Can either be used as an expression for good or for bad, although usually to denominate something particularly good.

Used in place of good, great, awesome, bad etc.

The phrase was originated on the forum, "The Pit", by (now) esteemed user, Stratoblaster73, and has now spread to be a commonly used term not only on the tubes, but in real life as well.
