Raggawhat?

While reading Chapter Nine of "White Teeth," there was mention of Millat's "gang" or "crew." They called themselves Raggastani's. I found this interesting because I had never heard this name at any point in my life and I like to think I'm quite well versed on notorious gangs. After doing some research, I found out that Raggastani is not a gang, rather, it is a deviation and play on words. If you noticed throughout these four chapters, Millat begins to act more and more like a Carribean native. He may even be imitating a Jamaican person. He talks in their slang and uses a lot of their mannerisms. Irie even comments on how he speaks, exclaiming "That is not your voice" and she keeps telling him how ridiculous he sounds. When I began to dig deeper, I found out that Ragga refers to a specific type of music. Basically, dance hall electric reggae. As absolutely ridiculous as I find that, it is real. The movement of music began in Jamaica and has slowly spread out. There are no famous Ragga songs or singers that I can mention, so I will just go on. From this, I gathered that Raggastani was basically just a conjunction of the word Ragga and the term Pakistani. Although Millat is from Bangladesh, I learned that they received their independence from Pakistan. Thus, I can see why Millat would refer to himself as a Raggastani. Basically, the characteristics of Raggastani's, from what I gathered, are darker skinned kids from either Indian, Pakistani, Bangaldeshi, etc. decent and that all of them acted like a Jamaican. Although it might seem odd, we have tons of groups like this in our society. We call white kids who act black "Wiggers," so it is not unusual for kids to adopt the idioms and mannerisms of another culture. The only question I have left is why Millat's group chose the Carribean culture as the one they wanted to emulate? It could be from all the pot, but other than that, there wasn't a great proliferation of Carribean natives in England, so why he chose them I have no rational explanation.
