cultural shock

When I came to the States for the first time I did not experience any cultural shock, or at least I was not depressed, sad or anything like that. I was enjoying my time. But I did experience reverse cultural shock, when I got back.
This time I haven't experience any cultural shock upon arrival. But I've experience a great cultural shock yesterday and it did make me sad and very concerned about the US, society, my home country and many other things. The source of this cultural shock was Soulja Boy song. I loved the song a lot, but only yesterday I've decided to look up the lyrics and to find explanation to some expressions like "superman that hoe," "super soak," etc.
It is not just very sexual content. There are three very disturbing things about that. First, it is very dirty sexual expressions (and they refer to some very unfriendly/bad/disrespectful sexual practices).
Second, this song is written and performed by 15 or 16 year old boy. He is not supposed to know about that stuff... at least it is so inconsistent with my view of the world. Well, I guess, that is my personal issue.
Third, this song was aired all the time on major pop/top 40/hi-hpt stations. Basically people of all the ages heard that. I hope not all of them decided to look up the meaning of some expressions used in the song.

Well... and a little bit about song itself. If it is about what it seems to be about, then what is the value of the song? What is the value of the message?

I truly think things like that should be banned from radio stations. The bad this - I've heard the song today and, although I now know all the meaning of the phrases, this song still sounds catchy and makes me dance...
