I wouldn't say that "ain't" isn't good English. It's not correct to use ain't in some social settings. It's slang. Be cautious with google. It's super helpful and I use it for Spanish but not everything you hear will be correctly translated. For more formal English you could use " I don't have any friends" Great question. Hope that helps. For more ways to speak more natural English, you can schedule a lesson with me.

Hi HongJu, The key here is that the two negative words -- 'ain't' and 'no' -- are used together to make the idea more intense. They are building on each other, not canceling each other out. "You ain't got no friends" is a more idiomatic or slangy way of saying, "You really don't have any friends." "You got no friends." would *also* work, because it's slangy in a similar way and keeps the meaning and some of the intensity. The grammar is idiomatic, but the meaning is clear. I disagree with Robert about there being "good English" and "bad English" in general. These are not formal sentences to use in a report. But you could see a fictional character in a novel, film, or TV show say this line.

Google is correct. The sentence with ain't is not good English, since ain't is not good English and there is a double negative. Your proposed correction, you got no friends, is not the best English either. Stick with Google. Other examples I ain't got time I ain't got no time ---- here no is used for emphasis of the negative, not for double negative I do not have time - good English I have no time -- good English
