Ah, yeah, I bet that’s it.
Scored a couple today:
-
QUNTM⎵LP on a standard plate on a Hyundai Tucson SUV / family wagon. Obviously “quantum leap”, but what’s the personal significance? Surely not their mighty Tucson?
-
JADMA on a 5-character wild horses conservation plate on a family wagon. Someone’s name?
Fan of a certain late '80s / early '90s science fiction TV series, perhaps. Bonus points if the driver said, “oh, boy” as you passed him.
It was parked near me when I exited a store today. Wasn’t there when I parked. Perhaps it time-traveled into the space while I was shopping. But if so the driver had time-traveled elsewhen and was nowhen to be found. 
BYETOGAS
I interpreted it at first as “Bye Togas,” and found it extremely mystifying. A Roman striptease artist, perhaps?
Then I figured it out.
On an EV presumably?
I have a number I’ve accumulated.
BAJUTO Spanish for short.
KEYCUTR Presumably a locksmith but the Metris sporting it had no commercial markings.
DARKSBR Darksaber? No marks on this one, either.
1MOKAY Glad to hear it.
BLINGAZ Not a trace of bling anywhere that I could see.
GET MVN Impatient, aren’t we?
Saw a small Range Rover SUV today with MMSY16 all run together like that. I’m suspecting some well-off young woman (nick-)named Missy got a very nice 16th birthday present to go w her shiny new driver’s license.
The car was parked so I didn’t get a chance to see the driver.
Probably. By the time I thought to look, maybe 20 seconds after I’d made my first (incorrect) interpretation, I’d turned off the road and it was gone.
While on my way to a doctor appointment this morning I saw a Hummer with an MD plate: CARING. He seemed to be caring about getting to where he was going quickly rather than safely, weaving through traffic with no blinkers.
Maybe he’s more into Car-ing, as in driving like a racer. Or perhaps he works in the Emergency Department and was trying to drum up some extra business on the way in. 
I’ve never lived in a state with special plates for medical people. I wonder how common that is? Seems like something you see on TV, not IRL. I’m not doubting you saw one wherever you are; I just think I’ve never done so.
At the ski area this weekend TYP2FN = type 2 fun and NTNYLN = Nittnay Lions
I don’t know where @Topologist is. I live in NY state. Some physicians have them here (not all, but they’re pretty common).
I read “MD” as Maryland. No?
There’s a recurring character in a series of novels (Andy Kelp, a career petty thief, in Donald E. Westlake’s Dortmunder series) who steals cars from long-term parking lots at JFK airport. He prefers cars with MD plates, supposedly because they are immune to getting parking tickets in NYC. I don’t know if it’s true or not, but that’s the first time I ever heard of MD plates. In fact, it’s the only place I’d ever seen reference to them.
New York state has “MD” plates for doctors:
I don’t know if any other states do. I believe @Topologist was referring to doctor plates, not Maryland plates.
In fact they have 32 flavors of professional plates for various professions:
The problem I always have, and the reason I don’t post in this thread that often, is that I will see a custom plate, but I can’t write it down or photograph it because I’m driving, and then by the time I am able to post here I’ve forgotten exactly what the plate said.
Like this morning on my way to work I saw somethingRUTH. I remember the “RUTH” part because it’s a name and easy to remember. But there were three letters before that, and I’ll be damned if I can remember them now.
Good haul today.
RAZZZEL
BIG JUCY
LVDASEA This one I’m not sure about.
PSA 1YR This might be a false positive. It fits one of the many standard plate sequences in Arizona.
Just saw KRKSKNR
If it is indeed Kirk Skinner, he’s doing a fine job of identifying himself and his pickup.
Otherwise, I got nothin’.
