Fat Dreams:
I'll start with one I just learned recently: "executive." I love how it connotes both power and opulence.
Munchies:
Never heard of using executive as a euphemism for fat. How does that work?
Fat Dreams:
Apparently in men's fashion "executive-cut" and "executive fit" is sometimes a synonym for plus size. Maybe it has the same roots as the term "fat cat" but that's just a guess.
Doing a checking educate, my friend.
