The total domination or shutdown of a person, place, or thing.
I pwned you Steven! 4 Killing Sprees, 2 Killing Frenzy's, 4 Triple Kills, 9 Assassinations, 82 Beat Downs, 23 Sniper Kills, 19 Sticks, 2 From the Grave Kills, and a Perfection!
An awesome sensation achieved by sniping someone through the eye and getting the Sniper Kill medal followed by winning the game.
Oh man, I just experienced Maloosticaria!
