Wanted to smack the kid!

The "slang" term MOPAR has been around since the 1930's. If you see anything automotive in nature you will hear the term. The term is still used at all Chrysler/Dodge dealerships. Chrysler sponsors a lot of functions as well. As for new slang terms, they spring up faster and go away faster that the latest Iphone. It would be difficult to keep current on anything with that short of a lifecycle.

Unfortunately the Cuda name was kind of short lived. Officially came out in 1969 and went away in 1974.
