This is an allegory to Hishamuddin Hussein who declared (his mouth is law) that yellow and Bersih are two illegal words. Which means, it is now added into the list of taboo words including Altantuya. But still the number one word that is considered dirty by anti-socialists is of course Socialism. Well, it is popular in Cuba and Venezuela, but I somehow remembered this rap that actor Warren Beatty performed in his satire movie Bulworth (this was 13 years ago).
Anyhow, I managed to dig up the video seen in You Tube, which the rap is a little of 3 minutes long. The rap is actually meant to make a long speech and Bulworth's truth confession a little more interesting with some amusing results of course.
