(exclamatory phrase) a playful way of giving kudos to someone who has achieved or done something special.

First used by Jon Stewart of The Daily Show when signifying the fact that Al Roker of The Today Show was the only person to enunciate the Icelandic volcano Eyjafjjoell more correctly than his peers. The phrase has also recently become somewhat interchangeable with OH SNAP, particularly in cases of giving recognition to funny insults.
