The state of being deliciously freaky. Used as an adjective by others to describe one whom is freakalicious. One cannot describe themself as freakalicious, unless told by others that they are. The reason for this is, well, one cannot sleep WITH themself, only BY themself.
A term generally used with people who only live for the thrill of the frag, with many games to become addicted to: Quake, Doom, Unreal Tourament, and many others.
It started with the first video games, Galaxia, and the need to kill everything on the sceen and secure your victory.
