When talking about if grammar is important or not, It is beneficial if we understand what in what context we find ourselves in. If it is between you and your friends, Then grammar is not too important. However, When making an argument against someone or speaking to someone of importance, Grammar becomes a vital tool.
This is in order to make your argument not only sound more sophisticated by also more convincing to the person you are talking to.
Grammar ain't nothin' 'cause you ain't got to say nothin' perfect, All that fluff and shit ain't necessary to get your point up there.
We got this thing called a dialect, And we got them colloquialisms. All that there shit automatically coincides with this thing we got in our heads known as a "frame of reference. " Some ninny ass in Newark, New Jersey, Is gonna read this and he ain't gonna know shit. Hillbilly outta West Virginia or frog lip outta Louisiana read this they gonna know word for word, Heart to heart fam.
Now, With all of that considered, Grammar essentially don't mean shit, And Grammar don't mean shit if you can yell loud enough, Neither.
