I'm also bored, so let me tell you a tale about the origin of the word bling.
Rolls Royce make jet engines that run at rather high temperatures. These have turbines in them that have to withstand the high temperatures. One part of the turbine is manufactured from advanced fibre reinforced composites and other crazy materials. This part is known as a blade turbine ring, which was shortened by engineers to bling.
So all those rappers out there with their bling are using a term coined by the coolest of cats, engineers. How about that...
