bling-bling

bling-bling | 'bli NG , bli NG |
noun informal
expensive, ostentatious clothing and jewelry, or the wearing of them: behind the bling bling: are the diamonds worth it?

Origin 1990s: perhaps imitative of light reflecting off jewelry, or the jewelry clashing together.

Now that bling-bling is in the Oxford Dictionary, I don't know whether to be happy or upset. What's more, it not really a great definition. What's with all the perhaps stuff? Couldn't they call up the Cash Money Click and ask them what they meant?
