Blingtard is a contraction of bling and retard. And is a response to the over abundance of bling on some persons, thinking that more is allways better.
This word originates from the virtual world Second Life, where one subculture is white boy gangster wannebe's Role Playing gangsters with to much Bling. But since the Bling in RL is getting to absurd levels, the word is starting to being used for RL bling retards as well.
This meaning of the word is used exclusively in the AFOL, or Adult Fans Of Lego community. It's a combination of the words clone (as in Star Wars Clone Troopers) and (re)tard.
The term refers to someone who buys a lot of the standard clone trooper figures, and then uses (or rather: abuses) his sharpies while trying (and most of the time failing) to draw cool legion colors on them. They most often adopt online names like "Commander Marks of the ### (fill in any 3 numbers) Legion" and build very shoddy and ugly builds. They react very defensively when somebody calls them a clonetard.
