What did Materazzi really say?

What was it that got Zizou so upset?

He called him bald?

Much worse!

He called him a terrorist?

Much worse!

He called his sister a prostitute?

Much worse!

So what did he say?

Well, Materazzi asked Zizou "Bhaiyya hum chlormint kyun khaatey hain?"

So Zizou was compelled to butt him and say "Dobara mat poochna!"
