doubleplusgood 

very, very good. from Orwell's "1984." as opposed to "plusgood," which means very good, and "good," which simply means, "good."

From a fictitious language called "Newspeak." Using Newspeak instead of English was supposed to prevent "thoughtcrime." (q.v.)

Oh, they renewed the Patriot Act? Doubleplusgood!

doubleplusungood 

adj: really, really bad.
Taken from the book 1984, where language is disintegrating, people build words using smaller words. The make-up of this word is as follows:
doubleplus - as opposed to just 'plus', which would mean 'really'
ungood - opposite of 'good', or 'bad'

That movie was doubleplusungood, it was horrible!

Jimmy thought the movie was doubleplusungood, since it starred Ben Affleck.
