“KEPT”
On a Mercedes being driven by a blue-hair.
I’ve seen ROFLMAO and WTF.
It’s French Connection United Kingdom, a clothing line and radio station. And yes, they did it deliberately. Coming soon to a tshirt near you.
Years ago I cooked at a local pancake house (not part of a chain). The owner’s truck bore a license plate that said PANCAKE. His wife’s car had SYRUP. His mom’s car had DOLLAR6 - “Dollar 6” was the abbreviation the waitresses wrote on the ticket to indicate “6 silver-dollar pancakes” which was what the Boss Mother ate for breakfast every day.
I misread a vanity plate in an amusing way some years ago, because I was reading it in my rearview mirror. It actually said “RIDE EM”, but what registered at first glance was “RIDE ME”. The plates were on a pickup truck with a damn fine-looking woman behind the wheel, so that probably had some influence on how I read the plate 
I saw the truck regularly around town, and judging by the bumper stickers, the woman owned horses and possibly participated in rodeos, so that would explain the “RIDE EM”.
SWEAVE (which I have come to learn means “fuck”). My English professor (a blue-haired, little old lady) had it on her Cadillac.
At the last place I worked, someone got away with:
NA2I
Which I found funny in the nonconformist kinda way, but I couldn’t imagine who would be ballsy enough to drive around with that one. I never checked for key marks on the side of the car, but I’d be surprised if they could get to the supermarket and back without sporting one.
I feel stupid. 
RGR MRTS on a hearse? RFID-TAG?
Help!
I saw one this morning that made me feel faintly ooky.
LAST SS
It’s probably some other SS than that well-known one, but still. Yerk.
I’ll offer a possible explanation: Some members of the Copyediting-L mailing list (also known as “CE-L”) refer to the group as “the CELery.” Could have been one of us.
Queen Tonya: RiGoR MoRTiS. (No idea on the other one.)
“RFID” (or Radio Frequency ID) tags are the kinds of tags that let you drive through the tollbooth without having to stop.
Someone at work has one that says “MOBLSUT”, I haven’t figured it out but I’m constantly misreading it as “MOB SLUT”.
And what’s with people that put their car models on their vanity tags? Like someone who drives a VW Passat and has a tag that says “PASSAT”. I don’t get it.
MOBiLe SUiT Gundam, maybe? A popular Japanese anime series.
That’s easy. They’re idiots.
In that vein, we’ve got the all-time dumb vanity plate winner in my area: THE CAR. :rolleyes:
Took me 30 seconds.
At my brother’s house they park their two grey and blue vehicles side by side.
The plates read DALLAS CWBOYS
My friends uncle had vanity plates that read: FLY9.
He was a younger guy so I thought he was just trying to be cool and hip. Kept meaning to ask what it meant for the longest time. Then I was invited to their annual Booyah and saw the rest of his families vanity plates and was finally able to put it all together.
FLY1, FLY2, FLY3, etc… up to FLY9.
Their family name was Fleischauker, hence the FLY1 etc…
On a full size SUV (Toyota Sequoia):
EARTHLVR
(So does LVR mean Lover or Leveler?)
I live near Johnson Space Center in Houston. One of our space walking astronauts had GO4EVA.
I knew someone who drove a Honda with the spooneristic plate “FENRY.” After coming out of the closet, a friend of mine got the plate “YESIAM” and plastered her rear bumper with rainbow, labrys and Melissa Etheridge stickers. I knew a couple whose plates reflected their educational goals “PHD2BE” and “JD2BE” respectively.
But the one that made me gag on my latte one morning was “SPLD RTN” on a Jaguar convertible driven by a girl who looked to be 18, tops. My suspicions about her age were further affirmed when she pulled into the student lot at the local high school. :rolleyes:
I once saw one that read HWY2HEL. Not offensive by most people’s standards, but I’m surprised my state’s DMV let this one pass.
The ones that usually draw my attention are single-letter vanity plates because of all the blank space they leave. I’ve seen a car around town with the letter C several times, and another one with a V, nothing else.
Side note: One time in a magazine that ran a “photo of the month” feature, it showed a car with the word “OOPS” on its license plate. Nothing too unusual about that, except that the car had been crashed into from the front.
I bet it was an 96 Impala SS; 1996 was the last year for the Impala SS, and some people were very sad about it. Big car, big engine. The non-SS impala is still made.
