What is Shareef?
1.
I just learned what that song was written about.
After the Ayatollah Khomeini started ruling Iran, one of the first things he did was to ban rock 'n' roll since he considered it a bad and corruptive influence.
The Clash wrote "Rock The Casbah" in response. So "Shareef" was the Ayatollah, even though that wasn't his real first name.
There's a computer-generated Shareef head in the cafe in Back To The Future II.

Some dude who don't like it.
