Saw this today and not to nitpick, but......
.....black men typically don't say the word "cock." We'll say, "dick," "meat" or some other word, but you'll almost never hear a black man refer to a penis as a "cock." Just like you won't likely hear a black person say the C-word. In the film, Dale has a scene where he says "cock" four or five times. It just didn't ring true to me. This is one of the things that Linklater got wrong.
Sister, when I've raised hell, you'll know it!
