No. Not really, but close.
Back when I started using the internet I had to come up with a user name on AOHell. Everything I could think of related to my name was taken (unless I stuck some numbers on the end). So instead, I though of my favorite plane which is a Lockheed P-38 Lightning. Every iteration of that was taken too. I read a book once that talked about when the P-38 was in testing. Production test airplanes have always had a "Y" at the beginning of their identifier (YP back in the WWII days when fighters were called "Pursuit" planes, and YF since they got changed to "Fighter). So the Production test P-38s were YP-38s. They were gorgeous as they just polished aluminum and more streamlined than the final production aircraft. The workers at the Lockheed factory, according to the book, started calling them "Yippee 38s." It worked, and it stuck.
The plane in my avatar is the 5000th P-38 built. The "Yippee" on it comes from that original nickname. Unfortunately, that particular airplane crashed into some homes near the factory shortly after it was built.
