you a bitch
It’s called copula deletion, or zero copula. Many languages and dialects, including Ancient Greek and Russian, delete the copula (the verb to be) when the context is obvious.
So an utterance like “you a bitch” in AAVE is not an example of a misused you, but an example of a sentence that deletes the copular verb (are), which is a perfectly valid thing to do in that dialect, just as deleting an /r/ after a vowel is a perfectly valid thing to do in an upper-class British dialect.
What’s more, it’s been shown that copula deletion occurs in AAVE exactly in those contexts where copula contraction occurs in so-called “Standard American English.” That is, the basic sentence “You are great” can become “You’re great” in SAE and “You great” in AAVE, but “I know who you are” cannot become “I know who you’re” in SAE, and according to reports, neither can you get “I know who you” in AAVE.
In other words, AAVE is a set of grammatical rules just as complex and systematic as SAE, and the widespread belief that it is not is nothing more than yet another manifestation of deeply internalized racism.
The mind of the man who dreams is fully satisfied by what happens to him. The agonizing question of possibility is no longer pertinent. Kill, fly faster, love to your heart’s content. And if you should die, are you not certain of reawaking among the dead? Let yourself be carried along, events will not tolerate your interference. You are nameless. The ease of everything is priceless.
In ancient Pagan times in Ireland the poets were supposed to possess the gift of prophecy, and by certain means could throw themselves into a state in which they had lucid vision of coming events. This state, called Imbas for Osna, was produced by incantations and the offering of the flesh of a red pig, a dog, or a cat to their idols.
Then the poet, laying the two palms of his hands on his two cheeks, lay down and slept; his idol gods being beside him. And when he awoke he could see all things and foretell all things. He could make verses with the ends of his fingers, and repeat the same without studying, and in this way proved his right to be chief poet at the court of the king.
Also he laid his staff upon the head of a person, and thus he found out his name, and the name of his father and mother, and all unknown things that were proposed to him. And this prophetic power was also obtained by Imbas for Osna, though a different kind of offering was made to the idol.
