Query: 'Cool' redefined

Connor's book somehow slipped by those who supposedly care about the subject. The pervasive term 'cool' means 'fashionable' or 'hip' to white folks but they're just the people who ought to read it. The definition changed for black folks long, long ago, but no one else seems to have written about it. No, it's not the first African-American word to be co-opted by a larger community, but the definitions are distinct.
