I don't think there are any rules to "AAVE" either, one speaker of this dialect? creole? language? or whatever we're calling it, would not be able to point out grammatical errors in the speech of another. I think the following would all be considered valid AAVE:
I ain’t tell nobody nothing about no sushi.
or
I didn’t tell nobody nothing about no sushi.
or
I didn’t tell nobody about no sushi.
or
I didn’t tell nobody about sushi.
All are bad English, i have no doubt whatsoever, that all would be understood by a speaker of "AAVE". I am of the opinion there is no such thing as AAVE, but there is definitely such a thing as people speaking bad English, which is reinforced by peer pressure and cultural and historical factors. Also I feel like people (educators in Oakland?) just caved, and don't want to admit that they have failed to properly educate and include a huge swathe of people.
