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!

It means very bad! Like, REALLY bad!

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

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!
