"Bling-bling," the hip-hop term for showy diamond jewelry, has gone respectable: It will be in the next edition of the Oxford English Dictionary. The OED defines "bling-bling" as "expensive objects of jewelry that are worn in a way that is very easy to notice." Dictionary spokespeople said they included it because it has widespread use. According to MTV.com, "bling-bling" was coined by the rap group Cash Money Millionaires in the late 1990s. It gained national awareness with a song titled "Bling Bling" by Cash Money's BG. "I knew it was serious when I saw that the NBA championship ring for the Los Angeles Lakers had the word 'Bling Bling' written in diamonds on it," BG told the channel's Web site. "I just wish that I'd trademarked it, so I'd never have to work again."
