Geek bling is a term referring to computer parts worn as jewelry. It is generally ostentatious such as a net card hanging from a necklace but can be subtle as well, often used is a memory stick placed on a keychain. The term was coined by a student of Oak Hill Academy when the members of a Microsoft class took to wearing various computer parts from old computers on their key chains or lanyards. Any previous origins are unknown. It is alternately referred to as 'geek bling-bling' or on occasion '111001110' (binary for 'ice'). There is also classic geek-bling such as bowties and pocket protectors, as everyone knows pocket protectors are the pinnacle of geekdom.
