Ain't, too much informal ?

What's up folks, is everything fine ? I hope so.

I've been thinking about the way I'm going when I speak English, so, what I could notice was that:

- I'm quite often using "ain't". (informally talking)
- I'm saying "ni**a" too much. (informally talking)

What are you guys opinions about "ain't" and "ni**a" ?
Should I stop it ?

I have seen some English youtubers saying that, it's not good to say it.
I have this question because since i'm not a native speaker, I might sound so much desperate and forced.

Cheers!

Your Youtuber friends are right, if you are not living in some kind of hoods and is talking to some buddies. Yes, it´s waaaay informal.
Yeah, I've got some rap influences from there, that is why.
As I don't know the exact meaning of the most words, I got hooked on then for some points, such as pronnounce, or some stuff...

But I'll try to be more careful, since I'm going to do my master abroad, I wanna be polite, haha.

Cheers!

No problem, you can always use when singing along a rap tune, so you don´t miss it. :-) Good luck with your studies and congrats on the fact of English being the object of study.
