Someone who holds on to once flashy or technologically advanced long after it has become passe or outmoded.
I can't believe Sharon still wears that Trucker Hat. That's one blingleberry that won't shake loose!
Like the term "dingleberry" which denotes a piece of shit or toilet paper that sticks to your ass hair. A "Blingleberry" is a piece of shit that is always hanging around (or on your ass), but has a great facade. Lots of labels, tech gadgets, great friends (bling) and not much else.
That blingleberry has on $600.00 jeans but stuck me with the check for dinner because he's "broke".
