About the language.......right out of college I was working in one of those areas you don't want to be in at night. Or have a really good reason for being there in the day time. Felt really bad for those good people who had to endure it. And, there were quite a few.
At any rate I heard what I strongly expect are "those words" regularly used as nouns, adjectives, verbs, and adverbs. I can recall a surveillance when every third word from a group on the corner seemed to be "that word".
So, you might not like the language, but, for various classes of folks, it's just everyday terminology. Others use it for shock value-or to fit in with their group.
