Comes from the root - beast and beast mode. Also derived from the old Sega video game, "Altered Beast". This word describes a person that is well known to be awesome, and second, do awesome things. There is usually high adventure, high risk or high exertion involved... and also a high potential for beast noises while said activity is being performed.
