguese, quite funny, and will probably help you learn if you are up to.
Brazilians find it an offense when people speak to them in an arrogant, condescending, impatient or rude way. For Brazilians tend to be accommodating, easy going and hospitable. In fact, they're proud of their country's reputation as a melting pot of many cultures and languages. Consequently, they're used to trying to work out problems as amicably as possible. And so it's offensive to Brazilians when others don't respect the feelings and rights of others.
Brazilians find it offensive when guests, tourists, and visitors want to do everything in a hurry, speak impatiently and rudely, show a complete lack of manners, find fault with everything, and don't want to try Brazilian food.
No. Brazilians are used to some tourists, and indeed some people worldwide, not knowing that there even is such a thing as the Portuguese language. They also are used to other tourists, and indeed other people throughout the world, thinking that Brazilian Portuguese needs to be spoken according to the standards of Portugal or of the Spanish-speaking countries. And so Brazilians tend to be appreciative of Portuguese speakers, be they from Portugal or from any one of the former Portuguese colonies. For Brazilians tend to be easy-going, hospitable, and welcoming. Likewise, they tend not to find any one language offensive, because of Brazil being a melting pot of many cultures and languages. But what Brazilians tend not to appreciate is a rude, unappreciative attitude that disrespects the rights of others. And so it's neither the language nor the language speaker, but an attitude that may be offensive to Brazilians.
Brazilians don't find any language offensive in and of itself, but they get offended (as most people of non-Anglophone nations do) if you walk up to someone and assume they can speak English. if you ask them in Portuguese whether they speak English and thenspeak English it's another matter altogether.
No. Brazilians tend to be outgoing and openminded. For they realize that, as South America's largest country, they will survive only if they get along with each other, and with neighbors and visitors. And so they tend to like to share their acquaintance with their country's vast natural beauty, and exciting life, with guests.
I do believe it is Spanish. Brazillians Speak Portugese but it is a common mistake that many believe the speak Spanish.
No, you must consider that people worldwide, has different reactions of what is offensive. If I ask you the same question regarding to the US people, could you give me an answer ? Usually, what is offensive for a person can not affect other one. This question cannot be done on this way. It appears that all the brazilian people would get offended when somebody say a certain sentence or word. In other words, what is offensive to most of the brazilian people certainly would be offensive on the whole world. Take a look on a you tube video : "Everything is offensive. "
People born in Brazil, or people born to Brazilians abroad, are known as Brazilians.
