Unfriggenbelievable
From Halopedia, the Halo wiki
Unfrigginbelievable [1] is a new killing spree medal in Halo: Reach that is awarded for killing 1000 enemies in a row on Campaign or Firefight without dying, and for killing 40 players in a row without dying in standard Multiplayer games. It is represented by an onyx/black hexagon with a cyan target in the center, in the same style as the old Halo 3 Invincible Medal.
