20. Bling

For the first 8 years of the millennium, rappers made it a hobby to spend absurd amounts of money on diamond-encrusted platinum and gold chains. Bling—the onomatopoetic word for the sparkle of precious stones—is now an unforgettable part of pop culture. Bling is such a big part of 2000's hip-hop that we had Ben Baller break down the greatest chains of all time.
