Fujacktard

When someone is acting, both, like a 'Jackass" and a "Retard" and quite possibly over doing it as well.

"Did you hear what Sanders did last night?"
"Yep, what a total Fujacktard!"

fanjack 

Verb - when an online poll is flooded with votes by fans of a particular celebrity, TV show, movie, etc., making the results unreliable. A poll is usually fanjacked after a fan website draws attention to it. A portmanteau of the words fanatic and hijack.

Britney's album was voted Best of 2007? That poll was definitely fanjacked.
