doubleplus 

1. A prefix used to create the superlative form of an adjective or adverb. Also used for emphasis to stress an idea/emotion. Is superior to the prefix "plus."
ex.
doubleplusgood = fantastic/wonderful/amazing/etc.
plusgood = great/fine/better/etc.

This term originated from George Orwell's novel, 1984 as a part of the modified English language of Newspeak. In the book, doubleplus was used to eliminate "unnecessary" words to limit one's vocabulary/ability to express.

from the book...
"If you want a stronger version of "good", what sense is there in having a whole string of vague useless words like "excellent" and "splendid" and all the rest of them? "Plusgood" covers the meaning, or "doubleplusgood" if you want something stronger still. "

doubleplus unleet

A fusion of newspeak and leetspeak to indicate that something is superlatively bad. Alternatively, "!1337++," "++!1337"
NOT RECOMMENDED for use in verbal conversation, as it makes the speaker sound like a complete t00l.

A tool, in daily conversation: "Arrgh! That memo about the new dress code is doubleplus unleet! No more pocket protectors!"
A l33t haxx0r, in e-mail/im: "WinME+56k+hateway=!1337++, -kthxbai (And yes, I actually ran on that through 2003)"
