The best one I've seen was on a little red sports car that was fueling up for gas. I looked at the plate and was clueless, so just asked the rather smug looking guy what it meant. He said it meant BORED. Only it was in French..something like enqui(?). Now, if anyone knows FRENCH, please reply and give the exact spelling. The second best is HITEST..as the driver is a fiesty lady that drives like she and car are both on really HIGH TEST gas. Both were seen in TENNESSEE, but I don't know what state the Sports car represented.
