joking, but also meaning it

A term coined by Donald Trump on his show "The Apprentice" even though bosses used it all the time before. Now anyone who watched five minutes of it thinks it's THE ABSOLUTE SHIT and uses it to say "YOU SUCK!" or "LOSER!" or something of the sort.

I can see how you might think Al Franken had coined the expression if you had never heard it before, but it was an expression my mother when I was growing up -- and she died in 1984.

A Frankenism, meaning joking, but really meaning it.
