I said that to someone yesterday.
Then I googled it "don't make me no nevermind"
And the first thing to pop up was a website devoted to 'Hillbilly Speak'
It means: I don't care.
And somehow I knew that. When did I learn to speak like a hillbilly?
Does it bother me?
Don't make me no nevermind.
Point of the story:
I really don't care.
