There really needs to be a Sarcasm Font for online use. I’d probably overuse it, intemperate as I am sometimes, but once in a great while I run across someone I’d like to run across with a railroad car.
My signoff did in fact chastise him for messing up “conniving.”
And once upon a time, I dropped in at the Auburn-Cord-Duesenberg Museum in Auburn, Indiana; the term is indeed applicable to the motorcar, and it’s only natural that it would eventually expand beyond its original use.
The origin of “doozy” turns out to be tricky. From urbandictionary.com:
perhaps alteration of daisy, and Duesenberg, a luxury car of the late 1920s and 1930s. It’s an English expression.
Here is what wikitionary.org has to say about the etymolgy of the word doozy also spelled duesy:
American, from daisy (the flower), also 18th century and onward English slang for something excellent. May have been influenced by Eleonora Duse, Italian actress.
If there’s anything to the witness descriptions of the gunfight “at the OK corral,” “daisy” was used in that sort of fashion in the early 1880s, so I can certainly believe the Deusenberg coinage probably did build on its similarity to “daisy.”
