Based on the completely unnecessary and gratuitous
CG character
Jar Jar Binks in the Star Wars
prequel, _Phantom Menace_, it has come to refer to any overly obnoxious or heavy-laden computer-generated movie or character therein.
"This film
would've been ok except for the fact they
jar-jar'd it with all of those over-the-top effects."
"Did you see
Jet Li's _The One_? It was bad and a jar-jar extraordinaire!"
