Bling is a ghetto culture term for flashy jewelry worn by rappers. A lot of the drug dealers and pimps in my neighborhood wear a lot of bling to show off their wealth. Personally if I could afford such jewelry, I wouldn't live in the area of town I live in, but I grew up middle class, so my outlook is different.

As for what camera, I used to see doctors and lawyers wearing Leicas as jewlery all the time when I lived in Santa Fe, but that's rare here in Indiana even in wealthy communities. People here are too practical minded for that.
