Kurt Caz is an African man, so what is his native language?

Being South African, you're taught Afrikaans in school, and English. There's also Xhosa, and many other languages. But which language is Kurt Caz's mother tongue?

Most council estates in the UK speak a funny sort of English too!
Mostly swearing and a lot of asking "Who you looking at?" And then surprisingly they offer you something....'You want some?'

This guy is ashamed of his background. You can tell in the body language and choice of words to describe himself. "Funny English"? All English dialects are unique, and borrowed from their respective population groups. That goes for American, Australian, Indian, Nigerian and South African English. A psychoanalyst would conclude he travels so much because he is running away from himself...but I digress lol
