Marvy
"Marvy" is a slang word coined in the mid-Sixties. It's short for "marvelous." The word has since fallen out of popular use.
I say we bring it back. I will endeavor to season my discourse with it, being careful of course not to overuse it. If you all do the same, I bet we can have the word back in common usage by the end of the year.
Or maybe not. But I'm going to have fun with it anyway, because… Well, just because.
