Bling-bling

bling-bling, n. term used to describe flashy or expensive jewelry; often shortened to just bling.
----
Addendum: Originally used in the late '90s by rap stars to describe their flashy jewelry, the term, as much urban speak does, has creeped across the culture to even be used by gamers.
Addendum 2: Could someone please kill this term? It belongs right up there with “ all your base”, but it just won't die!
