I got that from young black girls and a few black boys in middle and high school. Sometimes white boys and girls listened out of curiosity because I happen to be in the south and a "proper" speaking black boy was an oddity back then. To black kids, they thought I was trying to be better than them, which wasn't true. They only saw these people on tv and the movies. For me, speaking proper was my one and only act of defiance against the south.
My male cousins on my mother's side call each other Ike from time to time. I often wondered why they called each other that name.
